8 is American Bass's 8 inch at 37.2 Hz, a Qts of 0.35, 5.0 litres of Vas and 600 W RMS. This cabinet gives it 1.36 cubic feet net behind a 2.25 inch three-layer baffle, vented at 33.0 Hz through a 21.9 square inch slot beside the woofer, for an anechoic F3 of 28.0 Hz in a 30 by 14 by 12.9 inch front-firing box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThreaded insert kit ships with this box.\u003c\/strong\u003e American Bass does not publish the mounting hole locations for the VFL Comp 8, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape. You set the inserts when you mount the woofer, and this box ships with one kit.\u003c\/p\u003e\n  \u003cp\u003eSealed, the VFL Comp 8 needs 0.06 cubic feet net to reach a Qtc of 0.707. Vented, it trades that for deeper extension. The slot is gated at 720 W, 1.2 times American Bass's rating: the channel runs 21.4 m\/s and the mouth 12.6, and the cone peaks at 10.1 of its 13 mm with the subsonic filter in place.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eWhat makes it Professional\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThree-layer baffle, flush mount\u003c\/h4\u003e\n\u003cp\u003eThree layers of 3\/4 inch Langboard Elite make a 2.25 inch\n    front.

The channel runs 7.38 inches along its wall and turns once along the back wall for another 18.87 inches, which is why a 33.0 Hz tuning fits a 12.88 inch deep box.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eWhy this is a Professional build\u003c\/h4\u003e\n\u003cp\u003eEvery driver is run through the Performance Optimized wedge and down-fire before this chassis; the Professional box is where a driver lands when that smaller envelope, 30 inches wide and 18 inches deep with a triangular side port, cannot give it what it needs at its rated power. The VFL Comp 8 did not clear the port gate there. The calmest wedge port that fits that envelope is 13.0 square inches at 29.0 by 9.62 by 13.90 inches, and its mouth runs 17.3 metres per second at 600 W against the 17 metres per second line where a port starts to chuff. That port would stay clean to about 576 W. The slot on this box reaches 21.9 square inches and holds the mouth at 12.6 metres per second at 720 W.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eWhat the price covers\u003c\/h4\u003e\n\u003cp\u003eEvery Professional cabinet is priced the same way, by its size: this one is 3.13 cubic feet outside.

Two windowed braces run front to back either side of the woofer, clearing the cutout by two and a half inches. The box ships dry: polyfill detunes a ported alignment. Inside the 30 by 14 Professional envelope for a single 8, 12.9 inches deep. 8.71 inch frame, flush in the outer baffle layer, 7.40 inch cutout, 5.43 inches of mounting depth. It ships as a parcel.\u003c\/p\u003e\n  \u003cp\u003eAmerican Bass publishes Fs, Qts, Vas, cone area and Xmax for the VFL Comp 8 on its product page, but no overall frame diameter, no driver displacement and no Cms. The frame is taken as 8.71 inches, the larger of the nominal size plus half an inch and the 7.40 inch cutout plus a typical flange, so the baffle is never cut short; the 0.055 cubic feet of displacement is our estimate from comparable 8 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 13 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. American Bass does not publish the mounting hole locations for the VFL Comp 8, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape.

The frame is taken as 10.69 inches, the larger of the nominal size plus half an inch and the 9.24 inch cutout plus a typical flange, so the baffle is never cut short; the 0.068 cubic feet of displacement is our estimate from comparable 10 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 12 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. American Bass does not publish the mounting hole locations for the DX 10, so we cannot install the threaded inserts before it ships.

10 D4 is American Bass's 10 inch at 41.5 Hz, a Qts of 0.60, 17.0 litres of Vas and 700 W RMS. This cabinet gives it 0.83 cubic feet net behind a 2.25 inch three-layer baffle, vented at 40.0 Hz through a 18.8 square inch slot beside the woofer, for an anechoic F3 of 37.0 Hz in a 30 by 14 by 9.8 inch front-firing box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThreaded insert kit ships with this box.\u003c\/strong\u003e American Bass does not publish the mounting hole locations for the Hawk Slim 10 D4, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape. You set the inserts when you mount the woofer, and this box ships with one kit.\u003c\/p\u003e\n  \u003cp\u003eSealed, the Hawk Slim 10 D4 needs 1.51 cubic feet net to reach a Qtc of 0.707. Vented, it trades that for deeper extension. The slot is gated at 840 W, 1.2 times American Bass's rating: the channel runs 21.7 m\/s and the mouth 12.1, and the cone peaks at 9.3 of its 10.5 mm with the subsonic filter in place.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eWhat makes it Professional\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThree-layer baffle, flush mount\u003c\/h4\u003e\n\u003cp\u003eThree layers of 3\/4 inch Langboard Elite make a 2.25 inch\n    front.

The channel runs 4.50 inches along its wall and turns once along the back wall for another 21.22 inches, which is why a 40.0 Hz tuning fits a 9.75 inch deep box.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eWhy this is a Professional build\u003c\/h4\u003e\n\u003cp\u003eEvery driver is run through the Performance Optimized wedge and down-fire before this chassis; the Professional box is where a driver lands when that smaller envelope, 30 inches wide and 18 inches deep with a triangular side port, cannot give it what it needs at its rated power. The Hawk Slim 10 D4 did not clear the channel 23.0 m\/s over 0.55 x core 41.2 gate there: the nearest wedge that fits is 29.5 by 7.88 by 12.79 inches with a 18.4 square inch port, and no tuning, width or depth inside that envelope passes.

Inside the 30 by 14 Professional envelope for a single 10, 9.8 inches deep. 10.86 inch frame, flush in the outer baffle layer, 9.41 inch cutout, 3.15 inches of mounting depth. It ships as a parcel.\u003c\/p\u003e\n  \u003cp\u003eAmerican Bass publishes Fs, Qts, Vas, cone area and Xmax for the Hawk Slim 10 D4 on its product page, but no overall frame diameter, no driver displacement and no Cms. The frame is taken as 10.86 inches, the larger of the nominal size plus half an inch and the 9.41 inch cutout plus a typical flange, so the baffle is never cut short; the 0.040 cubic feet of displacement is our estimate from comparable 10 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 10.5 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. American Bass does not publish the mounting hole locations for the Hawk Slim 10 D4, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape.

The frame is taken as 10.51 inches, the larger of the nominal size plus half an inch and the 9.06 inch cutout plus a typical flange, so the baffle is never cut short; the 0.043 cubic feet of displacement is our estimate from comparable 10 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 9 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. American Bass does not publish the mounting hole locations for the SL 10, so we cannot install the threaded inserts before it ships.

American Bass's 10 inch at 39.0 Hz, a Qts of 0.45, 11.6 litres of Vas and 800 W RMS. This cabinet gives it 1.62 cubic feet net behind a 2.25 inch three-layer baffle, vented at 34.0 Hz through a 28.1 square inch slot beside the woofer, for an anechoic F3 of 28.7 Hz in a 30 by 14 by 14.9 inch front-firing box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThreaded insert kit ships with this box.\u003c\/strong\u003e American Bass does not publish the mounting hole locations for the VFL 10, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape. You set the inserts when you mount the woofer, and this box ships with one kit.\u003c\/p\u003e\n  \u003cp\u003eSealed, the VFL 10 needs 0.28 cubic feet net to reach a Qtc of 0.707. Vented, it trades that for deeper extension. The slot is gated at 960 W, 1.2 times American Bass's rating: the channel runs 23.6 m\/s and the mouth 15.1, and the cone peaks at 11.0 of its 14 mm with the subsonic filter in place.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eWhat makes it Professional\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThree-layer baffle, flush mount\u003c\/h4\u003e\n\u003cp\u003eThree layers of 3\/4 inch Langboard Elite make a 2.25 inch\n    front.

The channel runs 8.88 inches along its wall and turns once along the back wall for another 16.90 inches, which is why a 34.0 Hz tuning fits a 14.88 inch deep box.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eWhy this is a Professional build\u003c\/h4\u003e\n\u003cp\u003eEvery driver is run through the Performance Optimized wedge and down-fire before this chassis; the Professional box is where a driver lands when that smaller envelope, 30 inches wide and 18 inches deep with a triangular side port, cannot give it what it needs at its rated power. The VFL 10 did not clear the port gate there. The calmest wedge port that fits that envelope is 18.4 square inches at 25.5 by 10.12 by 15.04 inches, and its mouth runs 18.7 metres per second at 800 W against the 17 metres per second line where a port starts to chuff. That port would stay clean to about 657 W.

The frame is taken as 10.58 inches, the larger of the nominal size plus half an inch and the 9.13 inch cutout plus a typical flange, so the baffle is never cut short; the 0.078 cubic feet of displacement is our estimate from comparable 10 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 14 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. American Bass does not publish the mounting hole locations for the VFL 10, so we cannot install the threaded inserts before it ships.

The frame is taken as 10.69 inches, the larger of the nominal size plus half an inch and the 9.24 inch cutout plus a typical flange, so the baffle is never cut short; the 0.076 cubic feet of displacement is our estimate from comparable 10 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 13 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. American Bass does not publish the mounting hole locations for the XD 10, so we cannot install the threaded inserts before it ships.

is American Bass's 10 inch at 40.9 Hz, a Qts of 0.56, 8.1 litres of Vas and 1000 W RMS. This cabinet gives it 1.77 cubic feet net behind a 2.25 inch three-layer baffle, vented at 34.0 Hz through a 31.2 square inch slot beside the woofer, for an anechoic F3 of 28.2 Hz in a 30 by 14 by 16.0 inch front-firing box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThreaded insert kit ships with this box.\u003c\/strong\u003e American Bass does not publish the mounting hole locations for the XR 10 D4, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape.

Vented, it trades that for deeper extension. The slot is gated at 1200 W, 1.2 times American Bass's rating: the channel runs 24.8 m\/s and the mouth 16.4, and the cone peaks at 12.1 of its 13.65 mm with the subsonic filter in place.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eWhat makes it Professional\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThree-layer baffle, flush mount\u003c\/h4\u003e\n\u003cp\u003eThree layers of 3\/4 inch Langboard Elite make a 2.25 inch\n    front.

The channel runs 9.75 inches along its wall and turns once along the back wall for another 16.11 inches, which is why a 34.0 Hz tuning fits a 16.00 inch deep box.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eWhy this is a Professional build\u003c\/h4\u003e\n\u003cp\u003eEvery driver is run through the Performance Optimized wedge and down-fire before this chassis; the Professional box is where a driver lands when that smaller envelope, 30 inches wide and 18 inches deep with a triangular side port, cannot give it what it needs at its rated power. The XR 10 D4 did not clear the port gate there. The calmest wedge port that fits that envelope is 18.4 square inches at 24.5 by 10.75 by 15.66 inches, and its mouth runs 21.5 metres per second at 1000 W against the 17 metres per second line where a port starts to chuff. That port would stay clean to about 623 W.

Inside the 30 by 14 Professional envelope for a single 10, 16.0 inches deep. 10.66 inch frame, flush in the outer baffle layer, 9.21 inch cutout, 7.08 inches of mounting depth. It ships as a parcel.\u003c\/p\u003e\n  \u003cp\u003eAmerican Bass publishes Fs, Qts, Vas, cone area and Xmax for the XR 10 D4 on its product page, but no overall frame diameter, no driver displacement and no Cms. The frame is taken as 10.66 inches, the larger of the nominal size plus half an inch and the 9.21 inch cutout plus a typical flange, so the baffle is never cut short; the 0.087 cubic feet of displacement is our estimate from comparable 10 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 13.65 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. The slot mouth runs 16.4 m\/s at the gate power against a 17 m\/s limit, so this is a box to run at its rating, not past it. American Bass does not publish the mounting hole locations for the XR 10 D4, so we cannot install the threaded inserts before it ships.

The frame is taken as 12.59 inches, the larger of the nominal size plus half an inch and the 11.10 inch cutout plus a typical flange, so the baffle is never cut short; the 0.091 cubic feet of displacement is our estimate from comparable 12 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 11 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. American Bass does not publish the mounting hole locations for the DX 12, so we cannot install the threaded inserts before it ships.

Velocity 12 is American Bass's 12 inch at 32.1 Hz, a Qts of 0.30, 21.2 litres of Vas and 2200 W RMS. This cabinet gives it 3.61 cubic feet net behind a 2.25 inch three-layer baffle, vented at 32.5 Hz through a 68.9 square inch slot beside the woofer, for an anechoic F3 of 27.6 Hz in a 32 by 16 by 24.8 inch front-firing box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThreaded insert kit ships with this box.\u003c\/strong\u003e American Bass does not publish the mounting hole locations for the HD Velocity 12, so we cannot install the threaded inserts before it ships.

Vented, it trades that for deeper extension. The slot is gated at 2640 W, 1.2 times American Bass's rating: the channel runs 21.7 m\/s and the mouth 16.8, and the cone peaks at 14.0 of its 17.5 mm with the subsonic filter in place.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eWhat makes it Professional\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThree-layer baffle, flush mount\u003c\/h4\u003e\n\u003cp\u003eThree layers of 3\/4 inch Langboard Elite make a 2.25 inch\n    front.

The channel runs 16.25 inches along its wall and turns once along the back wall for another 11.38 inches, which is why a 32.5 Hz tuning fits a 24.75 inch deep box.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eWhy this is a Professional build\u003c\/h4\u003e\n\u003cp\u003eEvery driver is run through the Performance Optimized wedge and down-fire before this chassis; the Professional box is where a driver lands when that smaller envelope, 30 inches wide and 18 inches deep with a triangular side port, cannot give it what it needs at its rated power. The HD Velocity 12 did not clear the port gate there. The calmest wedge port that fits that envelope is 24.7 square inches at 29.0 by 12.25 by 17.89 inches, and its mouth runs 29.4 metres per second at 2200 W against the 17 metres per second line where a port starts to chuff. That port would stay clean to about 734 W.

Two windowed braces run front to back either side of the woofer, clearing the cutout by two and a half inches. The box ships dry: polyfill detunes a ported alignment. Inside the 32 by 16 Professional envelope for a single 12, 24.8 inches deep. 12.83 inch frame, flush in the outer baffle layer, 11.34 inch cutout, 9.02 inches of mounting depth. It ships as a parcel.\u003c\/p\u003e\n  \u003cp\u003eAmerican Bass publishes Fs, Qts, Vas, cone area and Xmax for the HD Velocity 12 on its product page, but no overall frame diameter, no driver displacement and no Cms. The frame is taken as 12.83 inches, the larger of the nominal size plus half an inch and the 11.34 inch cutout plus a typical flange, so the baffle is never cut short; the 0.153 cubic feet of displacement is our estimate from comparable 12 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 17.5 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. The slot mouth runs 16.8 m\/s at the gate power against a 17 m\/s limit, so this is a box to run at its rating, not past it. American Bass does not publish the mounting hole locations for the HD Velocity 12, so we cannot install the threaded inserts before it ships.

Inside the 32 by 16 Professional envelope for a single 12, 17.4 inches deep. 12.83 inch frame, flush in the outer baffle layer, 11.34 inch cutout, 7.68 inches of mounting depth. It ships as a parcel.\u003c\/p\u003e\n  \u003cp\u003eAmerican Bass publishes Fs, Qts, Vas, cone area and Xmax for the Hawk 12 on its product page, but no overall frame diameter, no driver displacement and no Cms. The frame is taken as 12.83 inches, the larger of the nominal size plus half an inch and the 11.34 inch cutout plus a typical flange, so the baffle is never cut short; the 0.130 cubic feet of displacement is our estimate from comparable 12 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 15.5 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. The slot mouth runs 16.6 m\/s at the gate power against a 17 m\/s limit, so this is a box to run at its rating, not past it. American Bass does not publish the mounting hole locations for the Hawk 12, so we cannot install the threaded inserts before it ships.

12 is American Bass's 12 inch at 30.7 Hz, a Qts of 0.44, 67.2 litres of Vas and 600 W RMS. This cabinet gives it 1.44 cubic feet net behind a 2.25 inch three-layer baffle, vented at 33.0 Hz through a 21.8 square inch slot beside the woofer, for an anechoic F3 of 38.1 Hz in a 32 by 16 by 11.2 inch front-firing box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThreaded insert kit ships with this box.\u003c\/strong\u003e American Bass does not publish the mounting hole locations for the Titanium 12, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape. You set the inserts when you mount the woofer, and this box ships with one kit.\u003c\/p\u003e\n  \u003cp\u003eSealed, the Titanium 12 needs 1.51 cubic feet net to reach a Qtc of 0.707. Vented, it trades that for deeper extension. The slot is gated at 720 W, 1.2 times American Bass's rating: the channel runs 19.1 m\/s and the mouth 10.7, and the cone peaks at 8.4 of its 12 mm with the subsonic filter in place.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eWhat makes it Professional\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThree-layer baffle, flush mount\u003c\/h4\u003e\n\u003cp\u003eThree layers of 3\/4 inch Langboard Elite make a 2.25 inch\n    front.

The channel runs 6.00 inches along its wall and turns once along the back wall for another 18.13 inches, which is why a 33.0 Hz tuning fits a 11.25 inch deep box.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eWhy this is a Professional build\u003c\/h4\u003e\n\u003cp\u003eThe Titanium 12 also builds in the Performance Optimized ported wedge and ported down-fire, the smaller and cheaper boxes. The Professional cabinet is the step up for it: a 2.25 inch three-layer baffle with the woofer flush in the outer layer, and a slot port gated at 720 W.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eWhat the price covers\u003c\/h4\u003e\n\u003cp\u003eEvery Professional cabinet is priced the same way, by its size: this one is 3.33 cubic feet outside. Delivery to the 48 states is inside the price; it ships as a 53 lb parcel and checkout adds nothing. The Performance Optimized 12 inch ported wedge is $399.99. The $32 difference is the larger box and the port this driver needs to run at its rating.\u003c\/p\u003e\n\u003c\/div\u003e\n    \n  \u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eThe cabinet\u003c\/h3\u003e\n  \u003cp\u003e32.00\" W x 16.00\" H x 11.25\" D external. Two windowed braces run front to back either side of the woofer, clearing the cutout by two and a half inches. The box ships dry: polyfill detunes a ported alignment. Inside the 32 by 16 Professional envelope for a single 12, 11.2 inches deep. 12.50 inch frame, flush in the outer baffle layer, 11.01 inch cutout, 4.45 inches of mounting depth. It ships as a parcel.\u003c\/p\u003e\n  \u003cp\u003eAmerican Bass publishes Fs, Qts, Vas, cone area and Xmax for the Titanium 12 on its product page, but no overall frame diameter, no driver displacement and no Cms. The frame is taken as 12.50 inches, the larger of the nominal size plus half an inch and the 11.01 inch cutout plus a typical flange, so the baffle is never cut short; the 0.071 cubic feet of displacement is our estimate from comparable 12 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 12 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. American Bass does not publish the mounting hole locations for the Titanium 12, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape.

The frame is taken as 13.01 inches, the larger of the nominal size plus half an inch and the 11.52 inch cutout plus a typical flange, so the baffle is never cut short; the 0.119 cubic feet of displacement is our estimate from comparable 12 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 13 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement.

American Bass's 15 inch at 30.4 Hz, a Qts of 0.56, 89.6 litres of Vas and 500 W RMS. This cabinet gives it 2.37 cubic feet net behind a 2.25 inch three-layer baffle, vented at 31.5 Hz through a 24.8 square inch slot beside the woofer, for an anechoic F3 of 34.4 Hz in a 36 by 18 by 12.2 inch front-firing box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThreaded insert kit ships with this box.\u003c\/strong\u003e American Bass does not publish the mounting hole locations for the DX 15, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape. You set the inserts when you mount the woofer, and this box ships with one kit.\u003c\/p\u003e\n  \u003cp\u003eSealed, the DX 15 needs 5.33 cubic feet net to reach a Qtc of 0.707. Vented, it trades that for deeper extension. The slot is gated at 600 W, 1.2 times American Bass's rating: the channel runs 18.4 m\/s and the mouth 10.4, and the cone peaks at 6.7 of its 12.5 mm with the subsonic filter in place.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eWhat makes it Professional\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThree-layer baffle, flush mount\u003c\/h4\u003e\n\u003cp\u003eThree layers of 3\/4 inch Langboard Elite make a 2.25 inch\n    front.

The channel runs 7.00 inches along its wall and turns once along the back wall for another 8.64 inches, which is why a 31.5 Hz tuning fits a 12.25 inch deep box.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eWhy this is a Professional build\u003c\/h4\u003e\n\u003cp\u003eThe DX 15 also builds in the Performance Optimized ported wedge, the smaller and cheaper box.

Inside the 36 by 18 Professional envelope for a single 15, 12.2 inches deep. 15.50 inch frame, flush in the outer baffle layer, 13.90 inch cutout, 7.10 inches of mounting depth. It ships as a parcel.\u003c\/p\u003e\n  \u003cp\u003eAmerican Bass publishes Fs, Qts, Vas, cone area and Xmax for the DX 15 on its product page, but no overall frame diameter, no driver displacement and no Cms. The frame is taken as 15.50 inches, the larger of the nominal size plus half an inch and the 13.90 inch cutout plus a typical flange, so the baffle is never cut short; the 0.167 cubic feet of displacement is our estimate from comparable 15 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 12.5 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. American Bass does not publish the mounting hole locations for the DX 15, so we cannot install the threaded inserts before it ships.

The frame is taken as 15.50 inches, the larger of the nominal size plus half an inch and the 13.50 inch cutout plus a typical flange, so the baffle is never cut short; the 0.172 cubic feet of displacement is our estimate from comparable 15 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 14 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement.

15 is American Bass's 15 inch at 28.5 Hz, a Qts of 0.31, 52.7 litres of Vas and 3000 W RMS. This cabinet gives it 4.37 cubic feet net behind a 2.25 inch three-layer baffle, vented at 37.0 Hz through a 107.2 square inch slot beside the woofer, for an anechoic F3 of 31.0 Hz in a 35 by 18 by 25.2 inch front-firing box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThreaded insert kit ships with this box.\u003c\/strong\u003e American Bass does not publish the mounting hole locations for the Hurricane 15, so we cannot install the threaded inserts before it ships.

You set the inserts when you mount the woofer, and this box ships with one kit.\u003c\/p\u003e\n  \u003cp\u003eSealed, the Hurricane 15 needs 0.43 cubic feet net to reach a Qtc of 0.707. Vented, it trades that for deeper extension. The slot is gated at 3600 W, 1.2 times American Bass's rating: the channel runs 20.8 m\/s and the mouth 17.0, and the cone peaks at 12.6 of its 25 mm with the subsonic filter in place.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eWhat makes it Professional\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThree-layer baffle, flush mount\u003c\/h4\u003e\n\u003cp\u003eThree layers of 3\/4 inch Langboard Elite make a 2.25 inch\n    front.

The channel runs 15.00 inches along its wall and turns once along the back wall for another 9.12 inches, which is why a 37.0 Hz tuning fits a 25.25 inch deep box.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eWhy this is a Professional build\u003c\/h4\u003e\n\u003cp\u003eEvery driver is run through the Performance Optimized wedge and down-fire before this chassis; the Professional box is where a driver lands when that smaller envelope, 30 inches wide and 18 inches deep with a triangular side port, cannot give it what it needs at its rated power. The Hurricane 15 does not fit that envelope at all: no tuning, width or depth inside it carries an 11.89 inch deep 15 inch driver at 3000 W.

Two windowed braces run front to back either side of the woofer, clearing the cutout by two and a half inches. The box ships dry: polyfill detunes a ported alignment. Inside the 35 by 18 Professional envelope for a single 15, 25.2 inches deep. 15.50 inch frame, flush in the outer baffle layer, 13.78 inch cutout, 11.89 inches of mounting depth. It ships as a parcel.\u003c\/p\u003e\n  \u003cp\u003eAmerican Bass publishes Fs, Qts, Vas, cone area and Xmax for the Hurricane 15 on its product page, but no overall frame diameter, no driver displacement and no Cms. The frame is taken as 15.50 inches, the larger of the nominal size plus half an inch and the 13.78 inch cutout plus a typical flange, so the baffle is never cut short; the 0.275 cubic feet of displacement is our estimate from comparable 15 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 25 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. The slot mouth runs 17.0 m\/s at the gate power against a 17 m\/s limit, so this is a box to run at its rating, not past it. American Bass does not publish the mounting hole locations for the Hurricane 15, so we cannot install the threaded inserts before it ships.

The frame is taken as 15.50 inches, the larger of the nominal size plus half an inch and the 13.97 inch cutout plus a typical flange, so the baffle is never cut short; the 0.182 cubic feet of displacement is our estimate from comparable 15 inch woofers and moves the tuning by a fraction of a hertz. American Bass does not say whether its 18 mm Xmax is one-way or peak to peak; we read it as one-way and keep power at its own rating. The product page gives no voice-coil label for this model; it is read as dual 4 ohm from the page's own part number, the pattern American Bass uses across the Titan line. Check your coil before wiring. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. American Bass does not publish the mounting hole locations for the Titan 15, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape.

The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape. You set the inserts when you mount the woofer, and this box ships with two kits, one per woofer.\u003c\/p\u003e\n  \u003cp\u003eBoth drivers share one chamber and one port rather than sitting in separate boxes, so the pair works against the whole volume and the port is sized for the pair rather than doubled. The port carries 21.9 square inches of area at 34.0 Hz, and the design power for the velocity and excursion checks is 720 W for the pair. Passband ripple holds at 0.81 dB across the tuning, with F3 at 36.4 Hz.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eWhat makes it Professional\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThree-layer baffle, flush mount\u003c\/h4\u003e\n\u003cp\u003eThree layers of 3\/4 inch Langboard Elite make a 2.25 inch\n    front.

The channel runs 6.00 inches along its wall and turns once along the back wall for another 20.90 inches, which is why a 34.0 Hz tuning fits a 11.50 inch deep box.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eWhy this is a Professional build\u003c\/h4\u003e\n\u003cp\u003eA single DX 10 also builds in the Performance Optimized ported wedge and ported down-fire, the smaller and cheaper single-driver boxes.

A windowed brace runs front to back beside the woofer, clearing the cutout by two and a half inches. The box ships dry: polyfill detunes a ported alignment. This is our dual 10 inch Professional envelope, built around the DX 10's own frame and mounting depth, with both woofers on one face and the port on the left.

Both drivers must be the same model and the same coil: mixing them puts unequal loads on one shared chamber, and neither driver sees the airspace it was picked for.

A windowed brace runs front to back beside the woofer, clearing the cutout by two and a half inches. The box ships dry: polyfill detunes a ported alignment.

Both drivers must be the same model and the same coil: mixing them puts unequal loads on one shared chamber, and neither driver sees the airspace it was picked for.

A windowed brace runs front to back beside the woofer, clearing the cutout by two and a half inches. The box ships dry: polyfill detunes a ported alignment.

It ships as a parcel.\u003c\/p\u003e\n  \u003cp\u003ePort mouth velocity peaks at 12.4 m\/s against the 17 m\/s point where a slot begins to chuff, and 18.0 m\/s in the channel, both measured at the pair's design power. Both drivers must be the same model and the same coil: mixing them puts unequal loads on one shared chamber, and neither driver sees the airspace it was picked for.
