Skar does not say how the Xmax was measured, so we size port and power against it rather than past it. Also: Skar publishes no outside frame diameter for its 15s; 15.50 inches is our estimate from the 14.00 inch cutout, and the baffle is sized with margin for it. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement.

This cabinet gives it 1.96 cubic feet net behind a 2.25 inch three-layer baffle, vented at 33.0 Hz through a 34.4 square inch slot beside the woofer, for an anechoic F3 of 27.7 Hz in a 30 by 14 by 17.5 inch front-firing box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThreaded insert kit ships with this box.\u003c\/strong\u003e Skar Audio does not publish the mounting hole locations for the EVL-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 EVL-10 needs 0.55 cubic feet net to reach a Qtc of 0.707. Vented, it trades that for deeper extension. The slot is gated at 1200 W, 1.2 times Skar's rating: the channel runs 22.8 m\/s and the mouth 15.5, and the cone peaks at 11.7 of its 23.5 mm with the subsonic filter in place. Skar's own ported recommendation is 1.75 to 2.00 cubic feet at 40 Hz, before driver and port displacement.\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 11.00 inches along its wall and turns once along the back wall for another 16.21 inches, which is why a 33.0 Hz tuning fits a 17.50 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\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 EVL-10 did not clear the port gate there. The calmest wedge port that fits that envelope is 18.4 square inches at 27.5 by 10.88 by 15.79 inches, and its mouth runs 21.4 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 631 W.

Some of it is softer than it looks. Skar gives no driver displacement anywhere, so 0.092 cubic feet is our estimate from comparable 11 inch woofers; it moves the tuning by a fraction of a hertz. Skar does not say how the Xmax was measured, so we size port and power against it rather than past it. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement. Skar Audio does not publish the mounting hole locations for the EVL-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.

This cabinet gives it 2.31 cubic feet net behind a 2.25 inch three-layer baffle, vented at 34.5 Hz through a 45.4 square inch slot beside the woofer, for an anechoic F3 of 30.7 Hz in a 36 by 18 by 14.2 inch front-firing box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThreaded insert kit ships with this box.\u003c\/strong\u003e Skar Audio does not publish the mounting hole locations for the EVL-15, so we cannot install the threaded inserts before it ships.

Some of it is softer than it looks. Skar gives no driver displacement anywhere, so 0.204 cubic feet is our estimate from comparable 15 inch woofers; it moves the tuning by a fraction of a hertz. Skar does not say how the Xmax was measured, so we size port and power against it rather than past it. Also: Skar publishes no outside frame diameter for its 15s; 15.50 inches is our estimate from the 14.00 inch cutout, and the baffle is sized with margin for it. Tuning includes a 1.5 Hz fold loss that is an estimate, not a bench measurement.

It is 7.61 inches deep, which matters on a down fire, where the motor rises into the cabinet. Every figure comes from the Thiele-Small table Skar prints on its EVL-12 product page. Skar publishes no driver displacement, so 0.129 cubic feet is our estimate from comparable 12 inch woofers, and it moves the net figure by a few hundredths at most. Worth knowing: the D4's printed Qts of 0.46 sits 9 percent from the 0.50 its own Qes and Qms reproduce; the D2's printed Qts of 0.42 sits 10 percent from the 0.46 its own Qes and Qms reproduce, so treat the Qtc as good to a few hundredths.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003eNet Volume, Not Gross\u003c\/h3\u003e\n\u003cp\u003eWe build this cabinet at \u003cstrong\u003e1.33 cubic feet net\u003c\/strong\u003e, out of 1.47 gross after the brace and an estimated 0.129 cubic foot driver displacement.

Skar publishes no outside frame diameter for its 15s, so the flush recess is sized to 15.50 in with margin. The rear panel rakes 20 degrees, so the cavity deepens from 12.21 in at the top to 18.76 in at the base, and the 8.54 in motor clears it with 3.56 in to spare. Skar prints no bolt circle for the EVL-15, so the baffle ships undrilled with a threaded insert kit and stainless machine screws: set the driver in the recess, mark its holes, drill, press the inserts and bolt it down.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-section\"\u003e\n\u003ch2\u003eWhat the Numbers Rest On\u003c\/h2\u003e\n\u003cdiv class=\"po-grid\"\u003e\n\u003cdiv class=\"po-card\"\u003e\n\u003ch4\u003eLangboard Elite MDF\u003c\/h4\u003e\n\u003cp\u003ePremium 3\/4 in MDF throughout.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-card\"\u003e\n\u003ch4\u003eV-Groove and Dado Joinery\u003c\/h4\u003e\n\u003cp\u003eCNC cut V-grooves at every panel intersection, sides and brace seated in dados.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-card\"\u003e\n\u003ch4\u003eDouble-Layer 1.5\" Front Baffle\u003c\/h4\u003e\n\u003cp\u003eTwo bonded 3\/4 in MDF sheets at the driver face, the outer layer machined as a flush recess.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-card\"\u003e\n\u003ch4\u003eSkar's Published Parameters\u003c\/h4\u003e\n\u003cp\u003eD2: Fs 35.0 Hz, Qts 0.63, Qes 0.73, Qms 4.60, Vas 46.0 L, Sd 779 cm2, Cms 0.053 mm\/N, Bl 21.0 N\/A, Mms 387 g.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-section\"\u003e\n\u003ch2\u003eWiring the Skar EVL-15 to Your Amplifier\u003c\/h2\u003e\n\u003cp\u003eThe EVL-15 D2 wires to 4 ohms with its coils in series or 1 ohm in parallel.
