is the 13.5 inch of JL Audio's W7AE line: 23.5 Hz, a Qts of 0.448, 104.3 litres of Vas, dual 1.5 ohm coils rated 1500 W RMS together and 32 mm of one-way excursion from a 10.5 inch deep motor. JL recommends a 2.375 cubic foot ported box tuned to 34.6 Hz, and that is what this cabinet is: 2.40 cubic feet net behind a 2.25 inch three-layer baffle, tuned to 34.6 Hz through a 43.5 square inch slot beside the woofer, for an anechoic F3 of 31.1 Hz in a 34 by 16 by 16.4 inch front-firing box.\u003c\/p\u003e\n \u003cp\u003eJL's own ported design uses a 2.25 by 14.5 inch slot, about 32.6 square inches. This one keeps JL's volume and tuning and opens the slot to 43.5 square inches: gated at 1800 W, 1.2 times JL's rating, the channel runs 22.5 m\/s against a 30.6 gate and the mouth 15.8 m\/s, and the cone peaks at 12.1 of its 32 mm with the subsonic filter in place. Sealed, JL's 1.875 cubic foot box is a Qtc of 0.77 with an F3 of 37.4 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 calmest wedge port that fits that envelope is 16.9 square inches at 25.5 by 12.12 by 17.95 inches, and its mouth runs 22.8 metres per second at 1500 W against the 17 metres per second line where a port starts to chuff.

Those are twelve inch numbers on an eight inch cone, and they belong to JL's flagship motor. No other eight in this programme is within reach of it, and few of the tens are either.\u003c\/p\u003e\n \u003cp\u003eGiven 1.18 cubic feet vented at 34.0 Hz it reaches an anechoic F3 of 28.7 Hz and holds 4.0 dB of in-car spread, the flattest in-car result of JL's three eights. A 0.61 Qts with 17.4 litres of Vas is a heavily damped motor, and heavy damping is what lets an eight this powerful stay controlled in a vented box rather than becoming a one-note one.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n \u003ch3\u003eThe port is the product\u003c\/h3\u003e\n \u003cp\u003eA ported cabinet is easy to get wrong and the failure is audible. This one uses an\n L-wrap slot port: a single folded wall running down the long side of the box past the\n woofer ring, turning once through a faceted 90 degree bend, and opening through a\n chamfered corner. One wall, one bend, 29.59 inches of centreline path.\u003c\/p\u003e\n \u003cp\u003eThe channel is 3.00 inches wide by 6.25 tall, 18.8 square inches, and it exits\n through a 26.5 square inch mouth. Air leaves at 14.6 metres per second at the tuning\n frequency, against the 17.0 metre per second threshold where a slot port starts to\n chuff. The bend is faceted rather than square because the inner corner of a 90 degree\n turn is where flow separates, and a sharp corner there is what you hear.\u003c\/p\u003e\n \u003cdiv class=\"df-highlight\"\u003e\n \u003cp\u003e\u003cstrong\u003eThis enclosure ships dry.\u003c\/strong\u003e Polyfill goes in every sealed Proline X\n cabinet we build. It does not go in this one. Damping material in a vented box\n changes the effective volume the port is tuned against, which moves the tuning\n frequency away from the 34.0 Hz the port length was cut for. Adding it does not make\n a ported box sound like a bigger ported box; it makes it a mistuned one.\u003c\/p\u003e\n \u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n \u003ch3\u003eRun a subsonic filter\u003c\/h3\u003e\n \u003cp\u003eThis is not optional advice on a vented enclosure. Below tuning the port stops\n loading the cone and excursion climbs without limit toward DC, so a 27 Hz high-pass at\n 24 dB per octave is part of the specification rather than a refinement of it. Set it\n and the same cabinet takes substantially more power for the same cone travel. Leave it\n out and the driver runs out of suspension on material you cannot hear.\u003c\/p\u003e\n \u003cp\u003eEvery wattage on the Performance Graphs tab is a mechanical limit, not an electrical\n one: it is the power at which the cone reaches the end of its linear travel in this\n box.

Frame, mounting hole, mounting depth, bolt circle and displacement are all JL's own figures; nothing on this page is an estimate. At 6.83 inches the motor is deep for an 8, and it is the reason the Performance Optimized ported wedge cannot hold this driver at its 11.75 inch height: the port that fits runs too fast.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n \u003ch3\u003eThe numbers to respect\u003c\/h3\u003e\n \n \u003cp\u003eSet a 27 Hz subsonic filter, 24 dB per octave.

this driver is vented at 34.0 Hz\u003c\/h3\u003e\n \u003cp\u003eJL recommends 1.5 cubic feet ported for the 10W7AE-3, and this down-fire gives it 1.47 net, vented at 34.0 Hz for an anechoic F3 of 30.2 Hz and 2.8 dB of in-car spread from 25 to 60 Hz. It is the smaller and cheaper of the two ported boxes we build for this driver; the Professional cabinet is the other.\u003c\/p\u003e\n \u003cp\u003eThe 10W7AE-3 is a 0.537 Qts driver with 36.1 litres of Vas and 23 mm of one-way travel, rated 750 W. That is a motor that wants a vent, and the down-fire's full 31 inch length lets the slot run long enough to tune it low without growing the box past 8.5 inches tall.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n \u003ch3\u003eThe port is the product\u003c\/h3\u003e\n \u003cp\u003eA ported cabinet is easy to get wrong and the failure is audible. This one uses an\n L-wrap slot port: a single folded wall running down the long side of the box past the\n woofer ring, turning once through a faceted 90 degree bend, and opening through a\n chamfered corner. One wall, one bend, 28.22 inches of centreline path.\u003c\/p\u003e\n \u003cp\u003eThe channel is 3.25 inches wide by 6.99 tall, 22.7 square inches, and it exits\n through a 29.7 square inch mouth. Air leaves at 16.7 metres per second at the tuning\n frequency, against the 17.0 metre per second threshold where a slot port starts to\n chuff. The bend is faceted rather than square because the inner corner of a 90 degree\n turn is where flow separates, and a sharp corner there is what you hear.\u003c\/p\u003e\n \u003cdiv class=\"df-highlight\"\u003e\n \u003cp\u003e\u003cstrong\u003eThis enclosure ships dry.\u003c\/strong\u003e Polyfill goes in every sealed Proline X\n cabinet we build. It does not go in this one. Damping material in a vented box\n changes the effective volume the port is tuned against, which moves the tuning\n frequency away from the 34.0 Hz the port length was cut for. Adding it does not make\n a ported box sound like a bigger ported box; it makes it a mistuned one.\u003c\/p\u003e\n \u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n \u003ch3\u003eRun a subsonic filter\u003c\/h3\u003e\n \u003cp\u003eThis is not optional advice on a vented enclosure. Below tuning the port stops\n loading the cone and excursion climbs without limit toward DC, so a 27 Hz high-pass at\n 24 dB per octave is part of the specification rather than a refinement of it. Set it\n and the same cabinet takes substantially more power for the same cone travel. Leave it\n out and the driver runs out of suspension on material you cannot hear.\u003c\/p\u003e\n \u003cp\u003eEvery wattage on the Performance Graphs tab is a mechanical limit, not an electrical\n one: it is the power at which the cone reaches the end of its linear travel in this\n box. What the voice coil can dissipate as heat is a separate ceiling set by JL Audio, not by\n the cabinet.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n \u003ch3\u003eCut for this driver, not for a catalogue\u003c\/h3\u003e\n \u003cdiv class=\"df-grid\"\u003e\n \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eMounting\u003c\/h4\u003e\n\u003cp\u003eCut to JL Audio's published 8.740 inch cutout with a\n 11.500 inch ring bonded under the baffle.
