Professional Series Ported Dual 12" Enclosure JL Audio 12W6v3 · Dual 12" Ported enclosure

Both 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 36.2 square inches of area at 32.0 Hz, and the design power for the velocity and excursion checks is 1440 W for the pair. Passband ripple holds at 1.48 dB across the tuning, with F3 at 33.6 Hz. Tuning is chosen for in-car response rather than an anechoic curve: a vehicle adds roughly 12 dB per octave below about 45 Hz, and this tuning is where that sum comes out flattest across 25 to 60 Hz.

A single 12W6v3 also builds in the Performance Optimized ported wedge, the smaller and cheaper single-driver box. A pair takes this Professional cabinet: one shared chamber on a 2.25 inch three-layer baffle with both woofers flush in the outer layer, and a slot port gated at 1440 W for the pair. It carries a 2 year warranty, against 1 year on the Performance Optimized lines.

Threaded inserts pressed into the baffle on the published 11.860 inch bolt circle, stainless machine screws included. The inserts are in the baffle when it arrives; the machine screws are in the terminal cup bag.

Yes, at 25 Hz, 24 dB per octave. Below tuning a vented box stops loading the cone and excursion runs away toward DC. With the filter in place this cabinet puts the JL Audio 12W6v3 at 45 percent of its usable travel at 1440 W.

The two alignments converge at the bottom of the band on this driver rather than crossing cleanly, so there is no meaningful subsonic advantage either way. Above 25 Hz the vent is the louder of the two for the same power. The Performance Graphs tab plots this cabinet, 2.31 cubic feet vented at 32.0 Hz, against the 1.00 cu ft sealed wedge we build for this driver (PO 12-S W W6 BB) per driver, 2.00 cu ft for the pair, so you can judge it yourself.

It is a vertical slot beside the woofer, the full height of the cavity, 2.50 inches wide and 36.2 square inches. It runs 6.75 inches to the back wall and turns once along it for 18.62 inches; the fold costs about 1.5 Hz and the port is cut for it. The channel runs at 20.7 metres per second at 1440 W, 47 percent of its turbulence limit, and the mouth edges carry a 1/2 inch roundover so the air leaves the face at 13.9 metres per second against the 17 metres per second threshold where a slot starts to chuff.

70 lb packed, 42.00" W x 16.00" H x 13.00" D external. This cabinet is 5.06 cubic feet outside. Delivery to the 48 states is inside the price; it ships as a 70 lb parcel and checkout adds nothing. Do not add polyfill; it ships dry on purpose.

No. This is an enclosure only, cut for the JL Audio 12W6v3 specifically: the 11.024 inch cutout, the 7.520 inch mounting depth allowance and the 2.31 cubic foot alignment all come from JL Audio's published parameters. It fits both coil versions; the alignment published here is the Dual 4 Ohm. Bring your own driver.
