Professional Series Ported 12" Enclosure American Bass DX 12 · Single 12" Ported enclosure

Sealed, the DX 12 needs 3.77 cubic feet net to reach a Qtc of 0.707. Vented, it trades that for deeper extension. The slot is gated at 360 W, 1.2 times American Bass's rating: the channel runs 17.2 m/s and the mouth 8.9, and the cone peaks at 6.4 of its 11 mm with the subsonic filter in place. 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.

The DX 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 360 W. It carries a 2 year warranty, against 1 year on the Performance Optimized lines.

American Bass does not publish the mounting hole locations for the DX 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.

Yes, at 27 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 American Bass DX 12 at 62 percent of its usable travel at 360 W.

Not one we can show you. We do not build a sealed enclosure for the American Bass DX 12 and American Bass publish no sealed volume for it, so the Performance Graphs tab carries no ported-versus-sealed chart: the only sealed box left to plot would be this cabinet stuffed and sealed, which nobody would build, and a comparison against it would tell you nothing you could buy. What a vented box gives up is the region below tuning, where the cone unloads and the 27 Hz subsonic filter takes over; around 34.0 Hz the vent carries the load and cone travel drops to its minimum, which no sealed alignment can do.

It is a vertical slot beside the woofer, the full height of the cavity, 1.25 inches wide and 18.1 square inches. It runs 5.75 inches to the back wall and turns once along it for 11.10 inches; the fold costs about 1.5 Hz and the port is cut for it. The channel runs at 17.2 metres per second at 360 W, 49 percent of its turbulence limit, and the mouth edges carry a 1/2 inch roundover so the air leaves the face at 8.9 metres per second against the 17 metres per second threshold where a slot starts to chuff.

50 lb, 32.00" W x 16.00" H x 10.75" D external. Every Professional cabinet is priced the same way, by its size: this one is 3.19 cubic feet outside. Delivery to the 48 states is inside the price; it ships as a 50 lb parcel and checkout adds nothing. Do not add polyfill; it ships dry on purpose.

No. This is an enclosure only, cut for the American Bass DX 12 specifically: the 11.100 inch cutout, the 5.600 inch mounting depth allowance and the 1.48 cubic foot alignment all come from American Bass's published parameters. It fits both coil versions; the alignment published here is the S4. Bring your own driver.
