Performance Optimized Down Fire Sealed Dual 10" Enclosure Audiomobile GT2 2010 · Dual 10" Sealed enclosure

The GT2 2010, yes, in the 3 ohm version. The baffle is cut to 9.2 in, Audiomobile's published mounting hole, under the 10.65 in frame. The 4.25 inch motor clears the cabinet with 5.75 inch to spare. Run a matched pair so the chambers match.

Any other 10, no. The airspace is engineered around the GT2 2010's own Qts and Vas, and a different woofer that happened to drop into the hole would not see the alignment printed on this page.

0.80 cubic feet net per chamber: the GT2 2010 reads Qtc 0.958 with resonance at 43.2 Hz and half power at 34.6 Hz. That is above maximally flat: a firm, punchy sealed box with a lift near resonance.

Cabinet gain in a vehicle lifts the bottom end further, so in the car this reads deeper than the anechoic figures.

Audiomobile rates the GT2 2010 at 400 watts RMS per driver, so target 280 to 400 watts RMS per driver at the final load.

Each GT2 2010 has a single 3 ohm coil (2.8 ohms DC). Two in parallel present 1.5 ohms, two in series 6 ohms. Confirm your amplifier's minimum stable impedance first.

The cabinet is 10.75 inches tall measured in the down fire position, and that figure excludes the standoffs. The standoffs hold 1.75 inches under the baffle, so plan your space around a finished stack of roughly 12.50 inches.

The footprint is the standard Performance Optimized down fire platform, 30.00 inches wide by 15.00 deep. Height is the only dimension solved to the driver.

Two drivers sharing one sealed volume load each other: each driver's compression stroke becomes the pressure the other works against, which blurs the alignment either would have alone. A bonded full-height 3/4 inch divider gives each driver its own 0.80 cubic feet and its own polyfill.

It also means a failure in one driver does not unload the other, and the alignment on this page is the alignment in each chamber, not an average across a shared box.

Anechoic F3 is 34.6 Hz per chamber. Above Qtc 0.707 F3 sits below fc, so the response carries a small lift near resonance before it rolls off.

Those figures exclude cabin gain. In a car the cabin's transfer function adds real output below 50 Hz, so in-vehicle response runs deeper than the numbers above.

No. Polyfill is already installed in both chambers as a light wall lining to control internal reflections, and the quantity is chosen so it does not change the acoustic volume.

Do not add more. Packing a sealed box with fill makes it behave as though it were larger, which walks the alignment away from the 0.80 cubic feet per chamber this cabinet was built to.

No driver. This is an enclosure only. You receive the cabinet finished in plush black carpet, one side-mounted pre-wired terminal cup to both positions, the polyfill lining already in place, the standoffs, and a threaded insert kit with stainless machine screws.

The inserts ship loose on purpose: Audiomobile prints no bolt circle for the GT2 2010, so you set the driver in the recess, mark its holes, drill and press the inserts. The pair of Audiomobile GT2 2010 is purchased separately, and the cabinet is cut direct fit to it, not a general purpose 10 inch box.
