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

The GT2 2010, yes. The baffle is cut to 9.2 in, Audiomobile's published mounting hole, and the 4.25 in motor clears the raked back with 3.24 in to spare. Run two so the chambers match.

Any other 10, no. The airspace is set for the GT2'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 on Fs 27.5 Hz, Qts 0.61 and Vas 33.2 liters: Qtc 0.958, system resonance 43.2 Hz, half power 34.6 Hz. That is above maximally flat, a firm, punchy sealed box with a lift near resonance. A Qts of 0.61 is high enough that the flat box would need 3.4 cubic feet, far past what a trunk wedge should be, and Audiomobile itself recommends the GT2 vented, 0.75 to 1.25 cubic feet at 33 to 37 Hz; this is the sealed alternative.

Audiomobile publishes no displacement for the GT2 2010, so an estimated 0.088 cubic feet per driver is taken out of the net figure.

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; use 1.5 ohms only on an amplifier rated stable there. Confirm your amplifier's minimum stable impedance first.

The seat-side face carries a 20 degree rake that matches the lean of a factory rear seat back, so the cabinet sits flush against it and the cargo space in front stays usable. The baffle is the vertical trunk-lid-side face, so the drivers fire rearward into the trunk cavity.

The trunk acts as an acoustic extension for the sealed box, and the cabin adds real output below 50 Hz, so in-vehicle response runs deeper than the anechoic 34.6 Hz on this page.

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 with system resonance at 43.2 Hz. Above Qtc 0.707 F3 sits below fc, so the response carries a 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 with the gloss black acrylic baffle insert, one side-mounted pre-wired terminal cup to both positions, the polyfill lining already in place, 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 its recess, mark its holes, drill and press the inserts. The pair of GT2 2010 is purchased separately.
