Audiomobile GT2 2010 10 inch Subwoofer

Audiomobile designed the GT2 series around vented enclosures in the 0.75 to 1.25 ft³ range tuned in the mid-30s. A 1.20 ft³ chamber tuned to 37Hz is the textbook alignment for this driver. Audiomobile publishes a 0.50 ft³ (14 L) sealed minimum, so 0.50 to 0.75 ft³ is the sealed window, but sealed alignment does not represent the GT2's design intent and you will not get the output character the driver was engineered for.

Audiomobile designed the GT2 2010 with a 3-ohm voice coil (2.8Ω DCR actual) to optimize the relationship between voice coil mass, motor force, and amplifier loading. The 3-ohm nominal value is not a manufacturing variance, it is the engineered impedance. One driver presents a 3-ohm load. Two drivers parallel produce 1.5 ohms, two drivers series produce 6 ohms. Plan your amplifier selection around those values rather than standard 2-ohm or 4-ohm car audio impedances.

Any monoblock or full-range amplifier rated for 3-ohm operation works. Power output will fall between the amplifier's rated 2-ohm and 4-ohm figures. Target an amplifier with 300 to 500W RMS at 4 ohms to match the GT2's 400W RMS power handling at the 3-ohm load. Check the amplifier's published 3-ohm or 2-ohm rating to verify.

A 1-ohm stable monoblock in the 800W to 1000W RMS range, wired parallel for a 1.5 ohm load. If your amplifier is not 1-ohm stable, wire the drivers in series for a 6 ohm load and accept reduced power output. Two GT2 2010s wired parallel on a non-1-ohm-stable amplifier will trigger the amplifier's protection circuit and may damage either the amplifier or the drivers.

The 4.25" mounting depth is one of the shallowest on the market for a 10" subwoofer rated at 400W RMS. It fits most behind-seat truck enclosures and shallow trunk floors that a standard 5" or 6" deep 10" driver will not clear. Measure your available depth from baffle to vehicle structure before ordering, and verify the cutout diameter of your enclosure matches the GT2's 9.2" cutout.

Yes, in a 0.50 to 0.75 ft³ sealed chamber. Audiomobile publishes 0.50 ft³ (14 L) as the minimum sealed volume and calls for half a pound of fiberfill in the chamber. The sealed alignment produces a Q in the 0.7 range with rolled-off low-end response below 40Hz. Audiomobile designed the GT2 series for vented operation, so sealed operation works but does not produce the output level or low-frequency extension the driver is engineered to deliver. If you have the space, build vented.

The 11.9mm Xmax figure published for the GT2 2010 is one-way linear excursion, the displacement the cone can travel before the voice coil begins to leave the linear range of the motor's magnetic gap. Xmech (mechanical excursion limit) is the absolute maximum travel before the suspension or motor structure restricts movement. Audiomobile publishes 1.5 inches peak-to-peak for the GT2 2010, which is 19.05mm one-way against the 11.9mm one-way Xmax. Running within Xmax keeps the driver in its linear operating range and produces clean output.

The GT2 2010 is a vented-application SQ and daily-driver subwoofer rather than an SPL competition driver. It prioritizes linearity, musical character, and low-profile fitment over maximum peak SPL output. For SPL-specific applications you want a deeper driver with a more aggressive motor structure. For musical bass in a compact ported enclosure where depth is constrained, the GT2 is engineered for exactly this application.
