This one is cut to the \u003cstrong\u003eAudiomobile GT2 2010\u003c\/strong\u003e, a 10 inch driver with 400 watts RMS of power handling, 11.9mm of one way Xmax, and only 4.25 inches of mounting depth. Those numbers are unusual together, and they are what make a cabinet this shallow possible in the first place.\u003c\/p\u003e\n\u003cp\u003eThe GT2 2010 asks for a small chamber. Audiomobile's own minimum sealed figure is 0.50 cubic feet. This enclosure gives each driver \u003cstrong\u003e0.60 cubic feet of net airspace in a common chamber\u003c\/strong\u003e, which sits comfortably inside the driver's working range while keeping the cabinet down to 8.5 inches of external height. The cutouts are 9.2 inches, matched to the driver's gasket ID, and the mounting pattern comes from the actual driver rather than a spec sheet.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"podf-section-alt\"\u003e\n\u003ch3\u003eWhy Down Fire\u003c\/h3\u003e\n\u003cp\u003eTurning the drivers toward the floor is not a styling decision.

Every panel meets on a machined joint rather than a butt seam, so the cabinet stays rigid and puts its energy into the drivers instead of the panels. Internal height under the top panel is 6.25 inches against the driver's 4.25 inch mounting depth, so the motors clear with room to breathe.\u003c\/p\u003e\n\u003ch3\u003eMounting Pattern Drawn In House\u003c\/h3\u003e\n\u003cp\u003eWe have the GT2 2010 in the shop. We measured it, built the bolt circle in CAD, and the nutsert locations and the cutout are machined in the same operation from the same origin on the router. \u003cstrong\u003eThe holes cannot drift relative to each other, because the machine never re-references between them.\u003c\/strong\u003e Threaded inserts are installed and 8\/32 machine screws are supplied, so the drivers can come out and go back in as many times as the build requires.\u003c\/p\u003e\n\u003ch3\u003eWiring and Damping\u003c\/h3\u003e\n\u003cp\u003eThe Proline X ABS and carbon fiber composite terminal cup is \u003cstrong\u003eside mounted\u003c\/strong\u003e, which keeps the connection accessible with the enclosure sitting on its feet.

0.61, which means it cannot reach a textbook 0.707 Qtc in any enclosure that fits in a vehicle. You would need 3.41 cu ft per driver. At 0.60 cu ft this alignment lands at Qtc 1.048, which puts a roughly 1.5 dB lift around 47 Hz and an anechoic F3 of 36.4 Hz. That is an impact alignment, not a flat one. Loaded into a trunk or cargo floor and firing down, cabin gain fills in below the knee and the result is a punchy, high output system. If you want a flat sealed alignment above all else, this is not the driver or the enclosure for it.\u003c\/p\u003e\u003c\/div\u003e\n\u003cp\u003eRun your own numbers with the \u003ca href=\"\/pages\/sealed-box-calculator\"\u003eSealed Box Calculator\u003c\/a\u003e.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"podf-section\"\u003e\n\u003cp\u003eFull dimensions, cutout, mounting depth, and hardware details are listed under the \u003cstrong\u003eEnclosures\u003c\/strong\u003e tab.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"podf-cta\"\u003e\n\u003ch3\u003eCut for the GT2 2010.
