Every Thiele-Small figure comes from Ampere's own published table for the AA-3.0 15, and the table holds together: the moving mass and resonance reproduce the published Vas on a cone area in class for a 15 inch driver. Ampere prints no cone area for this driver, so the 754 square centimeters used for excursion and output figures is derived from Ampere's own Vas, resonance and moving mass.\u003c\/p\u003e\n\u003cdiv class=\"po-highlight\"\u003e\u003cp\u003e1.60 cubic feet net on Ampere's published figures: the dual 2 ohm reads Qtc 0.644 with resonance at 40.7 Hz and half power at 45.1 Hz. That is a slightly over-damped alignment: a gentle, early rolloff and tight transients rather than a flat top. This cabinet is listed for the AA-3.0 15 dual 2 ohm only. Ampere's dual 1 ohm version reads Qtc 0.51 in the same airspace, too damped to sound right sealed, so it is not offered in this enclosure.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-section\"\u003e\n\u003ch2\u003eTrunk-Load Wedge Design Explained\u003c\/h2\u003e\n\u003cp\u003eThe driver mounts on the vertical trunk-lid-side face and fires rearward into the trunk cavity.\u003c\/p\u003e\n\u003cdiv class=\"po-grid\"\u003e\n\u003cdiv class=\"po-card\"\u003e\n\u003ch4\u003eSeat-Side Face Matches Seat Lean\u003c\/h4\u003e\n\u003cp\u003eAngled face matches the roughly 20 degree factory seat lean.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-card\"\u003e\n\u003ch4\u003eTrunk-Lid-Side Face Fires the Woofer\u003c\/h4\u003e\n\u003cp\u003eVertical baffle, cone firing rearward into the trunk cavity.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-card\"\u003e\n\u003ch4\u003eTrunk Cavity Loading\u003c\/h4\u003e\n\u003cp\u003eThe trunk acts as an acoustic extension for a smoother presentation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-card\"\u003e\n\u003ch4\u003ePreserves Trunk Cargo Space\u003c\/h4\u003e\n\u003cp\u003eThe wedge tucks against the seat back and the space in front stays usable.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-section\"\u003e\n\u003ch2\u003eEngineered for the Ampere Audio AA-3.0 15\u003c\/h2\u003e\n\u003cp\u003eAnechoic half power lands at 45.1 Hz, before any cabin gain.

The rear panel rakes 20 degrees, so the cavity deepens from 12.36 in at the top to 18.91 in at the base, and the 11.50 in motor clears it with 0.75 in to spare. Ampere prints no bolt circle for the AA-3.0 15, so the baffle ships undrilled with a threaded insert kit and stainless machine screws: set the driver in the recess, mark its holes, drill, press the inserts and bolt it down.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-section\"\u003e\n\u003ch2\u003eWhat the Numbers Rest On\u003c\/h2\u003e\n\u003cdiv class=\"po-grid\"\u003e\n\u003cdiv class=\"po-card\"\u003e\n\u003ch4\u003eLangboard Elite MDF\u003c\/h4\u003e\n\u003cp\u003ePremium 3\/4 in MDF throughout.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-card\"\u003e\n\u003ch4\u003eV-Groove and Dado Joinery\u003c\/h4\u003e\n\u003cp\u003eCNC cut V-grooves at every panel intersection, sides and brace seated in dados.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-card\"\u003e\n\u003ch4\u003eDouble-Layer 1.5\" Front Baffle\u003c\/h4\u003e\n\u003cp\u003eTwo bonded 3\/4 in MDF sheets at the driver face, the outer layer machined as a flush recess.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-card\"\u003e\n\u003ch4\u003eAmpere's Published Parameters\u003c\/h4\u003e\n\u003cp\u003edual 2 ohm: Fs 29.1 Hz, Qts 0.46, Qes 0.51, Qms 4.4, Vas 43.3 L, Mms 557.9 g, Bl 26.8 N\/A, Re 3.6 ohm.
