Every figure comes from Audiomobile's own Encore Series specification sheet, the Klippel data measured with the two 4 ohm coils in parallel, which reproduces its own moving mass and compliance.

The rear panel rakes 20 degrees, so the cavity deepens from 6.34 in at the top to 11.80 in at the base, and the 4.9 in motor clears it with 0.75 in to spare above its top edge. The cosmetic recess is cut to Audiomobile's published 12.65 in frame. Audiomobile publishes no mounting hole locations for the Encore, 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\u003eAudiomobile's Own Sheet\u003c\/h4\u003e\n\u003cp\u003eFs 32.0 Hz, Qts 0.518, Qes 0.538, Qms 13.424, Vas 30.12 L, Sd 498.76 cm2, Mms 289.48 g, Cms 0.086 mm\/N, Bl 13.5 T-m, coils in parallel.
