It carries the same deep motor as the 10 inch KXE, 6.77 inches of mounting depth on a 12.52 inch frame. Every figure comes from Focal's own SUB 30 KXE technical sheet. One number on it is soft: Focal prints 50 liters of Vas and draws its closed-box response chart on it, while its own compliance implies 52.5 and the published moving mass and resonance nearer 58 liters. At 58 the Qtc in this cabinet would read 0.74 instead of 0.71, so treat the alignment as a range a few hundredths wide.\u003c\/p\u003e\n\u003cdiv class=\"po-highlight\"\u003e\u003cp\u003e1.30 cubic feet net is the Butterworth volume on Focal's published Fs 29 Hz, Qts 0.46 and Vas 50 liters: Qtc 0.707, maximally flat, with system resonance and half power both at 44.6 Hz.

Loudspeaker Database lists a 284 mm cutout, but Focal's own drawing puts the basket at 284.2 mm just under the flange, which a 284 mm hole would not pass; the 285 mm cut clears it and the 318 mm frame still covers it with margin. The rear panel rakes 20 degrees, so the cavity deepens from 8.21 in at the top to 13.67 in at the base, and the 6.77 in motor clears it with 0.75 in to spare. Focal's drawing shows eight mounting holes but prints no bolt circle, 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\u003eFocal's Own Sheet\u003c\/h4\u003e\n\u003cp\u003eFs 29 Hz, Qts 0.46, Qes 0.49, Qms 6.1, Vas 50 L, Sd 502 cm2, Mms 183 g, Cms 0.15 mm\/N, Bl 21.3 N\/A, Re 6.4 ohm with the coils in series.
