Every figure comes from the Thiele-Small table Skar prints on its EVL-12 product page. Skar publishes no driver displacement, so 0.129 cubic feet is our estimate from comparable 12 inch woofers, and it moves the net figure by a few hundredths at most. Worth knowing: the D4's printed Qts of 0.46 sits 9 percent from the 0.50 its own Qes and Qms reproduce; the D2's printed Qts of 0.42 sits 10 percent from the 0.46 its own Qes and Qms reproduce, so treat the Qtc as good to a few hundredths.\u003c\/p\u003e\n\u003cdiv class=\"po-highlight\"\u003e\u003cp\u003e0.79 cubic feet net per chamber is the smallest box that carries the EVL-12 frame, already under the Butterworth volume on the D4 figures, Fs 32.6 Hz, Qts 0.46 and Vas 18.2 liters: Qtc 0.619, half power at 51.0 Hz. One cabinet serves both coils: the EVL-12 D4 reads Qtc 0.619 with half power at 51.0 Hz, and the D2 reads Qtc 0.572 at 56.5 Hz.
