Every figure comes from JL Audio's published 12W7AE-3 parameters, and they hold together: Qes and Qms reproduce the printed Qts, and the 217 g moving mass and 0.158 mm\/N compliance reproduce the 27.2 Hz resonance and 66.0 liter Vas.\u003c\/p\u003e\n\u003cdiv class=\"po-highlight\"\u003e\u003cp\u003e1.375 cubic feet net on JL's published Fs 27.2 Hz, Qts 0.482 and Vas 66.0 liters: Qtc 0.791, system resonance 44.7 Hz, half power 40.4 Hz.

JL's own sealed recommendation for the 12W7AE-3 is 1.375 cubic feet net, and this cabinet is built to it.
