Every Thiele-Small figure comes from AudioControl's own EPICX8 user manual. Both coil columns agree on Vas and resonance, and both reproduce their printed Qts; the D2 column is measured with the coils in series and the D4 in parallel, which is why their Re and Bl differ while their Re over Bl squared does not.\u003c\/p\u003e\n\u003cdiv class=\"po-highlight\"\u003e\u003cp\u003e0.40 cubic feet net on AudioControl's published figures: the EPICX8 D2 (dual 2 ohm) reads Qtc 0.791 with resonance at 59.4 Hz and half power at 53.7 Hz, and the EPICX8 D4 (dual 4 ohm) reads Qtc 0.782 with resonance at 60.0 Hz and half power at 54.8 Hz. One cabinet serves both coils. That is AudioControl's own recommended sealed size for this driver, 0.4 cubic feet, between their 0.25 minimum and 0.65 maximum.
