Every Thiele-Small figure comes from Dayton's own spec sheet, and it holds together: Qes and Qms reproduce the printed Qts, the moving mass matches the published Vas and cone area, and Qes follows from Bl, Re and Mms. Dayton's product page prints the RSS315HF-4's Bl as 1 Tm; the spec sheet's 13.99 Tm is used.\u003c\/p\u003e\n\u003cdiv class=\"po-highlight\"\u003e\u003cp\u003e1.75 cubic feet net on Dayton's published figures: the RSS315HF-4 (single 4 ohm) reads Qtc 0.640 with resonance at 39.7 Hz and half power at 44.3 Hz, and the RSS315HFA-8 (single 8 ohm) reads Qtc 0.774 with resonance at 38.2 Hz and half power at 35.2 Hz. One cabinet serves both coils, built to the volume that keeps both closest to maximally flat.
