Every Thiele-Small figure comes from JL's own owner's manual for the 12W1v3, both columns, and the table holds together: each column reproduces its own printed Qts, the two versions agree on Vas and resonance, and JL's own 1.10 cubic foot sealed box reproduces JL's printed Qtc of 0.950 and 0.934.\u003c\/p\u003e\n\u003cdiv class=\"po-highlight\"\u003e\u003cp\u003e1.10 cubic feet net on JL's published figures: the 2 ohm version reads Qtc 0.948 with resonance at 48.3 Hz and half power at 39.0 Hz, and the 4 ohm version reads Qtc 0.934 with resonance at 48.8 Hz and half power at 39.6 Hz. One cabinet serves both versions. The volume is JL's own recommended sealed airspace for the 12W1v3, 1.10 cubic feet per driver, and on JL's published parameters this chamber reproduces JL's printed Qtc, fc and F3 for both versions.
