sundownz Posted October 7, 2008 Report Share Posted October 7, 2008 I bought out all of the QC failed SI BM 10s (old models) and re-built them with several changes: 1) Slightly longer flat-wound coil (original was round wire) - USA made coils 2) Narrower / Taller Surround 3) Tied down tinsel leads Measured T/S Specs (coils in series): RE: 6.89 ohms Z: 8 ohms Fs: 27.2 Hz Qes: 0.56 Qms: 3.32 Qts: 0.48 Le: 2.8 mH Vas: 31.1 L BL: 16.2 NA Mms: 124 grams Power: 400 watts RMS 0.95 ft^3 SEALED BOX - F3 of 41 Hz 1.5 ft^3 ported tuned to 30 - 35 Hz for high output I have about 40 of these... $125 shipped in the continental USA for one $240 shipped in the continental USA for two $440 shipped in the continental USA for four Ask about more than that! These are blow-out items and sold with no warranty beyond a no DOA guarantee. I can built re-cones for them for a while as I did get about 25 sets of extra parts! They are pretty tough with a 2.5" diameter flat coil, though Nice sounding drivers. - Jacob Fuller - Owner, Sundown Audio - Sundown Audio on FACEBOOK - Please DO NOT PM ME -- use my email address -- [email protected] Link to comment Share on other sites More sharing options...
