I have 4 12" SI BMs. They are slightly used. They are in very good condition both mechanically and cosmetically. They are all Dual 4 ohm. SI recommends 1 cube sealed or 2 cubes ported tuned to 34 hz for each one.
Trades:
Only interested in 2 Dual 2 ohm 12s - RE MTs, IA DPs, FI BTLs, AQ HD3©s, DD 9512s.
Results from Great 12 Challenge:
Ported Enclosure:
Average SPL: 126.65 dB
dB/Watt: 0.2533 dB
Driver Notes:
* Build quality is excellent
* SPL box testing was limited to 1300 watts, due to the woofer approaching thermal limits
* Woofer should be ok with musical content over RMS rating (under 900 watts).
* Woofer has a strong midbass presence
