Hey, KGV,
How'd the Bassis work out for ya?
I've been working on a 1X12" 600W and a 2X12" 1200W ported subs and a 2X12" 2400W sealed, EQ'd and a 2X15" 3KW sealed, EQ'd and setting up blind listening tests and a host of other objective tests to try to nail the subjective differences.
Love your low end rig!! Some day I'll convince you to dump the adcoms and try QSC RMX series.
BTW, I run 4 Rocket RS-750 Sigs and dual RS 200 center powered by Alesis Matica 500 (500 WPC, 4 ohms, bridged mono) for each of the 5 channels.
For the low end, I run 2-2X15" Tumults, sealed, EQ'd, each driver powered by a 1400W bridged QSC RMX 1450 (4 amps total), 2 dedicated 20 amp circuits, each with a Tripp Lite LCR 2400 line conditioner.
I run 1 sub as a dedicated LFE sub and the other as a dedicated redirected bass sub and sometimes, for sheer fun, I run them with a summed signal.
I'm patiently awaiting a Blu Ray victory dance to update my entire theater which will include a 990 to replace the 950.
