I agree with you randy.... No question - external subs even though I wasted my money on those Sig S8 towers, the XLERATORS are far more capable then the bass in any main - same goes with my choice for buying these SS M7's.
Well guys I spent a really good amount of time after getting them set up last night - in a word INCREDIBLE.... Jim and Dennis you guys worked magic and they are certainly worthy of the SoundScape label...
Oh and BTW, they can crank pretty darn well despite the efficiency rating, more then I will need in a room that size... As far as comparing to the Sig S8's, its too early, seriously I just got these last night... Both are great speakers, but SQ wise - IMO these will beat out the Sigs. But in terms of output wise for my HUGE HT room, these just couldn't push the SPL's like the Sigs can - and the S8's sound awesome doing it....
Cheers
