I remain hopeful to hear a great sub sat system - interestingly I have been more favorable to subs when they've been in systems with full range loudspeakers - perhaps because the crossover is set much lower and the sub is used for feeling ambiance. Perhaps I just need it crossed at say 40hz than 80hz - but that requires a speaker to be very solid at 40hz at level.
I have had two music systems that integrated subwoofer quite well. First my Magneplanar MMG + PSB Subsonic 6; in this case the both high and low pass were set at 80 Hz. Second is my MG 1.6QR + PSB Subsonic 5 where the Maggies run full range and the sub's low pass is at 50 Hz.

In the first instance perhaps placement of the sub was favourable, i.e. it was placed between the main speakers, (not is some odd corner), so there some phase problems were probably avoided. Arguably in the second instance all the really music is carried by the main stereo speakers since they are good down to 40-45 Hz where virtually all fundamentals occur, (pipe organ excepted)>
