I own a velodyne SPL 1200--very nice clean sound. I also have a friend with an HSU--also very nice but not quite as clean. The velodyne is also small. Retail price $1399 but you can find on the internet $850 range. You received good advice above reference HGS10 subs--I haven't personally heard them but have read alot of negatives.
I have B&W N804 and am very happy with the combination. Also have the N HTM1 for THX--I had a friend who tried to sell me a B&W ASW-3000 and the velodyne is much much better. We listen to the same music and velodyne has a nice sound along with the B&W's --- but as always trust your own hearing.
