TruSonic by AVMS is your best bet. of course, as the owner, im biased! BUT for $3995 including shipping you get your $6500 worth and that includes TWO 12" powered remote controlled subs. Wait for the reviews in TAC, T$S, or Bound For Sound or just call toll free 888-803-3770 30 day trial!
Speaker Suggestions
I am currently using the B&K AVR202, with a Marantz 930 DVD, Kimber 8TC cables and Wireworld Interconnects. I am using a Definitve Technology setup all the way around and looking to upgrade. I have about $6,500 to spend on all speakers including a sub. My room is 25x17 with 25 foot ceilings. Any advice?
