DT makes some great speakers; dont worry. AccuDefTec will be on here telling you how great they are before long
**ha**ha**
Brad (zildjian) is exactly right on!
If I were you, I would only buy the BP (bipolar) models if I had enough room.
When I first installed my BP7000SCs, I had them about 6-inches from the back wall, with the Active Sub Drivers facing the side walls. They sounded terrible! Almost as bad as they sounded at Best Buy or other HT stores (these stores don't have enough room to accomodate the BP models either).
Now the Direct-radiating models (CLRs, SM, PM, etc.) are like any other traditional speakers and don't require a lot of spaces at all.
Just make sure you can return the speakers if you don't like what you hear at home.
But like Greg & Brad say, Def Tech make some great sounding speakers. Of course, so do other companies.
And the big BP towers (7000, 7001, etc.) have fantastic subwoofers in them, and those internal subwoofers will be wonderful for MUSIC, but they will not match a separate dedicated subwoofer when it comes to MOVIES. This is due to internal volume and the physical make-up of the cabinets.
So, yeah, I highly recommend auditioning them.
