How do Def Tech BP-30'S sound?

well if you ready stereo sound and vision, then your already sold. They made you interested in a crappy bipolar speaker. Bipolars by nature doesn't sound accurate. Its bloated and unreal. There are far more accurate and better sounding speakers for much less. I would consider getting a set of used Martin Logan Aerius i for $1300 on Audiogon. Martin Logans make some of the best hts out there

Depends on the price, your roo layout and where you have been as far as speakers. I owned a pair about three years ago and put BP10's in back. Bipolars need room to take advantage of the design. Ideally about 2-3 ft in back and sides. If you can pick them up for about 30-35% off list you can't beat the bottom end for the price and they will blossom. They have their qualities and their limitaions in regards to accuracy but do offer a bang for that buck if you can accomodate placement.

I had a pair of BP-30's and found them to be a decent speaker for a stereo and H/T combination system. I would go else where if it were to fit in a 2 channel stereo only system. I had them up front for a while then used them as rear channel speakers. The system I used them in was 95% H/T and music on Sunday mornings while reading the paper. The best advise is of course to give them a listen for yourself.
