When I read the INDEPENDENT speaker review by Julian Hirsch & Stereo Review that the BP10s could do 20Hz-20kHz +/-5dB @ 90dB w/m, I knew I just had to own a pair, especially at such a great price.
If Def Tech had said that these babies could go to 20Hz @ -5dB, would anybody believe them? Nope!
Yeah, by the way, I just ordered a pair of these BP10Bs brand new from my DT dealer for $700.

I am truly insane! That's all I can say.

Just for curiosity, I will hook them up as Full Range Front L + R to see how they sound. After hours of butt-kicking workout, I will then let them rest as Side Surround speakers, which is seriously overkill and crazy.
We all know the most important speakers are the Main Front Left and Right. Next is the Center speaker. Then the Surround speakers. But which Surround speakers are more important? Side Surround or Rear Surround?
