I bi-amp the low frequencies with a pair of Rowland 201s and a Model 10 on top. I use a Rane equalizer as an external cross-over to shape the sound to the room. The bass is rich and deep and does not suffer from any of the anomolies of digital amps used in other applications. I firmly believe that this combination out performs any conventional amp in the same price range.
Bi-amping LF with high-powered pro amplifiers
Has anyone tried bi-amping the low-frequecy portion of their speakers with high powered pro-amplifiers? I am think that one may be able to get the best bass definition using pro-amp such as the Crown macro tech series with >1000W/8 ohm with >5000 damping factor (rated all the way down to 1 ohm). I know most will argue that these may not be sonically equivalent to class A or A/B amps, but what would the result be if one were to direct the power from a Crown Macro tech amp to LF portion of the speaker, and use the likes of Ayre for the mids and highs?
