Jsman, in specific those speakers will probably have little to any positive reaction to bi-amping,, definatley save the money on buying a processor and additional amps and put it all into a better standalone 2 channel killer amp. You want more power or bass, go with a newer mcintosh solid state and it will nearly sound like tubes, but with rediculous power for the bottom end on that 15" woofer.. I use to own these combinations ...
