Bennett Sound Corporation Compusound Circuit (integrated amp/crossover) question


Hi,

I am new to the forum but have a question that I am struggling to answer.  I have a Kinergetics SW-200 integrated power amp/crossover that incorporates a Bennett Sound Corporation (BSC) Compusound circuit in the system.  The amp is quite old, so I thought I might look at using a miniDSP to do the crossover, but I can't find any technical information on the BSC circuit. Does anyone have any specific technical information on the circuit that I might use as input into building a digital filter to emulate the BSC circuit.  The SW-200 drives a pair of SW-100 kinergetics subwoofers and I am running a pair of Martin Logan CLS's in which I recently replaced the panels.

Many Thanks, Mike

Well, that is my general plan.  I can clearly see a +6 dB boost at low frequency, which is easy to implement with the DSP.  But, apparently they are designed to work optimally with some form of feedback/forwards circuit that makes them sound better than just crossing them over and adding power (which I have also done).  I'd like to figure out what the designers were aiming for to see if I can emulate that with the miniDSP.  Right now, with the DSP they have a tendency towards one-note bass that isn't present with the electronic crossover.
