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

I'd give up on the BSC, and focus on measuring your own setup.

Every room is different, and the miniDSP will give you all the flexibility you need to integrate the sub to the room and your other speakers.

Let it do everything.

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.
