Hi Ed

In actuality my configuration is one step further from traditional

Since I have not yet actually taken the step of converting the EQ to a standalone op-amp circuit. My EQ is in fact a purely RC circuit that filters the response coming from a first amplifer (a NAD acting as a big gain stage). I follow this with a Hafler DH500 after the appropriate attenuation. If you think of each amplifier as nothing more than a big op-amp (thats what they are), it makes sense. The DH500 does indeed drive a conventional crossover (one 12", 4" mids and 3/4" tweeters). I also have an 18" sub that extends the low end into the mid teens.

Best regards,
Keith Larson
