Hi Wayne,

I'm about 3/4 way done building an active crossover for bi-amping
the 3677's I got from JBL. What I began thinking about is the HF
comp network. Since it ends up being a bypassed voltage divider,
I was trying to figure out what resistor values to use for a given
compensation. If I need ~10dB of relative boost at 20KHz, starting
above say 12KHz, it seems I'd need a divider with 10dB attenuation,
then bypassed for a 3dB point around where I want the boost to
kick in. Two questions. Using 10K ohms as the series resistor,
what value goes to ground? If I'm feeding the output to the high
pass filter, does it need another op-amp buffer between the HF comp
and the HP filter?
Thx, Chris
