Active Crossover Recommendations


I want to experiment with using an Active Crossover to seperate high frequencies (going to my Quad 988's through Cary EL34 triode amps) from low frequencies (going to self powered subs by TBI or an ACI Titan). Can anyone recommend a good active crossover with a steep slope for this application. I would like the Xover frequency to be somewhere between 80-120 hz, best case around 100 hz.

Thanks very much for your suggestions.

hi greg, so if i understand correctly, this is 6db per octave, yes?

and, if the high freqency amp had a gain of 20db, and the subwoofer amp had a gain of 10db, then "a" would be 2, and pi would be 3.1417, correct?

the cap would of course go in series w/ the high freq amp, while the low freq amp (the sub) you could simply rely on its own internal crossover to filter out higher freq info?

does anyone have the equation for calculating required capacitance for use in a crossover (given amplifier input impedance)? this thread stalled just when it got handy...
