However, I need a means to send only the bass to the amp that powers the

the power amps, after the preamp?

Sure. http://www.marchandelec.com/xovers.html for one.

I use an XM9 in my own speaker system. Each side has a
midrange/tweeter/midrange array with a passive crossover, powered by
one amplifier, and a side-mounted subwoofer powered by a second
amplifier. The XM9 divides the signal, after the preamp and before
the amplifiers, crossing over at 200 Hz.

20+ years since I build it, and I'm still thoroughly satisfied with
the results.

Yep, this looks just what I want. I've seen these but never knew what
they were for....


Thanks
