[Crites Type AA crossover...bi-amp modification]

Has anyone modified the Crites Type AA crossover to allow bi-amping? I emailed Crites and they said they could send me the schematic, but I don't want to pester them about it. I was hoping someone on here has done it or knows enough about crossover design to draw up the schematic for me. Thanks for any help.

[La Scala vintage builds]

I'm doing it right now. I put the second round of primer on the top hats about an hour ago. A little spot putty and one more coat of primer and it's on to the bass modules. I'm also using all Crites components and original K-400 horns. But with a twist. The bottom section will be a subwoofer with 15" Stereo Integrity drivers. I'm also going to mod the crossover to allow bi-amping. These will all be separate components, so the LaScala clones can be put back in their original configuration if needed.
