active crossover recommendation

While not listed on their home-page, the fellow at GR-Research can make a crossover for you I'm sure.

I call him "the fellow" because he never introduces himself.

The fellow is named Danny Richie, but I don't think he builds crossovers. He sells DIY speaker kits, which include the parts for making the passive crossover filters the loudspeaker uses.

Old saying #1: Money talks. 

Old saying #2: It doesn't hurt to ask.

Three-way is not easy to find. You might evaluate Marchand, as previously suggested.

This could be worth a look.
