4355 external crossover recommendations

[chef free]

Did JBL make an external crossover to go with the 4355? If not, any ideas? Using DBX unit now, looking at Bryston 10b...

For Bi-amping JBL had 5234A and 5235 electronic crossover. The correct cards are 290hz @ 18db

I am building the same system and found a gentle man here in Ontario that made me a charged couple crossover that I picked up today. It has controls for my mids-highs-ultra highs and then use my DBX 260 drive rack for bottom end. The workmanship is beautiful and Chris has built a few pair of JBL 43xx speakers and really knows his stuff. It came in a beautiful box the looks like a piece of furniture it was so well done. I will be biamping the system with
