Well, This thread died but st the end I bought new crossovers from Crites, but I was never really happy with my pair of LaScala. I sold them a few months ago and got a fairly good price so I was happy.
But my search continued and I was looking for horn speakers and it had to ble Klipsch, so suddenly I talked to a gut who had a big warehouse and he told me that he had several klipsch systems after a cinema thats been closed. So I got a pair of 535 from him. They sre in s really nice condition and sounds awesome!!!
I wanted it simple so I ordered a three way passive crossover from klipsch instead of using a active crossover.
And I really really love them!!!
