Howdy, I'm new to this scene so forgive my ignorance. I recently acquired two old Cabaret 4628 keyboard speakers, 3 way boxes that have been modified so there is no crossover. They must be triamped with these weird 8pin connectors (6 used) and I want to convert them to passive boxes so I only have to plug in one cable. The crossover points are I believe around 220 and 2.5k. They have e145 15-inch woofers, 2118H 8-in. mids, and 2404 tweets. I would be glad to part these or sell the entire boxes, but they weigh 105 lbs each and I live in the seattle area, so I won't even attempt to ship, though I will be happy to drop them at a mail box etc uncrated. All components have been tested and work, though the wiring from the input jack to the tweets seems to be loose. CAN ANYONE TELL ME WHAT CROSSOVERS i NEED AND HOW TO GET THEM?
i APPRECIATE IT! EDDIE

The crossover is rudimentary; you should be able to build it yourself.

Ignore the jack switching, and it's just two capacitors, a coil, and an L-Pad:

I can't read that, either. :p

This is better:

13.5 uF isn't a standard value, so it'll be 12 uF + 1.5 uF, for example, or three capacitors, total.... :thmbsup:

Not up to that? JBL Pro Parts lists the crossovers for $72 apiece. #63350

They'll likely come in dusty old "vintage" boxes.... ;)
