I have searched the Forum and Interweb and cannot find what I am looking for so......

Can any of you nice folks out there help me with schematics for SP2004 and SP1052 crossovers.

I have several crossover pair and it's time they were got rid of so want to sell them with details of components.

Thanks for looking.

SP2004 was the Coda II. It was a simple crossover, 450uF series capacitor, 2nd order bass rolloff with a large inductor and 4.2uF to ground. The treble was 3rd order with two 7uF capacitors, and a small inductor to ground.

SP1052 was the Corelli and somewhat more complicated, circuit here:

Thanks for the response.

The SP1052s I have include 3x 10uF, 1x 3.3uF and 1x 30uF caps. Not quite the Xover you describe.

I am looking to give the info as inductor values might help me get rid of them. The Caps can be read easily but KEFs colour coding for coils is a different matter.
