Anyone has a crossover schematic for 804S?

[Horacio]

I'm looking for the crossover schematics. Anyone has them? 804, 803 would be fine. 802 might work too.

I know I can just open my speakers and draw them, but I'm trying to avoid opening them just for this. yeap, could also say I'm lazy! :T

Thanks!

It should be in the service manual, downloadable from here:

Thank you Shadow! I wasn't aware this document was readily available. Great!

I'm not fully understanding the schematics, though. When one uses just one pair of wires to drive the whole speaker, hence connecting the two positive and two negative binding posts in the back, there has to be an internal crossover to divide the LF from the MF & HF...but which part is that?

Thanks again!

From the schematics, there's three crossover's in there. LF binding post goes to the LF crossover which has two outputs for both LF drivers. HF binding post goes to the MF crossover, which has an output going to the midrange, and an output that goes to the HF crossover. HF crossover has an input from the MF crossover and an output to the tweeter.

The 804s has dual binding posts.... Even when connected together the top binding posts got the HF and MF crossover and the lower posts go to the LF crossover..

Thanks for the answers.

So when the two pairs of binding posts are NOT connected together in the back there is nothing really being bypassed, ah? The low pass filter is still there. For whatever reason I thought it would be different. I guess these are bad news for my active crossover + biamping plans...

Oh well. Better be aware ahead of taking the plunge.

Thanks all!
