DIY Klipsch Crites-style Crossovers

[Netdewt]

Has anybody done their own crossovers?

I just acquired some KG4s and I'm wondering about redoing the crossovers, but the Crites one is over $200. I paid $180 for the speakers. Looks pretty simple, but I'd need more help than this picture:

Building them is the easy part, the designing is where the fun happens

What kind of help do you need?

I'm just learning how to read schematics, and I'm doing this completely as a hobby. My work has nothing to do with audio or electronics. I just saw the picture of the Crites crossover and thought it would be easy to build and not involve lethal voltages, if anyone out there has a schematic. Just looking to get some feedback (in this thread, not in the speakers).

No schematics out there?

Have you checked out the Klipsch forums and Audiokarma.org?

The schematics are on the Klipsch forums (do a search). Bob's rebuilds do NOT change the design and crossover settings. Any inductors or autoformers can be reused, along with the barrier strip.

My suggestion is to simply replace the caps with reasonably priced parts from Parts Express (eg. Solen or Dayton). If you want to get fancy, then bypass the caps (eg. parallel a second film/foil Dayton cap with about 1-10% the value of the main cap).

Unless you have measuring equipment and are comfortable with some basic theory, I would NOT recommend a redesign of the crossover circuit.

I realize that it wouldn't be exactly his schematic. Just wondering if anyone has any other sources for a passive crossover like this. It looks so simple. I'm not trying to be annoying. There seem to be lots of other DIY projects out there.

diy crossover for crites cs 1.5 speakers

are there any plans out there ?

Don't bother paying Bob Crites for a few caps and solder. Just wank the cross overs out and replace the capacitors, like what WithTarragon suggested. A buddy paid Crites to get his done, he got ripped off. I tried to convince him to do it himself. But he was afraid I suppose.

I imagine you would only buy the crossovers if you had none. If you already have the speakers complete upgrade the caps.

Klipsch factory employees' wives used to assemble those crossover boards at home to make some extra household income.

They typically used the old screw-down oil-filled capacitors, do those degrade with time?

Bob Crites uses Dayton electrolytic for the bass roll off cap and Sonicaps for the rest. I did my Heresy's II which has all the passives on the back cup so it was a little bit more challenging than what you got. I also did a friends Cornwalls that came out real nice.
