Klipsch Cornwall IV

@larbredor , 

Sorry for the slow response.  I don't get updates properly on forum threads anymore.  

If you want to upgrade the crossovers on the Cornwall IV, here's your parts list: 

All of the below *2 (2 speakers): 

2.7uF

2.2uF

6.8uF

1.5uF

4uF

8ohm/8R resistor (to replace that sand cast guy)

I used VCap ODAM caps and Path Audio resistors. Don Sachs and I both used the same parts I think and we both landed on 10w Path Audio resistors. 

I also changed the binding posts on the rear as I found the previous ones fickle. 

Let me know if you have questions, etc. 

PS @larbredor , I didn't swap out that massive 60uF poly cap linked to the woofer.  That would be (a) insanely pricey; and (b) very tricky to enigineer for me. I would have to fasten it off the PCB as it would be too big. 

Don Sachs was of the opinion that this cap would make less difference. I'd agree but qualified on the fact that I'm not an engineer.  I was also more after cleaning up the mids and highs on this loudspeaker.

I have been tempted to figure out the values of the inductors and swap those out for better quality too. However, I keep thinking that the speakers were voiced with those inductors and I don't have the know how or patience to learn how to measure and deal with what inductors do in crossover networks.  I understand it theoretically and that's all. 

Best of luck. I've never questioned my modification to this loudspeaker. I would do it again in a heartbeat. 

Anyone using the Cornwall IV's as true LCR home theater speakers? Behind screen or in front. Interested in determining if these would be a good alternative to some other floor standing loudspeakers for home theater. 

They would be kick ass for LRC HT

Any speaker brand made, relative of selling price, can be modified and improved ( in most cases ) with better parts, specifically in the cross over.
