Klipsch Cornwall IV

No, I am a tube amp, preamp, and phono builder, not a speaker guy.  I have a pretty big list of things to build.  I just do those other things for myself and really don't have the time for youtube or social media.  I really wouldn't want to be responsible for someone destroying their speakers and voiding their warranty if they watched my video, but they didn't know what they were doing.   Or having to answer multiple inquiries on something that isn't even my product.   So I stay out of the limelight.....All I will say is if you know what you are doing you can improve this speaker considerably without losing any of the things you love about them.

@raindog69,  I have some photos that I could share.  I performed a similar if not identical upgrade as donsachs.  

I would say this is an intermediate level project.  I didn't find it terribly challenging on the skill level, but I did find it taxed my patience.  

There’s no question in my mind that the CW IV crossover can be easily bettered with more substantial parts. The caps and resistors are run of the mill. Careful here--I’m not saying that leads to run of the mill sound. See my post on modifying the Carver Crimson 275 amp. Bob used some decent and some dirt cheap parts in it. The coupling caps in that thing were the size of my pinky fingernail. They are inexpensive and not of good quality. Can they sound ok in a good circuit? Sure. Same thing with Klipsch CW IV.

I’m not saying folks should do this to the CW IVs. But, I will venture to say, and I’ll bet DonSachs would likely agree, many folks will question what he and I have done here while they are out buying very pricey power cords, interconnects and so on. This upgrade will best all of that in my humble opinion.

My CW IVs are about 100 hours in or so. They sound glorious. VCap ODAMs are really special caps. They almost sound like the cap is out of the system.

@jbhiller Thanks for the offer, but even with detailed photos, quite frankly, I'm unlikely to attempt these modifications. I lack two necessary things at the moment - time and patience. Maybe one day, as I'm sure the mods would make these speakers even better than stock.

As Don had indicated, you need to ensure the VCap ODAM bodies don't touch anything conductive as they are conducive too.  I started by applying high grade silicone tape (electricians use this to cover high amperage lines).  However, I got a bit nervous about anything touching so I tore it off and started over by wrapping each and every capacitor;  peace of mind.

@jbhiller , many thanks for the details on your mods. Between your experiences and Don Sachs's, I'm getting closer to trying them myself.

So what exactly did you end up wrapping the ODAMs with? And how did you glue them down?
