Any suggestion of capacitors that using in a clone R3.8 X-over??
I've already order some Clarity Cap SA, is it good to use in R3.8??

Thanks!

I've no experience of them in your specific x-over design, but I have used clarity cap SA grade as replacements in the x-overs of my old JBL Rhodes C-37 and they sound just fine.

What's an R3.8 and what tweeter did you use?
I'm using Clarity caps with a bank of Jantzen caps as the base caps in my crossovers and I also parallel a bank of film&foil caps across the base caps. The F&F caps are a combination of .47, or .33, .22, .10 & the .01's to make up the final 1 uf.
It's the bank of F&F caps that I heard a difference in the sound. The soundstage became cleaner & clearer.
The base caps cost no more than the Solen's and it's these caps that I replace that makes the most difference.

WoW! Them drivers probably deserve nice crossover components.
Here's more info on bypassing caps that I came across after I stumbled across an audible difference in caps.

Thanks a lot!
Since I order Duelund Graphite Resistors & Clarity Cap SA, also ERO MKP1837, according to Tony Gee's suggestion, I think the result is positive!

Beside, how about Jentzen Cross Cap??
