Mundorf Supreme EVO Oil Caps

Oil caps; hype or valid benefits (for a tweeter)?

I’m running my beyma 5 in coaxial, with no low-pass on the midrange and a 2nd order LR high-pass on the compression tweeter with Clarity Cap CSAs. I’ve been a fan of the CSAs (some here have differing views -ok) and I’m good with my current filter, but I’m debating trying a 1st order high-pass (apparently better phase integration in this set-up with no low-pass on midrange) maybe trying EVO Oil Caps? The beyma is a pro-driver with good power ratings and I’m running it with a low-power ACAmp.

I’ve been looking at the Totem Tribe Tower Thunderbird running two 6 in drivers full-range / no filter with a 1st order low pass on the tweeter- very interesting (keeping it as simple as possible, but not simpler). Anyway, the phase relationship of a 1st order would be better than a 2nd order on the tweeter in this setup. And if going with a simple 1st order (+Lpad circuit) for this coaxial compression tweeter, thinking oil ?

Any and all comments welcome- especially for oil can fans - thx

If going to try oils, try the ASC X386, X387, or X389 models. I’ve not really had favorable/preferable results with the white Mundorf caps, oil or not.

Thx for the suggestions.

I want to try a 1st order high pass on a tweeter with a non-filtered mid or woofer build (possibly with a .5 woofer?) but thinking a $300 coaxial is not the place to get my feet wet (smoke a tweeter). Could be an interesting project - and with just a single cap (ok a resistor or two) on the tweeter maybe some oil / foil / wax for the tweeter cap…

I tried the Mundorf oils and didn’t like them too much either.

Bevenbi makes an aluminum/oil and a copper/oil and they tend to be cheaper than other brands.

what were the objections to the Mundorf oily caps?

It could be I’ve not found the right tweeter match for it, but I’ve heard other people’s builds with them too that I felt left some expected performance on the table. I would characterize their imparted sound qualities as bland, rather closed in in terms of space, and murky.
