Which cap would help reduce sibilance?

[andy2]

I recently build a parallel xover version for the Eros speaker but the speaker still have a bit of sibilance that I want to reduce. My xover currently uses Solen but I am looking for something that will reduce sibilance a bit.

Do you think it will be worth it to upgrade the tweeter xover with all Mundorf caps?

Use SCR tinfoil as the cheapest cap with sweet sonics. Try to evaluate if you miss a little midrange. Missing midrange always tones up treble, and sibilance is tell tale when it is happening.

Do an impedance test on the system, if there is a peak in the mid range section, try getting rid of it first.

Have you tried adding small bypass caps to the main caps? It may help.

I added 22nf (10nf is recommended with some caps) polys to my crossover caps (SCR and MCAPs) and it made a marked improvement - the sound is smoother and more refined without loss of detail.

Try checking your actual frequency response first. You'll probably find a peak in the 3-6kHz region. Tame this first by adjusting your actual xover values before you start looking for just changing the cap.
