Speaker crossover mod. Your advice?

I'm considering modding the crossovers of my Focal 1027s. Specifically, I am thinking about replacing the capacitor associated with the tweeter. I have received some helpful advice from another A'gon member who has done a similar mod to his crossovers (on a different model speaker from the same manufacturer).

I would greatly appreciate any suggestions from folks who have experience with this sort of thing. In particular, what sort of improvements can be achieved with this kind of mod? Any thoughts on which caps to use? Any common mistakes I should avoid? Is the whole thing a bad idea?

Thanks for your input.

I believe custom MR's will have to be purchased in bulk, 10 or more. On the other hand, I don't believe Duelund requires a minimum.

Having tried bypasses and mixing values of caps(MR's, Duelund, Mundorf, etc...) to attain a specific value, I would not recommend it for the HF pass. Either use the correct value(within tolerance) or split the value in half as advised earlier.

Best of luck with your upgrade, sounds like a fun project!

Jeffreybehr, have you tried Clarity's MR caps? The rest of Clarity's lines are mediocre in comparison. And as much as I like Sonic Caps, there is absolutely no comparison between Sonic Cap Gen I's and MR's.

Bryon, floating caps is fine as long as the leads are protected with shrink wrap, etc... The leads on MR's are generally pretty long.

Bryon, why split a mediocre cap and high end cap instead of just using a single high end cap? The combination of bypasses mentioned above can add artificial artifacts and can also sound very detailed, not something I would want with a metal dome tweeter. Besides, a single cap in series will have better spacial information than unequal split values or bypasses. YMMV.
