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.

Hi Bryon,

thanks for your help. In the meanwhile I could get in contact with someone of the Focal service. He told me, that the mid drives of the S and BE are the same but the casing box construction and the crossover board differs. The S is softer tuned. The S doesn't have the beryllium tweeter.

I hate to break the news to you BUT the best crossovers is NO crossovers AT ALL ! Crossovers just degrade the sound !

Hi Hifisoundguy,
Go ahead and get some Focal 1027's, remove the crossovers and let me know how it goes.

Hifisoundguy... By that you mean a single "full range" driver.

Sorry to rain on your parade, but full range drivers have a mechanical crossover due to cone breakup. The dust cap and innermost portion of the cone are the tweeter. Such a mechanical filter is difficult to design, hard to manufacture consistently, and prone to wear-out change.
