    Has anyone modded 25s or FXs yet? I want to modify my system all around. The C will be easy, I'm just concerned about the others. I haven't seen anyone try those yet.

    Nothing was modded, per se, on the 15's or 9's--Just replacements (upgrades) of existing components with like values. No reason you shouldn't be able to do the same to any speaker XO, IMHO.

    Well to clarify, it might be considered a 'mod' by replacing the electrolytic caps with film caps, but still the same applies.

    I've heard of one pair of 25's being modified, but haven't heard of FX's being done yet.

    As long as you keep it simple(tweeter caps, resistors), the C isn't too bad.

    As for the 25's, do not remove the large value cap in series with the mids. Either parallel a few large value caps or bypass the stock electrolytic with a 5uf film cap. If there isn't enough space, you can go with a smaller bypass cap.

    Well I suppose I didnt mean modify but rather "upgrade".

    Instead of paralleling caps, wouldn't it be better to just have a custom capacitor made? I would rather save space and have it look cleaner. I really wanna talk to one of you guys in depth over the phone or on an instant messenger of some sort and learn more about this stuff. These upgrades will be my Christmas present to myself, so I want to learn as much as I can before then

    I'm not aware of any 500uf film caps and a custom pair would be ridiculously expensive, if available at all.

    When paralleling film caps, especially caps in series with a tweeter or mid, all caps should be the same value(divided equally). Three Solen 160uf 400vdc caps in parallel would be the closest to 500uf that I'm aware of. Dayton and Mundorf also make a few large value caps, but nothing that would be practical for your application.
