hi, what difference I can find if I replace a original cap 3uf by other 2.2 or 3.3uf for tweeter driver?
in 3.3 a Bandwidth is more opened ?
 
Why not use two 1.5 Uf or three 1.0 uF in parallel? Crossover values should match exactly.Too small and you will have a mirange hole. Too large, and you have a mid hump, and may overpower the tweeter.
 
if I use this correctly, 2.2uf will have a higher frequency range: http://www.diyaudioandvideo.com/Calculator/XOver/

That is consistent with the tweaking I did on my polk sl2000 tweeters.

A 2.2 uf/250v didn't block enough of the mid-range frequencies from getting to the tweeter so the tweeter was still a little harsh. A 1.0 uf/250v did the trick in most cases by changing the crossover point a bit lower than the 2.2 uf as indicated in my signature.

Caps block the lower frequencies from getting passed on down the signal path.
 
2.2uf will leave out a lot and create a hole in FR. 3.3uf is within 10% and should be acceptable.
