Best Capacitors for Crossovers

Side question: what do you guys recommend for a tweeter protection cap in an active system? Protection for DC on amp turn on, or eventual active crossover malfunction.

A good rule of thumb in an active system is the protection should be set two octaves below the tweeter crossover point. For my case, xo is 2000Hz so I'm looking at 500Hz. The calculations show the ideal cap for my tweeter and for 500Hz would be 65uF, which is large and expensive. Several of the top lines mentioned here don't even have caps this large.

Since it was only for protection I initially thought a less expensive cap would do. But the whole signal goes through it. What do you recommend?

thanks!

Ozzy,

I am using an active xo, and while I hesitated for a long while because of the digital processing involved, which rang so much as heressy within my preconceived notions, I am not going back. I'm still learning and perfecting the implementation - still haven't time-aligned my 4-way - yet it still sounds so much better. And in my case the setup is cheaper than the 2-channel I was running before.

DEQX, from what I read, is an excellent unit. If your only source is digital, then there are cheaper options that are more involved but also more flexible.
