Speaker crossover mod. Your advice?

One more comment though, after reading your cap values again it is the woofer values that are the really big ones. Maybe it would be okay to just replace the midrange and tweeter caps as it's the inductors that would play the more important role with the woofer. Others on this or the other thread should be able to provide you with a more solid recommendation however.

Any opinions on the Cardas caps?

Thanks, John, for your advice. I will take a look at the Mundorf thread. I don't know the first thing about caps, so hopefully that will help.

I think the plan at this point is to replace the 2 caps for the tweeter, and possibly the resistor for the tweeter. I am going to leave the inductors alone.

As far as the midrange, I may do that down the line, if I am happy with the tweeter results. But for a first step, I am going to restrict myself to the tweeter. With that in mind, I have a basic, possibly stupid, question as I look around for replacement caps:

The caps for the tweeter are labelled "3.6J" and 6.8J." Does the "J" after the number mean joule? In my preliminary search, all the caps I am seeing are rated in µF. I don't see any caps labelled with "J". Why is that?

J indicates value tolerance; I don't know what exactly 'J' means, but I"m sure someone does.

Thanks, Jeff. Just discovered this: "J" indicates a 5% tolerance, according to capacitor codes. In light of this...

Is it a safe assumption that the 3.6 and 6.8 caps are 3.6µF and 6.8µF? Are those typical values for caps associated with tweeters?

Also, finding a 3.6µF cap has been a little difficult. The caps I've found so far from various manufacturers are either 3.3µF or 3.9µF. I assume that using a different value will change the frequency of the high pass filter. Is that a bad idea? Or is the difference - .3µF - small enough to be ignored? Should I just keep searching for a 3.6µF cap?

Anyone?
