Recapping your X over?

Recommended Posts

So I have read a bunch on this and other forums and I am sure this has been covered before but I would like to hear from people who have recapped their crossovers. What do you hear? Are the improvements drastic what is your before and after story..

People who don't do it say there is no difference. People who do are glad they did it.

 

What speakers? The older they are, the worse they need it.

 

Depending on the quality of the caps used, some newer ones benefit quite a bit too.

 

Is it drastic? It depends on the crossover, what is done to it, and how you like to listen. People who just like to crank it while doing work around the house are probably wasting their money.

This is the main thing that will determine how much difference you will hear, is how bad was the original is that makes a big difference.

 

I had AA's that were leaking but working, just new caps and the same design and the difference was drastic, and they were playing fine. This was just back to stock and the difference was big, probably would have not heard such a difference if the old caps were fine.

 

As far as other designs that you can switch to, I have no idea about that, I don't know the differences, but Deang and others do.

 

Just wanted to say in some cases just new caps can make a big difference for worn out caps, so other changes could also make differences depending on what you're trying to do.

 

 You asked what differences, to me everything was cleaner and much more defined and more detail. So I guess it was more of what I was not hearing which made it sound better. I put them back together not expecting much but was really surprised when I first tried them, much better than I was expecting. Before I never really commented on people asking about old caps but now I know in some cases it can be a really big difference so I have to say something.

Thanks for the reply's I have Old Hersey's from the seventies and love them but I am curious. I was thinking of doing one reversible of course and listening and then checking out the old one that's not modified and seeing where I stand. I have a mono rig and love mono lp's so i can do this..

I recapped a pair of 1980 E crossovers and replaced the inductors, otherwise stock Heresy. I’d say it was worth every penny for more separation and clarity. I’ve also replaced 1984 Heresy x-over with a commercial set and also updated those crossovers with better caps resulting in better clarity and separation, but way more cost. Definitely worth doing, just figure out a budget.

The best way that I can describe the update is the original will sound like there was a blanket over the speakers that is removed. How bad your old caps are will determine how thick the blanket was.

That's fairly accurate as to what I've experienced as well.

Would measuring the old  caps before removal make sense? Could that be done with a regular multi meter?

Depends on the meter.  If it measures uF that's only part of what you'd need to know, though if that value is now wrong it's enough to fail the cap.  But that value could measure good with the cap still needing replaced.  The only all-in-one meters I've seen that can do the whole job are dedicated to capacitors.

 The cap can be measured while in line with the circuit and the amp connected playing music correct?

They could be measured, but if they're 20+ years old I would replace the caps if nothing else, they would be good for another 20+.
