rewire older speaker internal wiring?

Any good wire should be ok.Good tight connections are important.Also,don't use higher uf,or mfd values on the caps
unless a real pro tells you its ok.That will pass lower frequency's to the drivers possibly blowing them.A little higher voltages should be ok.There's a lot of JBL fans on the net that may have places for help.

Many people experienced in this rebuild will tell you to use a parallel 'bypass' cap of some small value.
Don't forget that caps in Paralled ADD values.

Solon is a good choice as is Clarity SA for more $$. It gets wacky after that and in my OPINION should not be purchased unheard or without a knowing recommendation.

My panels start wit Solon and I am pricing out a new x-over of identical design to original, using Clarity SA. I could spend more $$ on a single Mundorf Gold/Silver/Oil (whatever) than I intend for the entire project!

First rewire the innards...and then I will advise you on the crossovers. If you want my HO that is.

Thank you all for your input.
Vandermeulen, I will contact you once I have replaced internal wiring for advise with the caps.
