speaker capacitors-----leave alone or does it open pandora's box ?

OP:

The TruCopper are limited in values and very very expensive compared to the reds. If memory serves, they start around $20 for 0.1uF, that's pretty pricey. Building up say a 4 uF cap would run you around $120-$150 each. This is why I recommend you try them out as bypass caps to start. 

For far less, I'd recommend the Clarity CMR range, with Audyn 0.1uF bypass on values larger than 4-5 uF. 

Again, these are BIG parts. You best be prepared to wire them. :) 

It is a MUCH easier thing for a newbie to buy some bypass caps and listen. Cheaper too. 

Best,

BTW, the largest value cap is probably on the bass and a shunt. Do not replace electrolytic caps with foil unless you have measured the ESR. 

Usually best left alone in the woofer section unless you know what you are doing. 

How does one select values for a bypass capacitor ?

Good info Eric

Thnx

@peter_s 

Usually a small value from around 1 to 5%.

I've had very good luck using 0.1uF bypass caps with 10uF main. 

In the case of the Clarity caps, at low values their caps don't benefit from bypassing at all, but I've found that the larger one's do. Do not know why. 

Best,
