also MF like how they have it is the OLD way of saying MICRO farad. today's standards use µ

I do know the MF and UF are more less less the same. And thanks for the links. Seems to be everything decent I can find in the right size and rating seems to be too small. Oddly smaller caps don't play well with the set. I tried a few 47uf 16v caps and the smaller the cap the more they disport the sound.

are you using non polarized? I think that matters quite a bit.

The crossover components appear to be in series, so the capacitor will be acting as a high pass component. The critical frequency will be omega=1/(RC) or f=1/(2*pi*RC). Therefore lower frequencies will be passed to the coaxial tweeter when higher capacitance components are used. Also, higher ESR will decrease attenuation and pass lower frequencies to the tweeter.

Yes, this should be a non polarized capacitor, as the circuit is unbiased.

I'm using bi polar, its what I had sitting around.
after messing around with a few different caps I found that a 4.7uf cap gives the cleanest sound, less bass but cleaner sound none the less.
Higher capacitance tend to just distort the sound. more so on the right speaker.

Yes your right on with how the cross over works

If you can get non-electrolytic in the size, that may give better results than bipolar electrolytic

Yeah I was thinking of getting film caps.
