Crossover upgrade capacitor question

I was thinking of upgrading my capacitors on my outboard crossovers.The boards are large with a 1 ea. of 3,6, and 2 pieces of 8uF value caps.My question is the two 8uf are strapped together and look to solder in to the same trace can I use a 16uf in there place to save money?

thanks

I would also suggest bypassing the caps in the tweeter circuit, each with a smaller .1uF cap. Don't do this in the mid or woofer sections though, just the tweeter.

Enjoy,

I suggest bypass on the tweeter from practical experience. I tried them on my mid/bass crossover caps and found that there was a pronounced forwardness and over prominence on the upper midrange that threw the whole speaker out of balance.

Now, YMMV, but it makes sense to me electrically also. Bypasses enhance upper end frequencies, and so make a difference at the upper end of the frequency spectrum. For a mid/bass driver this could be over emphasizing the upper crossover point and causing anomalies there between it and the lower end of the tweeter. Bypasses on a tweeter affects just the upper end extension and air, without any other driver interaction. At least that's the theory I'm working with to explain what I encountered.

As in all things, I recommend trying it for yourself in your system, and learning from the experience.

Enjoy,
Bob
