Capaciter replacement question

[HatchetJack]

Working on an old budget pair of Pioneer speakers. One tweeter does
not work so I open it up and one of the capaciters has fell apart. Gonna
replace it so I might as well replace them all right. It has two on each
crossover, a 2.7uf 100v and a 3.3uf 100v both non polarized. They have a
direct match at P.E. but I also noticed they have polypropylene capaciters
same value but 250v. Any advantage to upgrading here or is that possible?
The non polarized are .35 and .42 each and the poly's are about 1.70 or so
each. These are big old 12" woofers cs B9000 I think.

The polypropylene will sound better and last longer.

So long as the replacements are rated for a higher voltage than the originals, your fine. The non-polar electrolytics will get you back as close to original as possible. Whether you'll realize much sonic gain (or loss) using the higher priced caps is hard to predict.
