Decent cheap caps for fixing / flipping speakers?

An aquaintance has a small stash of diassembled vintage monitor polks (no peerless) RTA 11 & 8 and some other speakers that are in rough shape. They might get sold as parts, but I was asked if I could maybe get some working again as a friendly favor. They may keep some for there kids too. They are interested in audio, but not really audiophiles.

All the speakers and tweeters appear to work. Some crossovers are missing caps and resistors. The cabinets are ok to rough but not damaged.

They are not worth clarity or sonicap if no one notices, and probably not worth dayton either. I'd rather not go with electrolytics, but that is what was original. IMO a cheap poly should sound better and at least last for its remaining life. Any suggestions?

    Dayton 5% or Bennic. They're pretty much the least expensive Metalized Polypropylenes out there, that don't burn your ear drums.

    Yup.
    A little 'bright' sounding but very good value and an improvement for any vintage monkey coffin, IME/IMO.

    TY. As far as burning ear drums, are these MP's better sounding than Electrolytics that would come stock?

    Virtually any moder non-electrolytic capacitor (film and foil, polypro, oil, etc. etc.) will sound better (smooooooother) than a nonpolarized electrolytic in a high-pass filter (at the least), IME/IMO (and FWIW, YMMV, etc.) :)

    These are nice -- li'l pricey though B)

    That being said, modern, fresh NP electrolytics (which are dirt cheap) will also almost certainly sound better than four decade-old NP electrolytics in a vintage "monkey coffin" Advent, EPI or whatever loudspeaker. :)
