Tweeter not working with acoustic 405 cab

Even though "theoretically" one can create a non polar cap by running two electrolytics in series, "back to back," I find it a cheap and nasty solution. You can get hi quality film caps rated 250V - a rating which would never fail in any reasonable circumstance - from Parts Express, for coffee break money. I've found their house brand "Dayton" to be perfectly functional. Why not skip the potential hazards of using electrolytics in this application. Install reliability instead.
Disclaimer: I have no business interest in Parts Express. Just a very satisfied user of their Dayton film caps.

I’ve had very good experiences using Express Parts. I’ve gotten great deals on big L Pads, horn drivers, knockoff speakers (mostly for stereo or PA use), and usually pick up crossover caps, etc at the same time. Very fast processing and shipping too.

You can use 5.1µF or 4.7µF.

I'm with Leo on using a film cap. Here's a good example. And, as mentioned and since the caps are in series, just use one to replace both.

Edit: I was typing while you replied. The one you linked is good, too.

What Helmholtz said ^^^. Also keep in mind, these are thumb-size caps, not rinky-dink miniatures. They will need some sort of support when mounting them. A large cable clamp or a big glob of RTV,, epoxy, or similar adhesive will do.
