lol it is an effort to buy 2 caps. Id just post you some, except that i dont have any 1.5uF. I got loads of polyester orange epoxy type, which i find are fine. 1uF, 2.2uF I have shedloads, but not 1.5uF.

Right, but for a tweeter capacitor, there's no way you'd even get close to the voltage limits of a poly capacitor. It's probably safe to ignore the voltage specification, or even price caps using it, I.E lower voltage caps are usually cheaper.

Your tweeters in this speaker would be lucky (or unlucky) to see 2 volts.

Ahhh I see lol makes you wonder why they bother with that big voltage, Mind u looking at it I am not sure but I thought that the cap goes to the second speaker next to the tiny tweeter as well.

well the speakers look like maybe 2ways plus sub, so i guess the other end of the cap could go directly to the positive if the midrange is run without a cross over.
