Dayton DMPC-25 25uF 250V Polypropylene Capacitor

My tweeters are actively crossed over, but I still needed a capacitor in series below the active xover frequency just for safety (if there is ever a turn on/off pop or other noise, I don't want a blown tweeter).

These caps work perfectly and didn't degrade the sound at all, but holy cow batman...they are the size of the tweeters themselves!

The difference is staggering. You wont believe it till you try it yourself. Finalize you X-over with the cheap stuff then get these to replace your finale design values. Your project will be so much more impressive.

I had thought for the longest time that a capacitor was a capacitor and the differences that (audiophiles) hear was imagined, but its not. I havent tried the real high end caps yet but there is quite an audible difference from an electrolytic capacitor and these.
