Dayton DMPC-20 20uF 250V Polypropylene Capacitor

I designed five of these (different values) into each of my new crossovers. They are superior to NP electrolytics in accuracy, stability, and distortion. They are priced right, and are reasonably compact. They did everything I expected.

I used these caps with my woofers, to go with the coils in a second-order low-pass crossover. I was pleased with the result (a much more definitive bass) but I was also pleased with the price. At just under $6/cap, this product is 7 times more expensive than its electrolytics equivalent, but what's $7 - especially when there is no equivalence between electrolytics and polypropylene? Furthermore, Dayton's caps are a mere fraction of the cost of buying Danish. This isn't even Dayton's top cap. It's just that, on low-pass crossovers, the cap is not critical, so you can make an excellent upgrade that won't break the bank. This is one of those times where buying American makes good sense.

Worked great to recap my 30 yr old RS Mach one speakers. Sound great now. Bass response is tight Midrange and tweeters are clear. Nice increase in spacial aspects of the sound.
