Dayton DMPC-6.8 6.8uF 250V Polypropylene Capacitor

These capacitors are a great replacement for capacitors in old speakers. They will make them sound much better. They aren't exactly cheap for capacitors but that's OK.

I always turn to these capacitors. For the price, they deliver good performance in limiting the low frequency sound. The resulting higher frequencies come through clear and pure. When used together with an inductor, these offer a reliable way to tune your system.

I had to replace a cap on my B&W speakers crossover so I figured why not spend a little (and I do mean a little) bit more for some poly caps. I figured that these would be more durable than the electrolytic bi-polars that where in there. Well, I gave the speakers a listen with the old caps on a really nice Count Basie (sp?) CD (I had replaced the blown cap with a stray electrolytic bi-polar). This helped me determine that the left and right sounded similiar. Then I updated one speaker and listened to them side by side. What a difference! The old speaker sounded like it had a mud filter on it while the newly upgraded one sounded much clearer in the higher frequencies!
A worthy upgrade.
Now I'm running around the house to see what other speakers I can upgrade.
I've always enjoyed mid-high end (not esoteric$$) gear but have been skeptical about things like cables and caps. I'm convinced about caps; cables not so much so.
