I was gone for a few years and came back today to talk caps and I see your interest in the topic.
After re-watching Steve Eberbach's youtube video from SMWTMS, he warns about being time to replace the electrolytic caps, particularity on the tweeter to protect it from "leakage" and non-linear effects. So, I'm just doing the electrolytics. Let us know what you think.
I'm not as WOWed by them as I once was. They seem to be working properly, but have lost much of the open and detailed soundfield that I loved. I have gone through some equipment changes, mainly preamps, and had to get my power amp repaired, so that may be part of the problem. I have found that Audyssey tends to suck the life out of music, so I thinking of buying a older two-channel preamp solely for music. I'm thinking something like an Acdom or Proceed.
However after sending off my amp for repair, which was for failed capacitors, I started thinking about replacing them in my crossovers.
I saw a video with Steve, might be the same one you watched, where he mentions replacing the electrolytic capacitors. I also talked with the guy who's doing my amp repair. He suggested replacing them with a Panasonic Long Life High Temp versions - Series FR for the larger ones, and series EB for the smaller ones, or the Erse would be a great option. He says the Mylar film caps are most likely fine, unless they are discolored.
I'm going to pull a crossover and see about ordering replacements for the electrolytic caps, for sure.
I have the itch for new speakers, but thought I would try recapping first. Thanks for the reply.
