    Hey guys, I've got a question about my vintage JVC A-GX3 stereo amplifier. I bought it about 2 years ago and it was supposed to be refurbished and cleaned.

    Help with Klipsch k77 Tweeters and Different Volumes

    So, I picked up a pair of Klipsch K77 tweeters, for a yet-to-be defined project. Price was right. Or, at least seemed so. I hooked up both tweeters to a small 15W amp, just to test 'em out. The volume from one was significantly louder than the other. The louder one seemed distorted a bit...
