I purchased a used RC3 center channel speaker for my home theater. I expected to be blown away, but the sound quality just is not great. Because this is my first klipsch speaker, and I did not have anything to compare it to, I thought that this was just the way it sounded. But after watching TV for a few hours, I began to think that there was something wrong with the speaker. The sound is harsh. S's are over pronounced almost to the point of a hiss. Maybe something got rattled loose or broken inside during shipping.
So, I did some experimenting. I removed the brackets that connect the two sets of post and hooked the speaker wire to the bottom post alone. It sounded just like before. When I hooked the wires to just the top post, there was very little sound coming out. I had to crank the amp to hear it clearly.
Does anyone have any ideas what the problem might be? Anything I can try doing? My local repair shop wants $40 dollars to do a diagnostic with a $135 authorization. I only paid $150 total for the speaker.
