Hey, sorry for the lack of an intro, but I have a technical question that I would like answered. I have a set of rt-8 speakers, with sl5001 tweeters in them. I got them from my brother, and one of the tweeters is not working, but its getting power to it. I tried swapping the tweeters between the two speakers, and the other one worked fine in the case. I am just not sure what would cause this tweeter to not work? Am I out of luck, and have to purchase a new one? or is there something I should check for? Thanks.
