I'm having trouble finding replacement tweeters for my t15 bookshelfs which I have blown for the second time due to overpowering. Back in March they cost only $50.88 shipped, but now four months later they cost $67.81 which is what I paid for my m10's. I'm willing to upgrade or find any tweet with the same outside diameter (3 7/16). I work in a loud machine shop and will not turn the volume down!

    Sounds like you just need more powerful speakers....

    I think his tweeters blew due to under powering them by driving the amp to clipping. A lot of people do this and blame the speakers.

    Definitely could be that, rebuy....

    What are the power ratings of your speakers and amp, Greg?

    Thanks for the reply. My receiver is an older fisher rated at 80 wpc and 0.9% thd. Should be clean enough for a speaker rated at 100 watts max. I'm just trying to salvage what I have before I buy something better. I also burned up my Advent baby II's (6 ohm?). This is a labor of love. Rock on!

    Considering that you're using an old Fisher that is likely very overrated in power and has a high THD spec, I would suggest that rebuy is correct--your amp is clipping and destroying your tweeters. That receiver is definitely not enough to run 6 ohm Advents.

    Whatever you end up doing, you might want to consider turning the volume down until you are able to supply cleaner power. It will cost you a lot less in the long run.

    ...just my $.02

    Yep sounds like an underpowered amp.

    How far do you have the receiver turned up when listening? What are you using for a source (iPod, CD player, et c.) and at what level is that played?

    It's the Fisher doing it. It isn't strong enough or clean enough for those speakers.

    You will just continue to kill tweeters.
