Well, I think Ive gone and abused my speakers and blown the tweeters. I usually never turn up beyond reference level, but did while hosting a party. I think the source, an iPhone, had more to do with it than anything. My question, is how should I go about troubleshooting the speaker to determine if I blew the tweets, damaged the mids or woofers, or if I damaged the crossovers or any other part of the speaker. Also, can anyone provide a link to a reputable buyer for new tweets? Thanks.
