Hey guys, I just had a question. I own a set of 5.1 Cambridge Sounworks DTT3500 Digital Speakers. Its 4 speakers, a center, and a subwoofer. It is hooked up to my pc not my tv, but I figured I could ask here anyways. How can you tell if a speaker is blown? What are the tell tale signs? I ask this because I put in a dvd, and didn't notice the reciever's sound dial was up about 3/4 of full power, and when the dvd started it was VERY loud. I am just wondering if I can tell if it busted my center speaker, and if there are places that would repair it IF its broken. If you need anymore info let me know, i would really appreciate your help everyone, Im trying to learn all I can. Thanks!
