Hello, I recently bought 2 Floorstanding TSi300 speakers at best buy for my new Denon AVR-3310CI Reciever. I assume I hooked up everything properly and so I checked the Ch. levels of the speakers in the options menu. Apparantly my left TSI speaker sounds duller than the same model on the right side (Sounds from the right speaker sounds more crisp to my ears). So I switched sides to see if it was the speaker wire. Same speaker still sounded dull even on the right side now. I messed with the DB levels on that speaker to try to match the other one but it wasnt really a loudness issue more of a clarity issue. Someone told me about the metal plates behind the speaker that is connecting Red-Red and Black-Black and to make sure they are tightly secure, which they are on both speakers. Could anyone point anything on this problem? On movies and games I can't really tell the difference since its very loud no matter what but music i can hear the difference. Is the speaker busted? Thank you for your time.
