I just received my paradigm 40 speakers in the mail today. They were packed very well. I bought them from www.tsto. Cosmetically they look brand spankin' new with not a scratch on them. But when I hooked them up I noticed that the right speaker was audibly different from the left. Not noticeable when sitting on couch but definately something doesn't seem right with I put my ear up to the speaker. The tweeter has a different sound than the left speaker. Also seems like distortion as well. Is the tweeter bad? Maybe its just a bad connection on my speaker wire? The latter which I doubt. Like I said these were bought used. Would they still be covered under Paradigm warranty? Thanks for any help and suggestions.
