Hello Outlaws, I need your help. I am a bachelor this weekend, and--oops--I guess I got a little too exerberant (actually waaaaay tooooo exerberant) with my volume, it appears! I think I "blew" my center channel, whatever blew/blown actually means. I have NHT M6's for center, left, and right (not run full range as I have subwoofers too) run by a 990 and powered by a 7700 for center (as well as 4 surrounds and zone 2) and two 2200 monoblocks for the left and right.

In any event, I seem to have lost the high end on the center channel as it is now muffled--but the dual woofers and midrange are still moving (I couldn't tell about the tweeter). I thought it might be the tweeter, so I put on my "tool time" hat and switched out my right and center tweeters leaving the actual speakers and setup intact. Unfortunately, after I did that, BOTH the center and right channels were muffled. Therefore, I switched the tweeters back and the right channel highs reappeared, but the center channel highs were still a bust. So, it appears, more is wrong with the center speaker than just the tweeter. Is there separate "coils" or other "driver" components that I can visually check to see if they are damaged? I really am at a loss and wonder if I need to just buy one new M6, which is going to be difficult as they stopped production last year and I doubt people that have them are going to want to part with just one and not multiples!

PLEASE HELP. Also, I want to try to fix/replace before my wife gets home on Thursday, so she won't be the wiser about my volume inadequacies and desire to compensate with high volume!

On a related note, how does a 200 watt amplifier blow/damage a speaker rated at 250 watts RMS, with 400 watts peak, and 200 watts recommended? Also, what volume setting on the 990 is safe in case I want to turn it up again?

Thanks in advance!

Ed.
