Just a quick update on the situation I have been having with M80's...

I spoke with JC this morning and we tried two more things. It has been determined that my issue is most likely the crossover in one of the speakers. JC had me swtich out the woofers and the woofer from the bad speaker worked in the other one.

He is supposed to get back to me later on today.

I will also say that I watched my first movie last night on the updated system. It was a HD movie with a Dolby Digital soundtrack recorded off of ABC-HD. Surprisingly it sounded pretty darn good. Normally when I watch movies on Directv that are in HD, the sound isn't that good and I have to crank the volume up... So even with two non-working woofers in one of the front speakers, the new center and fronts did a great job. My fiance even noticed the increased sound and bass from the center..:)
