Hi Guys. Well I finally got my HT hooked up , calibrated and etc. And I am finding that while it sounds ok in some respects I am getting a lot distortion from movie soundtracks-particularly on scenes with explosions etc. I put in U-571 expecting to be rocked and came away so disappointed.
The explosions sound like papery thin noise in my speakers. I have Polk LSI speakers all around and the surrounds are less than a month old. (LSI FX and LCI In ceiling- have to update sig.)

I don't know what I am doing wrong. My gear is certainly pretty decent. Everything is calibrated and I have situated each speaker to where it sounds the best in the room. Is the distortion more a problem with the speakers or electronics?This is driving me nuts. TIA
