calibration results with spl

[COASTCUT]

Hi,
I purchased an spl meter after reading Big Daddy's calibration sticky. i put it on a chair at the listening position and calibrated all the speakers at 80db.i watched a 7.1ma movie and it seemed that the front tower speakers were overpowering all the rear speakers. i could not really hear the surround effects because it was like all the sound was coming from the front.
