The "Underworld" DVD can indeed be added to the growing selection of motion pictures that make good use of the LFE channel. I would guess that a lot of the sub action was stong in the 30 to 40 cycle range. Occassionaly I would hear/feel something down near the 20 to 25 cycle range.

DVD's like The Haunting, Lord of the Rings 1 and 2 and Das Boot have longer, sustained action the the 20/25 cycle range.

My two cents...Mark
