Watched black hawk down for the first time with my dual 12" subs. All the way through the sound was OK...not really all that impressive. It was loud...gunfire..helicopters...sounded alright. The Irene Scene was 'meh'. A little action from the subs, but they werent really kicking in. Not much air out of the rear ports. I checked my settings all the way through the movie thinking something was up.
ANyway, at the end, I decided to poke around with the BD settings and the 'audio' button. Apparently there is a default 5.1 and the second setting is LPCM 5.1 which seems to have a LOT more data associated with it I guess. Anyway, the sound from the Irene scene THEN sounded like I thought it should. In fact, everything sounded better...a LOT better. Helicopters rumbled my walls, gun shots split my ear, it was amazing. So what in the world is it and why does it sound so much more awesome when the default DD 5.1 is so blah?
