The audio was awesome though. I never gush over the latest action flick soundtrack. In fact, when asked for demo discs, I rarely reply cuz I only have a small handful that are truly reference in my opinion. Others seem to list off every action movie ever released.
I prefer THX ULTRA2 + DD5.1. Using bipoles surrounds in 7.1 config. Symmetrical speaker placement in rectangular dedicated HT. Sub calibrated with Velodyne SMS-1.
POTC2 is a reference disc for me. Truly seamless, enveloping, engaging, believable. Other mixes are front heavy, others have gimmicky surround action, others have overcooked bass (Tokyo Drift, The Island, Haunting DTS). Dialogue was clear and during the 2.5h runtime, I never thought it sounded like ADR.
Bass is deep and visceral, but never overdone, as if it's trying to impress you. The bass from Davy Jones' heartbeats doesn't blast you or flap your proverbial pant leg, but rumbles at a more visceral and natural level that works to increase tension. The score when going full tilt didn't sound congested or bright. It was easy to keep turning the volume up because it was never glaring or harsh. My room does have the side walls treated though, as well as bass traps in all four corners. Surround action is superb. I know 4 bipoles and THX ULTRA2 go a long way in dispersing the rear soundstage compared to 2 monopoles, but I got completely lost in this mix. I love it! It fully deserves a place beside my #1 reference disc: Master and Commander (DTS).
