Just picked up the pre-street from my wife's work. All I can say is WOW!!! Even on my humble system my setup has never encountered a heavy workout like this dvd. This movie totally immersed me not only with the sound but also the video. For all you bassheads out there you will be glad you bought this one. There is one scene in particular that had my sub going for 10 minutes or so.SpoilerThe scene in the club. There was lowend bass for around 10 minutes or so. I'm assuming around 20hz and less.
