I work at The Good Guys and we have some pretty impressive subs there. This doesn't even compaire to our heavy hitters. I have the pre-amp set at 1/2 volume and the Yamaha set at about 1/2 volume as well. I playied the opening scene in Toy story 2 where your in outer space. When the camera (animation, whatever you call it) went through the title, my system made so much bass that it woke my neice up on the other side of the house. Our house is about 100 feet long, so I was pretty impressed!
Unfortunetly I'm out of a Sub for my car! but that should soon be fixed because my good friend's girlfriend just got a new car and doesn't want to put her subs in it, so he has an extra set that he is willing to let me "borrow" them.
The only weekness in my Home Theater now it my power center. When playing U-571, chapter 15, the Depth-charged scene, you can actually see the TV screen flicker from the surge in it's power line!
