I set this up as they recommended and with a good movie it will shake the floor like what you get at the movies, I HIGHLY recommend this speaker to anyone!!

In the small room where it is placed, it shakes the walls and floor with infrasound if the amp volume is increased to just under uncomfortably loud.

I have mine hooked up thru a Sanyo 42" flat screen and at regular listening volumes, as watching a movie for example, the base almost vibrates the floor without disrupting any voice sounds

This does a phenomenal job in a 12 x 13 room with hard wood floors and a 10 ft ceiling

, it shakes the floor, and so on
