WSJ.com - The Mossberg Solution: A Killer Amp -- for Your Desk Chair "Is this a great country, or what? Thanks to technology, you soon will be able to not only hear your favorite music and the sound effects of videogames, but to actually feel these sounds, and not just in your heart and soul.
An outfit called Guitammer Co., from Westerville, Ohio, has developed a $150 home gadget that actually transmits sounds as vibrations through your body, starting from the bottom up. The product's name says it all: the ButtKicker Gamer. This gizmo attaches to the bottom of your chair and sends low-frequency sound waves from music or games through the chair's back and, especially, its seat -- hence the name."
