I took a tour of the back of an ,IMAX theater last weekend,amazing! The one screen had 1.5 tons of speakers, with 8 18-inch (SONIC) Subs, enclosed in fiberglass cabinets. Every seat also had a "Guitammer-Buttkicker" under it for that added thump!
My question is since the Buttkicker only costs $190, is it worthwhile to stick one behind my favorite chair, or is it overkill. And does anybody have one?
