Anyone out there tried the Aura Bass Shakers I have two of them mounted in my sofa and turn them on when I want the "room" to shake during special effects. I read about them in another forum and found two of them locally in a used video games shop- paid 20.00 each.
They come in a vest that is made for video gamers to wear to help "feel" special effects. I ripped the "shakers" out of the vests, mounted them under my sofa(not the cushions) and hooked the small amps to an improvised mini RCA plug cable attached the lfe out of Sony SAWM40 sub. They are adjusted to shake the seat during strong special effects of an action type DVD. No they are not for music, just for fun. You can find them on Ebay- search "interactor"
