Well, it's all about timing, I guess. I just saw the post mentioning the ButtKicker and now this.
So is this the latest craze? I can't see using them for music at all. Has anyone used these? I have tremendous difficulty imagining how these could be anything other than moderately amusing for longer than five minutes.
I sat in a theater at a local shop recently... the seats all moved to the movie (a spearate CD in a special player, sync'd to the movie you are watching). Dude put in LOTR when Gandolf was fighting that hell beast thingy. Was nutz!
I have a SVS PB2-Plus, it's gain is below half way, and I can shake the entire room wonderfully, the couch feels like you're getting sacked in the kidney, it's lovely.
