The Revel B15 was a FABULOUS sub. Can't wait to get the 30.

I think you actually have to go to 7.623654hz to do that.

only if it is powered by 1.21 gigawatts
Now they show you how detergents take out bloodstains, a pretty violent image there. I think if you've got a T-shirt with a bloodstain all over it, maybe laundry isn't your biggest problem. Maybe you should get rid of the body before you do the wash.

That one literally had me lauging out of my pants. Although I though it was spelled "One point twentyone jiggawattz"

Either way, those subs look to cost around the same price as a suitcase of Plutonium from a bunch of Libyan Nationals

Personally, I cannot wait for Nicholas to get the first used Sub30. Nicholas... Question, If the Revel can actually deliver 275 ^3 inches per stroke, what will its maximum output be at 16 Hz, anechoic ?

Craig, baiting is beneath you don't you think? It's most unattractive and doesn't inspire credibility.
