I was looking for reviews because it seems like a great price for a sub, and found this review hillarious (but also disconcerting):

"I like everything about this woofer, except the fact that--when it goes into power-saving "sleep" mode--it lets out a loud sound that my wife says is a snore, but I say it's a fart. Either way, we're returning it, since it wakes us up when we've fallen asleep during the music, and it emits this loud-but-odorless flatulence every 10 minutes or so when we've got the volume of the music down low.
