That is $150 cheaper than what I could find locally. I wish I had the money to switch out my sub.

actually, that's a damn good price. the best i found was around that $650 mark, but shipping to hawaii would be a bitch cause that sub is frickin' heavy! locally here it's about $650, but you have to buy the first one at $750 b4 you get the "discount"...
