Pricing seems a little high...and what's with the +/-6db on the 13 & 16? That 16 isn't little either. I wonder if a non-DIY ported sub of basically the same size would/could output the same volume and quality for less money? We'll have to wait and see if the SVS track record holds up. Let's hope so for the non-DIY crowd.
I'm sure they will perform well but if I need something(s) small and powerful I'll PM WmAx and DIY something for a lot less. (Leave it alone Alex!
