Blueprint's site is
www.blueprintdrivers.com but it's been down for a while.
Take a look at this sub:
12" Dayton DVC It's a clone of the Adire Audio Shiva, which has gotten rave reviews.
I'm designing a system for someone and will be using either the 12" or 15" Dayton DVC powered by a 2ch amp in bridged mode (possibly a US Acoustics USX-2150 producing 450w for around $125).
