You can get blueprint from
www.blueprintdrivers.com but their website is down right now. I've heard great things about the other mentioned subs from people on this forum. i myself just recieved a blueprint 1001 yesterday and it's getting installed in the morning. I can say this, it makes my old jl 10w6 sub look like shat, and I paid less than half of what the jl cost me. I'll post the results tommorow as soon as it's installed. I'm sure dave can enlighten you further about some other subs that are reasonably priced yet have great performance.
