The Tc2000 is an excellent woofer, my brother has it and it has great SQ, and real good low end extension. It blends well with you mids, could be a lil better but if you already have some good mid bass this would be great, just set you lpf to 50 hz, and your golden.
As far as the price increase, all you have to do is call them up, tell them what you want but you don't get paid til the end of the month and im sure they will accommodate you. They've had that deadline listed on their website for 3 or 4 weeks now and are always extending it, but just call them
