Well I am a owner of a 10" MTX 6000 series. Ive blowen the voice coil already and am on my second one. If I would replace this one with yet another one, I would say no. The 12's are nice, but there are alot of excellent subs out there on the market. RF's you may even find cheaper than the MTX's, and sound quality is better. Good luck!
I run 6 8000 series 12"s for competition and I was impressed. Never settle for a step below..never. You will be happier with the 8000's. They sound cleaner and will not distort at higher levels of volume. **** crutch field........over priced bastards. Look on-line I found my subs for less then $160 each.
