I have 2 of the DIYMA Reference 12 subwoofer drivers available. Paid $200 for them in May 2009. I will sell both for $75 plus shipping. 1 is in orig shipping box never opened, the other I evaluated for a very short period but it's not even really broken in (maybe 2 hrs on it). Drivers only (no boxes, amps, etc).
Below is a link to a thread on them from the DIYMA site (pics and plots):

Some comments from DIYMA users:
“The sub plays very quick, and snaps tight. It was able to keep up with the Dream Theaters double bass drums with no problem. You can tell that there is a sub however it was transparent enough to make you wonder because the placement of the sub was rather hard to localize, even at high volumes.”” –Skylar112
"I can understand why it is called the Diyma "Reference" because of the natural transparent sound that it produces. It blends better with my front stage than any other sub that I have owned or tried. I have not done any eq work whatsoever and may not. This sub makes you forget that you have something in the trunk when listening at normal levels. This sub will have a place in my car as long as it lasts." -Legend94
“The sub has no signs of sloppiness at all, I noticed that this sub is buttery smooth.” -Dual700
“This sub is overbuilt for the purpose, and I love it. Dual faraday rings to cut distortion in the motor making it the cleanest sub i've heard” –Demon2091tb
“I was really impressed with the SQ and the output at 400-500 watts.” - Hawkfan

"I just got mine today and I've had over 15 or so "Super" Subs and this is hands down the best SQ i've found in a subwoofer. Everything is so effortless and it does not miss a beat (literally)." - Jayrich
