Weighing in at 3.45 cu ft volume the port is tuned at 37Hz. L=24" W=20" H=12". Almost the golden ratio, but I didn't have enough room in my trunk for a 32" length. I am replacing the speaker with a JL 12W3V2.
The sub ***** bad. But with that sub in a good box it pounds pretty good for a single cone (sits in my daily driver so I need the trunk space). I couldn't beat the price though, only $75 for the sub from someone who blew it... I took it in to the place where he bought it at and low and behold it was warrantied... got a brand new one no questions asked. Best $75 DVC 12" sub I've every purchased.
