Hey OP I have the 12" version of that sub sitting new in box if your interested in buying it from me //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Specs
IMO it's between the RE SE and the Dayton SS (like linked above). The reason I have SE on the list is because of my person experience with them in my Durango. The low FS and the sound I know they are capable of makes them on the list.
For your price point and purpose, this driver is almost unbeatable. It works well in virtually any enclosure but shines in 6 to 8 cu.ft. tuned to about 15 to 18Hz. Sounds beautiful with music and movies, and doesn't require it's own circuit to be powered. Parts-Express.com:
