I've owned a Rockford T112D4 subwoofer (2006 version I think) for many years. I've had it in like three different vehicles and in several different boxes, from ported to sealed. I'm looking to switch to something else, probably a 10" sub that excels in smaller sealed and ported boxes. I would like to find a sub that has better SQ than the T1 but still has good output. I've looked at the SSA Demon, the Sundown E-Series and the Dayton HO. Does anyone have any suggestions on a 10" sub? I'd like to spend under $200 for the sub. Thanks.
