I would also check out Power Accoustik. They have some really nice sounding subs. Heck you could probably go with one of their 10"s and would be what you are wanting

 

i think ive decided what ill do, i think im going to get the T110D4 i might not be able to afford 2 of these right away but 1 is of these is much stronger then most 12" subs i just had the chance to listen to one in person.
