mtx 9500, DD 9500, adire brahma, re xxx, mmats juggers., C.V stroker, big treos, the JL Weiner7, shockers, rp-l, solo x, and many many more
ALL BIG WOOFERS THAT WILL KICK ASS IF INSTALLED RIGHT (good box, right amount of power, and some tender love and care)
they are all pretty much on the same level, some have a lil more SPL than SQ, or vise versa.It all depends on what you're looking for in a woofer, it's almost impossible to say which is better than the other...no need to knock on other ppl's setups
......unless it's an audiobling setup, then it's ok to throw rotten eggs at their heads lol
and IMO xxx,brahma, DD9915, and shockers are amoung the best...
