Do you think they would sound much better than the Beyma I posted earlier??Ive heard a set of Beyma, and they are pretty sweet,with only 75rms is what I heard them @
Nah, I've seen them used in several different 2 way setups with pretty flat response up to ~1.5k. They're more suited in a three way setup I guess, but they're far from solely a subwoofer.
Of course, that's in a cabinet, inside a house. Regardless, you'd probably want to have it passed at 1-1.5k. I'd be willing to bet that the Anarchy would sound as good as anything else mentioned so far.
