That would be loud, BUT HUGE, I have a big house, and I wouldn't have room for that lol...
A friend of mine has 2 EV 1122's {I think they are 500w each, and the k12's are easily double that each}, and an EV sub, all hooked to a DAC and Ipad.. He uses it outside for big parties... It is loud, I couldnt picture it inside a house...
