its a monster. 600 watts @ 4ohms. with my abm 900 its just a beast and then some. this cabinet is great. its about half a ton and cosmetically its a real beaut. and the best thing is LOUD LOUD LOUD. im suprised the neigherboors havnet call the boys in blue. and from what im told, however i could very have gotten some sour info, im the first one in america (or one of the first) to have this cabinet.
