I have owned the Bose system with (2) subs for about a year. We have two systems in our (3) piece band. The drums are also ran through the system. Don't be mistaken...this is not a woos system. We run electric guitars and the bass through front line amps. We then balance the drums (ran through a small 12 channel board-premix,the musical instruments, and the vocals. Oh, I forgot to mentioned we have used these outdoors as well. Sound degradation occurs around 100+ yards. Other than that, outstanding!
