According to the Yamaha Sound Reinforcement Handbook, a fantastic uhgtoh very complex manual on sound reinforcement, I found this .. For example,consider a loudspeaker rated to handle 200 W continuous and 400 W peak. Clearly we must choose a 200 W amp in order to not exceed the peak power rating. On the other hand a speaker rated at 100 W continuous and 400 W peak can be driven by a 200 W amp as well, since we can assume the system will run with at least a 6 dB margin between the long term average and the short term peak level. From that I take that you can run 500 W to the B215XL. Especially since the reference to continuous power corresponds to the long term average of power sent to the speaker. A speaker rarely has a continuous' signal sent unless there is a malfunction or someone sets a beer on the keyboard keys and walks away .. you get the point. Signals are sent in bursts and it's the average' that is critical. Of course you don't want to exceed the Peak as that can blow' a speaker .. which really sucks during a gig.Also, on my QSC, and I assume your Behringer, you can dial back the output on the amp if you don't need' all that power just to be safe. Also I would not go under 260 W as underpowering a speaker can cause distortion and eventual speaker failure as well.Hope that helps .. Steve -2Was this answer helpful?
