Get a Yamaha DXR15 if you want the powered speaker thing. Bass has an element of physical impact and limitations to it that very very few off the shelf powered speakers can handle. I tested them all and only the Yamaha could amplify a low b like a real bass amp. Keep n mind I'm comparing to a bass 115 combo of 300w power when I say this, no powered speaker will compare to a fridge. The physical aspect of bass tone and all that.
Says peak is 1100W. I'm suspect how they measure and quote peak vs how much power is really RMS available at say 100-1000Hz.
