I use the Behringer B112W powered speaker (1,000 watts) with my Roland BK-9 Keyboard. Would a Roland KC-200 keyboard amp and speaker give a better sound albeit perhaps not as loud. At home I play the Roland BK-9 through my Cambridge Audio amp to Klipsch 3 ways speakers. The sound is a good as headsets. But, when I'm out playing the keyboard for ballroom dancing through the Behringer B112W the sound is pretty ordinary.
