Meyer Sound UPM-2P Self-Powered Loudspeaker
The Meyer Sound UPM-2P is a remarkably compact, self-powered professional sound reinforcement loudspeaker system. It is ideally suited to applications requiring a relatively small and inconspicuous loudspeaker that can also provide high sound pressure levels, extremely low distortion, and uniform directional control.
