The TOA BS-1034 Wall Mounted Speaker is powered by 70 or 100 volts, has a 10 watt rating, and produces full sound for commercial use while staying low-profile and unobtrusive. With a 5" driver and a high-frequency dome tweeter, the public address system is a two-way design. Installation is simple thanks to the M4 screw barrier strip connector, speaker receptacle, and wall mounting screws.
