EN 54 24 Wall Mount Speaker 50W


A51T is a compact, two-way, surface-mount loudspeaker system designed for constant-voltage or constant-impedance applications. It is equipped with a 76 mm (3”) woofer and a 1” dome tweeter, able to provide an excellent speech intelligibility with wide dispersion, together with a very good background music reproduction.

A51T features a transformer to operate on 100V and 70V constant voltage systems. In a sealed compartment on the rear panel, together with the rotary selector for power taps or impedance, it includes, in compliance with EN 54-24:2008, a ceramic terminal block and a thermal fuse and it is, therefore, suitable for the use in voice alarm systems.

The ABS cabinet complies to UL 94V0 and is available in black (A51TB) or  white (A51TW) color finishing, allowing the best décor matching in any environment.

The IP55C environment protection allows the A51T speaker to be installed both indoors and outdoors.
