TH-4A4

The TH-4A4 all-aluminum speaker combination can be used with any of the four speaker head units of the MT-35/60/TU-35/60/100/ML series.
It has passed the IP66 waterproof certification and has high sensitivity, long sound transmission, high efficiency, and clear sound range performance;
Widely used in public places such as airports, churches, ships, propaganda vehicles, etc., PA speaker products can also be used as a component of the voice alarm system to provide alarms to people in or near buildings where fire emergencies occur, and enable these people to take predetermined measures according to the evacuation plan.

When mounting four driver units to the TH-4A4, make sure that units are of the same model number.
If they differ in model number or power handling capacity, sound interference may occur, resulting in distorted sound or, at worst, speaker failure.
