ABSTRACT OF THE DISCLOSURE A speaker assembly of an emergency signalling system is provided having means recessed below the face plate of the speaker assembly for easily adjusting the power tap settings of audio signals of the speaker assembly. The speaker assembly fits into a wall cavity and receives and modifies audio signals at variable discrete levels of power in response to a power source. The assembly includes a speaker element having a diaphragm and a magnet assembly, and an interface for coupling power from the power source to the magnet assembly of the speaker element. The power interface includes a variable coupling having a plurality of settings providing variable levels of power to the magnet assembly from the power source. A face plate is mounted over the diaphragm of the speaker element for closing the wall cavity after the speaker element and power interface have been received by the wall cavity. The means recessed below the face plate is operable for selecting one of the settings of the variable coupling in order to adjust the volume of the audio signal without removing the assembly from the wall cavity or without having to externally mount additional adjustable transformer assemblies.
