Abstract
A wall mounted speaker system which is arranged to alleviate problems of unwanted noise in the production and transmission of audio waves, particularly in the lower wave lengths from 20 to 200 hz. There is a speaker unit having a pair of vertically spaced speakers, and an inertial noise suppressing section positioned between the two speakers. The inertial noise suppressing section has an inertial mass which is moved in a back and forth motion to create an inertial offsetting force into a housing structure of the speaker section. The two speakers also create inertial forces which are also transmitted into the housing of the speaker unit, and these are substantially diminished by the interaction of the inertial forces of the speakers and those of the inertial noise suppressing system.
