Abstract
A balanced armature apparatus is disclosed that includes dual transducers for generating sound waves in response to electric audio signals. The dual transducers include a motor assembly coupled to a diaphragm. A housing defines an interior chamber and the motor assembly and the diaphragm are positioned within the interior chamber. A pair of acoustic output ports is located in a respective end of the housing. A low pass acoustic filter is in communication with one of the acoustic output ports that is operable to attenuate a predetermined range of frequencies from an audio signal produced by one of the diaphragms.
