Abstract: A system for providing the effect of an extended soundstage comprises a pair of stereophonic loudspeakers, each having a movable or vibrational element driven by a pair of voice coils including a principal or main voice coil and an auxiliary or enhancement voice coil. The principal voice coil of each speaker is driven in a customary manner from one channel of a stereophonic amplifier, while the enchancement voice coil is driven in a reversed phase sense from the output of the opposite channel, and sound is effectively provided over an extended apparent source having dimensions beyond the spacing between the loudspeakers.
