ABSTRACT:
A speaker enclosure for a stereophonic sound system is disclosed. The speaker is mounted in a chamber, the enclosure of which is connected to a tube of relatively long length and of circular cross-section. The construction is such that phase-inversion occurs so that the sound emanating from the rear of the speaker reinforces sound from the front of the speaker. The construction also substantially suppresses standing waves.
