ABSTRACT:
An improved speaker enclosure system and method is described which includes extending the existing baffle of a speaker enclosure on either side. Ideally, the ratio of the height of the baffle should be 1.4 times the internal depth of the enclosure, and the width of the baffle and baffle extensions should be 1.6 times the internal depth. These ratios change for different driver configurations. The result is improved dispersion angle and perceived dimensionality of the sound produced.
