ABSTRACT:
An adjustable speaker system includes a speaker enclosure having at least a forward facing surface, the speaker enclosure enclosing a speaker with a forward facing acoustic outlet from which sound may emanate in a forward direction. The system further includes at least one reflector, and preferably a pair of independently adjustable reflectors, with a sound-reflecting rearward facing surface, each reflector being pivotably secured adjacent the acoustic outlet and pivotable relative to the acoustic outlet between a non-reflecting orientation wherein the sound-reflecting rearward facing surface is substantially in alignment with the forward direction, thereby to only minimally reflect sound emanating from the acoustic outlet, and a reflecting orientation wherein the sound-reflecting rearward facing surface is substantially angled to the forward direction, thereby reflecting impinging sound emanating from the acoustic outlet laterally to a respective side.
