Abstract
An audio processing module (20) capable of virtually infinite segmentation of the audio frequency spectrum. The module (20) comprises a first submodule (22), a second submodule (24) and a subwoofer module (28). The first and second submodules (22, 24) are substantially identical, each containing a high pass signal path (112), a high pass band signal path (114) and a low pass band channel (116). A mixed input/output port (29) provides a means for serial chaining of multiple modules.
