Key Features
Porta-Fi System: The SP46 was designed to be part of GE's "Porta-Fi" concept, allowing users to place an extension speaker in a different room or area to extend the stereo sound field from a main console unit.
Integrated Amplifier: Unlike passive speakers, the SP46 has its own built-in amplifier, which requires it to be plugged into a wall outlet to function.
Monaural Output: It typically provided a single channel (often designated "Channel B") sound extension from the main stereo unit.
