The Bose 3-2-1 GSX is a home theater system that was introduced by Bose in the early 2000s. It consists of a 2.1-channel speaker system and a DVD player with integrated FM/AM tuner. The speakers are designed to provide surround sound experience without the need for rear speakers. The system uses Bose's proprietary Acoustimass technology to enhance low-frequency performance. The 3-2-1 GSX also includes a universal remote control for easy operation.
