Bose, facing the challenge of bringing the theatre to everyone in their comfortable den chair, invented the amazing Direct/Reflection technology. Direct/Reflection technology is a method of delivering sound to the listener that gives the illusion of a live production. When Bose combines this technology with their well-known desire to keep speakers practically sized for the household, Bose Bookshelf speakers are born.The bookshelf speakers come in many different sizes and shapes to fit comfortably and with style in any room. The bookshelf speakers can also easily be angled and moved to provide optimization of the Direct/Reflection technology. Once installed, the listener can sit back and enjoy movie theatre quality sound in the groove of their favorite den chair.
