Thirty years ago, filling a room with sound meant filling it with equipment.
It was an almost universal belief that you needed a large component system to create full, rich sound. That usually included enormous speakers, the rack of components required to power them and a complexity level every bit as sizable as the system itself.
Bose® research hinted at a better way, a solution that would provide full sound quality in a compact system without the need for components. Traditional approaches determined it couldn't be done, but tradition didn't account for revolutionary acoustic waveguide speaker technology.
