The Bose 402 offers superior performance without the bulk of conventional professional loudspeakers. Four proprietary 4.5-inch (11.4cm) full-range drivers and active EQ help reproduce vocals and acoustic instruments with clarity and detail.

An acoustic diffractor broadens and smoothes the sound pattern for more uniform, even coverage from slim, light-weight loudspeakers. A proprietary Articulated Array speaker configuration positions the drivers for broad horizontal and narrow vertical dispersion.

Panaray 402 loudspeakers are engineered to withstand environmental extremes: blistering heat to frigid cold, dusty air to dense fog. They can endure harsh conditions like wind, rain, snow and sleet.
