The AcousticDesign™ Series AD-S402T is a 4-driver column surface-mount loudspeaker. This premium full range system is capable of 70 V / 100 V or 16 ohm bypass loads, making it ideal for a wide variety of foreground and background applications with acoustically challenged environments. Equipped with a unique pan/tilt mounting system, the column surface-mount loudspeakers offer multiple positioning locations allowing the loudspeaker to remain close to the wall while delivering up to -20° downward tilt.
