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 8 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.

- 8 Reference plane is the plane coincident with the loudspeaker baffle plane. Reference axis is the axis perpendicular to the reference plane and passing through the center of the baffle. Vertical plane is the plane intersecting the reference plane at a right angle, including the reference axis and the taps selector knob. Horizontal plane is the plane intersecting the reference plane and the vertical plane at a right angle, including the reference axis.
