"Two unique setup positions, extended (78.5"H) and collapsed (16.5"H), let you tailor the system's sound coverage for the room or event. For larger audiences, use the included loudspeaker extensions to elevate the array. For smaller gatherings and meetings, leave the array in its slot on the power stand and place the system on a tabletop."
