MAX-Wall™. Auralex offers a wide variety of stand-mounted, interconnecting, expandable, acoustical treatment systems through our MAX-Wall series. MAX-Wall panels are 48'' wide by 20'' high by 4.25'' thick acoustical panels that can be mounted to standard microphone stands. Each panel has a male and a female end-lock that allows interconnectivity between panels. MAX-Stands are included with most MAX-Wall Kits. The stands include extenders that allow you to mount up to four (4) panels on each stand and clamps that allow you to adjust the height of the panels up to roughly eight feet.
