Detailed Description Cuboid 5
Cuboid 5 is a two-way loudspeaker for background music and speech in distributed installations. A 5.25-inch coated-paper LF driver works with a 0.75-inch silk-dome tweeter and shallow waveguide. The specified coverage pattern is 130° horizontally by 120° vertically.

The ABS enclosure is supplied with a wall bracket for portrait or landscape mounting. An optional weatherproof terminal cover is required to achieve the IP54 rating outdoors. The speaker has a nominal impedance of 8 Ω and handles 50 W AES.
SmartAmp or a suitable powered Zone controller provides amplification and loudspeaker protection through the supported presets. A compatible Sub loudspeaker extends bass reproduction where required. Source routing and staff control are available through Zone and WebApp, with optional ZonePad panels around the venue.
