Cuboid 5 is a full range, two way, passive 5” loudspeaker designed to give exceptional sound quality in a very small form factor, for distributed applications with high quality background music and speech reproduction.

With its attractive design and included mounting hardware, Cuboid 5 can be fixed in either portrait or landscape orientation for simple and flexible installation. A weatherproof terminal cover is available for outdoor use, bringing the rating to IP54.


Cuboid  features a 5.25” low frequency driver and a 0.75” silk dome high frequency driver mated to a shallow wave guide for consistent HF distribution.

For enhanced bass performance, Cuboid 5 can be teamed with Sub 10, and a SmartAmp or powered Zone will provide amplification, optimal sound settings as well as limiters to protect the drivers when playing at louder sound levels.

When teamed with Zone and WebApp, system set up and end user control is simple and intuitive, and can be further supplemented by ZonePad wall controllers.

The Cuboid 5 is a passive speaker and requires a separate amplifier to function. Optimal Audio offers amplifiers like the Amp series designed to work seamlessly with their Cuboid speaker range. The amplifier should have a compatible impedance rating (typically 8 ohms) and sufficient power output to drive the Cuboid 5 speakers effectively.
