Full-Range 5" Loudspeaker
The Optimal Audio Cuboid 5 is a versatile full-range passive loudspeaker, designed to deliver clear, balanced sound in a wide range of commercial environments. Ideal for retail, hospitality, and leisure spaces, it offers flexible installation, stylish design, and reliable performance for both background music and speech.
Description
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.
