Optimal Audio Cuboid 8
Two-Way Passive
Ful-Range 8” loudspeaker
The Optimal Audio Cuboid 8 is a high-performance full-range passive loudspeaker, designed to deliver powerful, detailed sound in medium to large commercial environments. Ideal for hospitality, retail, and leisure venues, it offers excellent coverage, flexible installation, and reliable performance for both background music and higher output applications.
Description
Cuboid 8 is a full range, two-way, passive, 8” loudspeaker designed to outperform its compact size. For short to medium throw distances, it effortlessly delivers rich and detailed sound with punch and precision.
With its wooden cabinet, steel grille and optional mounting hardware the professionally presented Cuboid 8 can be fixed in either portrait or landscape mode for a flexible, simple installation.
Cuboid 8 features an 8” (200mm) low frequency (LF) driver for impressive punch and midband with a 1″ (25mm) exit high frequency (HF) compression driver for clarity of vocal and high frequency projection. The HF section delivers consistent coverage in either plane from a user-rotatable horn.
For enhanced bass performance, Cuboid 8 can be teamed with Sub 10 or Sub 15.
SmartAmp will provide amplification, optimal sound settings as well as limiters to protect the drivers when playing at louder sound levels.
When coupled with Zone and WebApp, system set up and end user control is easy, and can be further enhanced by ZonePad wall controllers.
