Optimal Audio Cuboid 8-B

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 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) ow 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.

When coupled with the Zone series, a ZonePad and the WebApp makes setting up a system and end user control simple and intuitive.
