Cuboid 15 is a full range, two-way, passive, 15” loudspeaker designed to perform. For any applications requiring big output, it effortlessly delivers rich and detailed sound with extra punch and precision.

With its wooden cabinet, steel grille and optional mounting hardware the professionally presented Cuboid 15 can be fixed in either portrait or landscape mode for a flexible, simple installation.

Cuboid 15 features a 15” (380mm) low frequency (LF) driver for extra bass 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 15 can be teamed with Sub 15.

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