Octoid & Quadoid
Coming soonOctoid & Quadoid loudspeakers
Broadband containment in a compact form — coming soon.
Loudspeakers that control where sound does not go. Quadoid radiation confines sound to a quarter-sphere, Octoid to an eighth, across the full audio band. Launch timing and final specifications to be announced.
- Quadoid — sound confined to one quarter of a sphere
- Octoid — sound confined to one eighth of a sphere
- Localised, personal listening without headphones

Octoid and Quadoid loudspeakers are designed to control where sound does not go. They provide broadband, three-dimensional containment in a compact form, achieving spatial control that conventional omnidirectional, directional or cardioid patterns cannot match across the full frequency range.
The technology is not yet launched. Read the technology preview and register interest to be notified.
