Uni-Q® technology: precision-engineered for outdoors
For the first time, KEF's renowned Uni-Q® technology is available in an outdoor speaker range. The bespoke weatherproof 6.5-inch and 8-inch Uni-Q® driver arrays are optimised for open-air environments, ensuring weather resistance without compromising performance. The larger speaker drivers offer greater efficiency and reduced distortion, ensuring expansive coverage and consistent performance even at higher volumes.

By positioning the tweeter precisely at the acoustic centre of the bass and midrange cone, Uni-Q® technology creates a single point source that delivers smooth, even sound dispersion. The result is a controlled, wide sound field that immerses everyone in high-fidelity sound, wherever they are in the outdoor space.

Powerful bass beyond walls
BQ9 and BQ11 feature long-throw drivers engineered for powerful, articulate low-frequency reproduction. An expertly tuned acoustic system achieves exceptional air-volume displacement while minimising distortion. The acoustically optimised design delivers consistent, full-bodied bass even in expansive outdoor spaces.

BQ9 and BQ11 feature an internal passive crossover, allowing them to pair with your preferred amplifier and deliver true HiFi sound outdoors, just like a traditional HiFi speakers but built for all-weather durability.

This three-way configuration separates frequency ranges for optimal clarity: the Uni-Q driver handles high and midrange frequencies, while the dedicated bass driver delivers deep, dynamic low frequencies. By optimising each driver for its role, the system reduces distortion and enhances detail, creating a rich, balanced sound with an expansive soundstage.

enclosures designed for long-lasting performance. Each speakers features an aluminium grille that shields the drivers from outdoor exposure, while the UV-resistant design ensures resilience against prolonged sunlight exposure.
