KEF SR6Q 6.5” Uni-Q Outdoor Landscape Satellite Speakers (Set of 4)

For more than six decades, KEF has been driven by a pursuit of acoustic excellence. Now, that same devotion breathes into the open air. Building on the groundbreaking technologies behind our award-winning HiFi speakers, SR4Q and SR6Q outdoor landscape satellites integrate Uni-Q® technology into a rugged, weather-resistant and construction engineered for reliable performance in outdoor environments. Compact yet powerful, they deliver natural, detailed sound across gardens, patios and poolside spaces.

Designed to excel in all outdoor conditions, SR4Q and SRGQ feature IPGG-rated, UV-resistant, weather sealed enclosures that endure intense sunlight, heavy rain, coastal salt and extreme temperatures while delivering pristine sound season after season. Their sleek, minimalist silhouette integrates seamlessly into any outdoor setting, while versatile mounting options allow for effortless placement wherever required.

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 4.5-inch and 6.5-inch Uni-Q driver arrays are optimised for open-air environments, ensuring weather resistance without compromising performance. 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.

Built for all-weather durability
Engineered for year-round durability, KEF's outdoor speakers are housed in rugged, robust
enclosures designed for long-lasting performance. Each speaker features an aluminium grille that shields the Uni-Q driver from outdoor exposure, while the UV-resistant design ensures resilience against prolonged sunlight exposure. Withstanding temperatures from -25C to +70C and enduring over 500 hours of salt spray testing, SR4Q and SRGQ are built to thrive in extreme conditions and perform in even the most demanding outdoor environments. Certified to IP66, they are resistant to dust and water, delivering consistent acoustic excellence in the toughest weather.

Easy placement, seamless integration
Designed for maximum placement flexibility, SR4Q and SR6Q offer a variety of mounting
options, ensuring they can be seamlessly integrated into different outdoor environments.
Ground stakes enable landscape installation, while surface mounts allow secure placement
on walls, eaves, or trees. Optional Pendant Mount Kits are also available for overhead installation, making them ideal for wider sound coverage in high-ceilinged spaces.

Expertly tuned, elegantly crafted
Precisely tuned to KEF's unparalleled standards, SR4Q and SRGQ feature a minimal, organic form that is as highly refined as it is visually understated, seamlessly into natural surroundings while maintaining the impeccable fit and finish our products are renowned for. With a fluid silhouette the speakers feature a tone-on-tone aluminium grille, offering both durability and an aesthetic that echoes the underlying Uni-Q driver array.

Deep bass in the wide open
To complete your outdoor sound experience, BL8b and BL12b bollard subwoofers are also
available in the outdoor speaker range to bring low-frequency punch to your outdoor audio setup. Engineered for open-air performance, these subwoofers deliver rich, powerful bass that enhances the emotional impact of your entertainment across your outdoor space.

Mix, match and expand
The KEF outdoor speaker range offers a variety of models and system packages that allow you to mix and match components and expand your setup according to your needs. This flexibility allows for easy adaptation to any size of outdoor space, from intimate garden corners to expansive landscapes with multiple listening zones, including poolside, patio and padel courts.
