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, KEF Outdoor Speakers are engineered to enrich every outdoor moment with the power of high-fidelity sound, bringing music and movies from indoors to outdoors without compromise.

Landscape P4F 4.1 outdoor system combines four SR4F 4" full-range landscape satellites with an BL8Sb 8" bollard subwoofer, delivering clear, even coverage and controlled bass across your outdoor space.

Ideal for patios, decking areas and smaller gardens, the system offers the flexibility to expand into an 8.2 configuration or scale further to suit larger outdoor spaces as your needs evolve.

Designed to excel in all outdoor conditions, Landscape P4F is UV-resistant and weather sealed to withstand intense sunlight, heavy rain, coastal salt, and extreme temperatures, ensuring pristine sound season after season.

Refined sound for the outdoors
The 4" full range landscape satellites employ a compact full bandwidth driver to reproduce well balanced sound with accuracy in outdoor settings, supporting the system’s overall performance with clean, articulate output.

Powerful bass beyond walls
Bollard Subwoofer feature 8-inch 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.

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 subwoofer features an aluminium grille that shields the drivers from outdoor exposure, while the UV-resistant design ensures resilience against prolonged sunlight exposure.

Withstanding temperatures from -25°C to +70°C and enduring over 500 hours of salt spray testing, the BL8Sb are built to thrive in extreme conditions and perform reliably in even the most demanding outdoor environments. Certified to IPX5 , they are water resistant for reliable performance and consistent acoustic excellence in the toughest weather.

Easy placement, seamless integration
Designed for maximum placement flexibility, KEF outdoor speakers offer a variety of mounting options to suit different outdoor environments. The landscape satellites can be installed using ground stakes for placement within garden beds and landscaped areas, or mounted on walls, eaves, or trees using surface mounts. The subwoofer can be positioned securely with ground stakes, with the option to partially bury the base for a more discreet appearance. For hard surfaces such as patios, decks, or concrete areas, hardscape mounts provide a stable and reliable installation solution.

Expertly tuned, elegantly crafted
The tone-on-tone aluminium grille adds durability while giving the speakers a refined, sophisticated look in any setting. Wrapping around most of the speaker’s surface, the grille not only provides a premium finish but also enables wider sound dispersion, delivering an immersive listening experience across open spaces.
