KEF BL12b 12" Outdoor Bollard Subwoofer

For more than six decades, KEF has been driven by a pursuit of acoustic excellence. Now, that same devotion breathes into the open air. BL8b and BL12b outdoor bollard subwoofers bring KEF's acoustic excellence into the open air, with long-throw drivers delivering powerful, controlled bass that transforms outdoor music and movie experiences. Designed to complement KEF's outdoor speaker range, they add impactful low-frequency energy across gardens, patios and poolside spaces.

Designed to excel in all outdoor conditions, BL8b and BL12b feature IPX5-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, contemporary silhouette blends naturally into landscaped environments.

Powerful bass beyond walls
The BL8b and BL12b feature 8-inch and 12-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 -25C to +70C and enduring over 500 hours of salt spray
testing, the BL8b and BL12b 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
A variety of mounting options ensures BL8b and BL12b bollard subwoofers can be seamlessly installed across different outdoor environments. They can be securely positioned in landscaped areas using ground stakes, with the option to partially bury the base for a more discreet look. For hard surfaces such as patios, decks, or concrete areas, hardscape mounts provide a stable solution. Alternatively, the optional BL-WDM Wood Deck Mounts allow for installation beneath wooden decking, making use of otherwise unused space. For those seeking a fully integrated system, KEF's bollard speakers in the same outdoor range can be mounted directly onto BL8b and BL12b bollard subwoofers. This configuration serves as both a mounting solution to achieve optimal listening height and a unified design that combines high-fidelity sound with deep bass performance for an elegant outdoor setup.

Expertly tuned, elegantly crafted
Precisely tuned to KEF's unparalleled standards, BL8b and BL12b are crafted to blend effortlessly into natural surroundings with a smooth, understated silhouette and a minimalist form. The tone-on-tone aluminium grille adds durability while giving the speakers a refined, sophisticated look that remains immaculate in any setting. Covering most of the upper section where the driver sits, the grille not only provides a premium finish but also enhances sound dispersion, delivering an immersive listening experience across open spaces.

Mix, match and expand
Pair the bollard subwoofers with our range of bollard speakers and landscape satellites. 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.
