KEF - BQ11 - Outdoor Speaker

KEF BQ11 Three-Way Outdoor Bollard Speaker High-Output Outdoor Speaker with Integrated 12-Inch Bass The KEF BQ11 Three-Way Outdoor Bollard Speaker combines an 8-inch Uni-Q driver array with a powerful 12-inch long-throw bass driver to deliver expansive, full-range sound across large outdoor spaces. Its integrated three-way design reproduces detailed high frequencies, natural midrange and deep bass from one elegant, weather-resistant enclosure. A maximum output of 112dB and low-frequency extension down to 23Hz make the BQ11 ideal for ambitious residential, hospitality and commercial landscape audio systems. With IPX5 protection, UV-resistant materials and flexible installation options, the BQ11 is built for reliable year-round outdoor performance. Three-Way Full-Range Performance The BQ11 uses separate high-frequency, midrange and low-frequency drivers to reproduce each part of the audio spectrum accurately. Its driver configuration includes: 19mm high-frequency driver 200mm Uni-Q midrange driver 300mm long-throw bass driver An internal passive crossover separates the frequency ranges and directs them to the appropriate drivers. This creates a balanced, full-range presentation while allowing the speaker to connect to a suitable conventional amplifier. 200mm Uni-Q Driver Array The BQ11 features a large 200mm or 8-inch Uni-Q driver array optimised for outdoor environments. KEF’s Uni-Q technology places the tweeter at the acoustic centre of the midrange cone. This arrangement creates a coherent sound source with smooth, controlled dispersion. Listeners experience consistent detail, clarity and tonal balance across the outdoor area, even when they are positioned away from the speaker’s central axis. Integrated 300mm Bass Driver A dedicated 300mm or 12-inch long-throw bass driver provides the BQ11 with substantial low-frequency output. The high-excursion driver is engineered to move the volume of air required to reproduce deep bass in open spaces. Its acoustically optimised enclosure maintains articulation and control while minimising unwanted distortion. With a frequency range extending down to 23Hz at −10dB, the BQ11 adds impressive weight and impact to music, films and outdoor entertainment. Designed for Large Outdoor Areas The BQ11’s larger drivers and greater output make it suitable for expansive gardens and high-performance outdoor installations. Its 100-degree nominal coverage pattern focuses sound across the intended listening area, while a maximum output of 112dB provides the headroom needed for larger spaces. Several BQ11 speakers can be strategically positioned throughout a property to achieve consistent coverage without relying on excessive volume from one location. True Outdoor Stereo Sound A pair of BQ11 speakers can be connected as separate left and right channels to create a genuine outdoor stereo system. This arrangement adds dimensional depth, precise spatial placement and a broader soundstage. It is particularly valuable for dedicated outdoor listening areas and open-air cinema systems where more immersive reproduction is desired. IPX5-Rated Weather Resistance The KEF BQ11 is certified to IPX5, providing resistance against water jets from any direction. Its weather-sealed enclosure helps protect the drivers and crossover against rain, moisture and typical outdoor exposure. The BQ11 is not designed for immersion. Suitable drainage must be provided, and the enclosure should not be installed in an area where it may remain in standing water. UV-Resistant Outdoor Construction UV-resistant materials help the BQ11 withstand prolonged exposure to direct sunlight. The speaker can operate across temperatures ranging from −25°C to +70°C, supporting dependable performance through substantial seasonal changes. More than 500 hours of salt-spray testing further support its use in demanding coastal environments, subject to appropriate installation and maintenance. Refined Aluminium Grille A one-piece aluminium grille covers most of the upper speaker enclosure. The grille provides a durable protective barrier while allowing sound to disperse effectively. Its refined finish and understated tower design help the BQ11 integrate into premium landscaped areas without appearing visually intrusive. Flexible Placement and Installation The BQ11 supports several permanent mounting arrangements. Installation options include: Ground-stake mounting in landscaped areas Partial burial for discreet integration Hard-surface mounting on patios or concrete Placement on other suitable structural surfaces Without a mount, the BQ11 measures 1168mm high. Its total height increases to 1453mm when installed with the ground stake. Build a Scalable Outdoor Audio System The BQ11 can operate as a standalone full-range speaker, as one half of a stereo pair or as part of a broader KEF outdoor audio system. Different KEF bollard speakers, landscape satellite speakers and outdoor subwoofers can be combined according to the size and layout of the property. This allows the system to grow from a single entertainment area to several independently controlled listening zones.
