KEF - SR4Q - Outdoor Satellite Speakers

KEF SR4Q Outdoor Landscape Satellite Speaker Compact Outdoor Speaker with Uni-Q Technology The KEF SR4Q Outdoor Landscape Satellite Speaker brings detailed, evenly distributed KEF sound to gardens, patios, pool surrounds and landscaped outdoor areas. Its compact enclosure incorporates a weatherproof 4.5-inch Uni-Q driver array, engineered to produce clear and natural sound across a wide listening area. Multiple mounting options allow the SR4Q to be installed in garden beds, attached to structural surfaces or suspended overhead using an optional pendant-mount kit. With IP66 protection, UV-resistant materials and a rugged weather-sealed enclosure, the SR4Q is designed for permanent, year-round outdoor audio installations. 4.5-Inch Uni-Q Driver Array The SR4Q features a purpose-built 4.5-inch Uni-Q driver array optimised for open-air environments. KEF’s Uni-Q technology positions the tweeter at the acoustic centre of the bass and midrange driver. This creates a more coherent sound source and enables audio to disperse smoothly across a broad listening area. The result is balanced sound with clear vocals, precise detail and consistent tonal quality, even when listeners are positioned away from the speaker’s central axis. Wide, Consistent Outdoor Sound Outdoor spaces require more even sound distribution than conventional indoor rooms. The SR4Q’s Uni-Q driver produces a controlled, wide sound field that allows music to remain consistent as people move through the garden or entertaining area. Multiple speakers can be distributed throughout the landscape to maintain comfortable volume levels without relying on one speaker playing excessively loudly. Its compact size makes the SR4Q particularly suitable for smaller gardens, courtyards and areas where discreet integration is important. IP66-Rated Weather Protection The KEF SR4Q carries an IP66 rating, confirming complete protection against dust ingress and resistance to powerful water jets. Its rugged, sealed construction helps protect the internal components against: Rain and water spray Dust and airborne particles Prolonged sunlight Coastal air Changing seasonal temperatures The speaker is not designed for immersion and should not be installed where it may remain submerged or surrounded by standing water. Built for Year-Round Outdoor Use The SR4Q is engineered to operate across temperatures ranging from −25°C to +70°C. Its UV-resistant exterior helps reduce deterioration and discolouration caused by prolonged sunlight exposure. The design has also undergone more than 500 hours of salt-spray testing, supporting installation in coastal environments when correctly installed and maintained. Durable Aluminium Grille A tone-on-tone aluminium grille protects the Uni-Q driver against outdoor exposure. The grille contributes to the speaker’s durability while preserving its smooth, understated appearance. Its acoustically transparent design allows sound to pass through clearly and disperse effectively across the outdoor area. Ground-Stake Installation The SR4Q can be positioned in garden beds and landscaped areas using a compatible ground stake. Ground-level placement allows the speaker to blend naturally among plants and other landscape features. Its sound can then be directed towards the required listening zone while keeping the audio hardware visually discreet. Surface-Mount Installation A compatible surface mount allows the SR4Q to be attached securely to suitable walls, eaves, posts or other structural surfaces. This option is useful for patios, courtyards and outdoor entertaining areas where ground installation is not practical. The adjustable design allows the speaker to be aimed towards the preferred listening position. Optional Pendant Mounting For overhead installations, the SR4Q is compatible with the optional KEF SR-4PM Pendant Mount Kit. Pendant mounting can help provide wider coverage across entertaining areas, covered patios and other open spaces. It also keeps the speaker away from garden beds and floor-level activity while maintaining an unobtrusive appearance. Pair with an Outdoor Subwoofer The SR4Q can be paired with KEF’s outdoor bollard subwoofers for deeper low-frequency performance. Compatible subwoofer options include: KEF BL8b Outdoor Bollard Subwoofer KEF BL12b Outdoor Bollard Subwoofer A dedicated subwoofer handles the lowest frequencies, allowing the landscape speakers to concentrate on clear midrange and high-frequency reproduction. This creates a fuller, more balanced outdoor listening experience. Build a Scalable Landscape Audio System Multiple SR4Q speakers can be distributed throughout an outdoor area to create consistent coverage across different listening zones. The wider KEF outdoor range allows landscape satellites, bollard speakers and outdoor subwoofers to be combined according to the property’s size and layout. This flexibility supports installations ranging from intimate courtyard systems to extensive multi-zone landscape audio.
