KEF - Landscape P4Q - Outdoor Speaker System

KEF Landscape P4Q 4.1 Outdoor Speaker System Complete High-Fidelity Landscape Audio System The KEF Landscape P4Q 4.1 Outdoor Speaker System delivers detailed, evenly distributed sound and powerful bass across gardens, patios, pool areas and outdoor entertainment spaces. This complete package combines four KEF SR4Q landscape satellite speakers, one KEF BL8b outdoor bollard subwoofer and a KEF KASA 2-250M Network DSP Amplifier. Extended dynamic range, precise DSP control and flexible mounting options make it a comprehensive solution for professionally installed outdoor audio. Built around KEF’s renowned Uni-Q technology, the Landscape P4Q produces wide, consistent sound without requiring large or visually intrusive conventional speakers. Landscape P4Q System Components The KEF Landscape P4Q 4.1 system includes: Four KEF SR4Q landscape satellite speakers One KEF BL8b outdoor bollard subwoofer One KEF KASA 2-250M Network DSP Amplifier Dedicated dynamic EQ Extended ground stakes Precision system tuning Together, these components create a coordinated outdoor system with clear high frequencies, natural midrange and deep low-frequency performance. Four SR4Q Landscape Satellite Speakers Each included SR4Q features a weatherproof 115mm or 4.5-inch Uni-Q driver array. KEF’s Uni-Q technology places the tweeter at the acoustic centre of the bass and midrange driver. This creates a coherent sound source that distributes audio smoothly across a broad listening area. Using four satellite speakers allows sound to be distributed throughout the landscape at comfortable levels. This provides more consistent coverage than attempting to fill the entire area with one or two speakers operating at excessive volume. Wide, Even Sound Dispersion The Landscape P4Q is engineered to produce an immersive outdoor soundstage across expansive open spaces. The SR4Q speakers provide controlled dispersion, helping vocals, instruments and high-frequency details remain clear as listeners move through the area. Each speaker can be positioned and aimed according to the layout of the garden, patio or pool surround. BL8b Outdoor Bollard Subwoofer Low frequencies are handled by the included KEF BL8b Outdoor Bollard Subwoofer. Its 200mm or 8-inch long-throw driver produces controlled, articulate bass while minimising unwanted distortion. Full 360-degree coverage distributes low frequencies evenly around the subwoofer, supporting a consistent listening experience across the outdoor area. The BL8b extends the system’s low-frequency performance to 25Hz at −10dB, giving music and films greater depth, weight and impact. KEF KASA 2-250M Network DSP Amplifier The Landscape P4Q is powered and controlled by the included KEF KASA 2-250M Network DSP Amplifier. Designed specifically for high-performance installed audio, the amplifier uses advanced Class D amplification enhanced by next-generation GaN technology. KEF’s Music Integrity Engine and premium AKM Velvet Sound digital-to-analogue architecture support accurate, natural and detailed reproduction. The KASA 2-250M supports single-ended and bridged operation, allowing it to adapt to different installation requirements and system configurations. Precision DSP System Tuning Dedicated digital signal processing controls the crossover, equalisation and operating range of the included speakers and subwoofer. This enables the SR4Q satellites and BL8b subwoofer to work together as one cohesive system. Dynamic EQ also helps maintain tonal balance and low-frequency performance across different listening levels. The system should be configured by a qualified installer to ensure its DSP settings, wiring and speaker placement suit the specific outdoor area. Expandable up to an 8.2 System The Landscape P4Q can be expanded as the outdoor audio requirements grow. Its flexible architecture supports expansion from the supplied 4.1 configuration to an 8.2 outdoor speaker system, allowing additional listening areas or larger landscapes to be covered. This scalability makes the system suitable for anything from one focused entertainment zone to a more extensive property-wide outdoor installation. All-Weather Outdoor Construction The included speakers and subwoofer are purpose-built for permanent outdoor use. The SR4Q satellite speakers feature IP66-rated protection, while the BL8b bollard subwoofer carries an IPX5 rating. Their weather-sealed enclosures protect the internal components against rain, moisture and demanding environmental exposure. The outdoor components also feature: UV-resistant exterior materials Durable aluminium grilles Operating temperatures from −25°C to +70°C More than 500 hours of salt-spray testing Construction suitable for demanding outdoor environments The speakers should not be immersed or installed in locations where water can accumulate around their enclosures. Flexible Landscape Speaker Placement The four SR4Q speakers can be installed in garden beds and landscaped areas using the supplied extended ground stakes. Their compact form allows them to blend naturally among plants and architectural features. Each speaker can be aimed towards the intended listening area for more precise sound coverage. Compatible surface-mounting options also allow the SR4Q speakers to be installed on suitable walls, eaves, posts or trees. Versatile Subwoofer Installation The BL8b subwoofer supports several placement methods. It can be: Positioned using a ground stake Partially buried for a more discreet appearance Installed on a compatible hardscape mount Positioned beneath suitable wood decking These options allow the subwoofer to deliver powerful bass without disrupting the visual character of the surrounding landscape. Refined, Discreet Outdoor Design The Landscape P4Q system is designed to complement rather than dominate its surroundings. The satellite speakers use compact, smoothly contoured enclosures with tone-on-tone aluminium grilles. The bollard subwoofer has a similarly understated finish that integrates naturally with modern landscaping and exterior architecture.
