A full \u003cstrong\u003e360-degree coverage pattern\u003c\/strong\u003e helps distribute low frequencies evenly, allowing the subwoofer to integrate naturally with KEF bollard speakers and landscape satellite speakers.\u003c\/p\u003e\n\u003cp\u003eWith an \u003cstrong\u003eIPX5-rated weather-resistant enclosure\u003c\/strong\u003e, UV-resistant construction and flexible mounting options, the BL8b is engineered for permanent outdoor installation throughout the year.\u003c\/p\u003e\n\u003ch2\u003e200mm Long-Throw Bass Driver\u003c\/h2\u003e\n\u003cp\u003eThe KEF BL8b features a \u003cstrong\u003e200mm or 8-inch long-throw low-frequency driver\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIts long-throw design allows the driver to move a greater volume of air, providing the controlled output needed to reproduce bass effectively in open environments. The result is full-bodied low-frequency performance without sacrificing clarity or definition.\u003c\/p\u003e\n\u003cp\u003eThe driver operates across a frequency range of \u003cstrong\u003e25Hz to 330Hz at −10dB\u003c\/strong\u003e, giving music and outdoor entertainment systems greater depth, weight and impact.\u003c\/p\u003e\n\u003ch2\u003eDeep, Articulate Bass Beyond the Listening Room\u003c\/h2\u003e\n\u003cp\u003eOutdoor areas lack the walls and boundaries that reinforce bass inside a conventional listening room. The BL8b compensates for this with its high-excursion driver and carefully tuned acoustic enclosure.\u003c\/p\u003e\n\u003cp\u003eIt adds convincing low-frequency energy to music while maintaining a controlled and balanced presentation. Whether used for relaxed background listening or more energetic outdoor entertainment, the BL8b helps create a fuller and more immersive sound.\u003c\/p\u003e\n\u003ch2\u003e360-Degree Bass Coverage\u003c\/h2\u003e\n\u003cp\u003eThe BL8b provides \u003cstrong\u003e360-degree nominal coverage\u003c\/strong\u003e, allowing bass to spread evenly around the subwoofer.\u003c\/p\u003e\n\u003cp\u003eBecause low frequencies are distributed in every direction, the BL8b can serve a broad outdoor area without needing to face a specific listening position. Its nominal coverage area of \u003cstrong\u003e120 square metres\u003c\/strong\u003e makes it suitable for patios, pool surrounds, landscaped gardens and other sizeable outdoor spaces.\u003c\/p\u003e\n\u003ch2\u003eMaximum Output of 109dB\u003c\/h2\u003e\n\u003cp\u003eWith a rated maximum sound pressure level of \u003cstrong\u003e109dB\u003c\/strong\u003e, the BL8b can deliver substantial bass output for residential and selected commercial outdoor installations.\u003c\/p\u003e\n\u003cp\u003eIts combination of output, low-frequency extension and wide coverage makes it suitable for supporting multiple outdoor speakers within a professionally designed audio system.\u003c\/p\u003e\n\u003ch2\u003eDesigned for KEF Network DSP Amplifiers\u003c\/h2\u003e\n\u003cp\u003eThe BL8b is designed for use with compatible \u003cstrong\u003eKEF Network DSP Amplifiers\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eKEF recommends \u003cstrong\u003e150 watts of amplifier power\u003c\/strong\u003e and a \u003cstrong\u003e170Hz low-pass filter\u003c\/strong\u003e. DSP-based amplification helps integrate the subwoofer with the accompanying outdoor speakers while providing the appropriate crossover, equalisation and system protection.\u003c\/p\u003e\n\u003cp\u003eSystem configuration should be completed by an experienced installer to ensure correct performance and dependable operation.\u003c\/p\u003e\n\u003ch2\u003eIPX5-Rated Weather Resistance\u003c\/h2\u003e\n\u003cp\u003eThe KEF BL8b is certified to \u003cstrong\u003eIPX5\u003c\/strong\u003e, providing resistance against water jets from any direction.\u003c\/p\u003e\n\u003cp\u003eIts rugged, weather-sealed enclosure helps protect the internal driver against rain, moisture and other conditions encountered during permanent outdoor use.\u003c\/p\u003e\n\u003cp\u003eIPX5 does not mean the subwoofer is waterproof or suitable for immersion. It should be positioned where it cannot become submerged or remain in standing water.\u003c\/p\u003e\n\u003ch2\u003eUV-Resistant Outdoor Construction\u003c\/h2\u003e\n\u003cp\u003eThe BL8b uses UV-resistant materials to help protect its exterior against prolonged sunlight exposure.\u003c\/p\u003e\n\u003cp\u003eIt is designed to operate across temperatures ranging from \u003cstrong\u003e−25°C to +70°C\u003c\/strong\u003e, allowing it to accommodate demanding seasonal conditions.\u003c\/p\u003e\n\u003cp\u003eKEF has also subjected the enclosure to more than \u003cstrong\u003e500 hours of salt-spray testing\u003c\/strong\u003e, supporting installation in coastal and salt-laden environments when the subwoofer is correctly installed and maintained.\u003c\/p\u003e\n\u003ch2\u003eDurable Aluminium Grille\u003c\/h2\u003e\n\u003cp\u003eA one-piece aluminium grille wraps around most of the upper enclosure.\u003c\/p\u003e\n\u003cp\u003eThis grille shields the driver from outdoor exposure while helping sound disperse evenly around the speaker. Its refined finish and minimalist form allow the BL8b to blend unobtrusively into contemporary gardens and architectural landscapes.\u003c\/p\u003e\n\u003ch2\u003eFlexible Outdoor Installation\u003c\/h2\u003e\n\u003cp\u003eThe BL8b supports several mounting arrangements for different outdoor environments.\u003c\/p\u003e\n\u003cp\u003eInstallation options include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGround-stake mounting in landscaped areas\u003c\/li\u003e\n\u003cli\u003eHard-surface installation on patios or concrete\u003c\/li\u003e\n\u003cli\u003ePartially buried installation for a more discreet appearance\u003c\/li\u003e\n\u003cli\u003eInstallation beneath timber decking\u003c\/li\u003e\n\u003cli\u003eCompatible wood-deck mounting accessories\u003c\/li\u003e\n\u003cli\u003eDirect mounting beneath compatible KEF bollard speakers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWith the standard ground stake, the BL8b measures \u003cstrong\u003e1056mm high\u003c\/strong\u003e.
