A true three-way design, it combines KEF's 12th generation Uni-Q driver array fitted with Metamaterial Absorption Technology (MAT) with four 165mm (6.5 in.) hybrid aluminium bass drivers in a bass reflex cabinet. The result is a speaker capable of a frequency range from 30Hz to 50kHz, a maximum output of 113dB, and an in-room bass extension of 26Hz that few floorstanders at any price can approach. Available in Black Gloss, White Gloss, and Walnut, the R11 Meta is built for both dedicated listening rooms and high-performance home cinema systems.\u003c\/p\u003e\n\u003cp\u003eThe engineering heritage of the R11 Meta runs directly from KEF's flagship Reference Series. MAT, developed in collaboration with the Acoustic Research Centre at the University of Salford, uses a complex labyrinthine structure behind the tweeter to absorb 99% of unwanted rear-firing sound from the dome, eliminating the resonances and coloration that conventional tweeter designs cannot avoid. The 12th generation Uni-Q places the 25mm aluminium dome tweeter at the acoustic centre of the 125mm midrange cone, so the two drivers behave as a single point source across the crossover region. This widens the listening sweet spot and ensures the sound disperses evenly through the room rather than narrowing toward the primary listening axis. Four hybrid aluminium bass drivers, each with extended excursion capability, handle the low frequencies with the control and precision that a large cabinet demands. \u003c\/p\u003e\n\u003c!-- KEY FEATURES --\u003e\n\u003ch2\u003e\u003cspan style=\"color: #0f527f;\"\u003eKey Features\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFlagship R Series three-way bass reflex floorstander\u003c\/li\u003e\n\u003cli\u003e12th generation Uni-Q driver array with MAT\u003c\/li\u003e\n\u003cli\u003eMAT absorbs 99% of unwanted tweeter rear-radiation\u003c\/li\u003e\n\u003cli\u003eFour 165mm (6.5 in.) hybrid aluminium bass drivers\u003c\/li\u003e\n\u003cli\u003eFrequency range 30Hz to 50kHz; in-room bass to 26Hz\u003c\/li\u003e\n\u003cli\u003eMaximum output 113dB\u003c\/li\u003e\n\u003cli\u003eSensitivity 90dB (2.83V\/1m); nominal impedance 4 Ohm\u003c\/li\u003e\n\u003cli\u003eAmplifier requirements 15 to 300W\u003c\/li\u003e\n\u003cli\u003eCrossover at 330Hz and 2.5kHz\u003c\/li\u003e\n\u003cli\u003ePrecision-cut microfibre grille with 1,801 holes per driver\u003c\/li\u003e\n\u003cli\u003eCompatible with matching R Series home theatre models\u003c\/li\u003e\n\u003cli\u003eAvailable in Black Gloss, White Gloss, and Walnut\u003c\/li\u003e\n\u003cli\u003eEISA Loudspeaker Series 2023-2024; Hi-Fi News Outstanding Product 2024\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- WARRANTY --\u003e\n\u003ch2\u003e\u003cspan style=\"color: #0f527f;\"\u003eWarranty:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e5-year manufacturer's warranty\u003c\/p\u003e\n\u003c!-- WHY CONSIDER --\u003e\n\u003ch2\u003e\u003cspan style=\"color: #0f527f;\"\u003eWhy Consider the KEF R11 Meta\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003eThe R11 Meta is the right choice for listeners who want Reference-level acoustic technology at a price below the Reference Series itself. The combination of MAT and 12th generation Uni-Q removes two of the most persistent problems in high-quality speaker design: tweeter rear-radiation colouration and point-source dispersion. Four dedicated bass drivers give the cabinet authority and control at low frequencies that a single or dual woofer arrangement simply cannot match, and the 113dB maximum output means the speaker scales comfortably to large rooms and high listening levels without compression. For home cinema use, the full R Series lineup including matching centre and surround models ensures tonal consistency across the entire soundstage.\u003c\/p\u003e\n\u003ch3\u003eIdeal for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLarge dedicated listening rooms requiring full-range floorstanding performance\u003c\/li\u003e\n\u003cli\u003eAudiophiles wanting Reference Series technology at a more accessible price point\u003c\/li\u003e\n\u003cli\u003eHome cinema builds using matching R Series centre and surround speakers\u003c\/li\u003e\n\u003cli\u003eHigh-power amplifier pairings up to 300W in demanding acoustic spaces\u003c\/li\u003e\n\u003cli\u003eListeners who prioritise a wide, consistent sweet spot for multiple seating positions\u003c\/li\u003e\n\u003cli\u003eMusic and film in equal measure, across all genres and source formats\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- WHAT'S IN THE BOX --\u003e\n\u003ch2\u003e\u003cspan style=\"color: #0f527f;\"\u003eWhat's in the Box\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eKEF R11 Meta Floorstanding Speakers (pair)\u003c\/li\u003e\n\u003cli\u003eMicrofibre Grilles\u003c\/li\u003e\n\u003cli\u003ePlinth and Spike Accessories\u003c\/li\u003e\n\u003cli\u003ePort Bungs\u003c\/li\u003e\n\u003cli\u003eUser Manual and Warranty Information\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- SPECIFICATIONS --\u003e\n\u003ch2\u003e\u003cspan style=\"color: #0f527f;\"\u003eTechnical Specifications\u003c\/span\u003e\u003c\/h2\u003e\n\u003cstyle\u003e\n  .ph-spec-wrap { width: 100%;
