The KEF R5 Meta<\/strong> floostanding speakers deliver an unparalleled audio experience incorporating the legendary British manufacturer\u2019s latest innovative speaker design and technology. The speaker\u2019s three-way bass reflex design houses a Uni-Q Driver Array featuring a 25mm tweeter, 125mm mid-range driver, and two 130mm bass drivers, resulting in rich and detailed sound across the entire frequency spectrum. KEF\u2019s<\/strong> Metamaterial Absorption Technology (MATTM) aids the driver design in providing accurate audio reproduction and further refines performance.<\/p>\n The R Series<\/strong> speakers feature a design that emphasizes the drivers and eliminates resonances or turbulence caused by the bass port. KEF<\/strong> utilised Computational Fluid Dynamics (CFD) to detect turbulence and resonant frequencies generated by the bass port, and then eliminated these issues with their innovative Flexible Wall Bass Port solution. Additionally, the R Series<\/strong>benefits from KEF\u2019s<\/strong> advanced cabinet design, including Constrained Layer Damping construction for stability and rigidity, and Shadow Flare technology that reduces diffraction from the cabinet.<\/p>\n Derived from\u00a0The Reference<\/strong>, Shadow Flare is an innovative way to cut harmful high frequency cabinet diffraction. It\u2019s a carefully profiled transition that extends the waveguide effect of Uni-Q\u00ae. The treble escapes naturally because the \u2018shadow region\u2019 stops it getting to the cabinet edges. The result is vastly improved fine detail.<\/p>\n A solid platform is imperative for great sound. The\u00a0R Series<\/strong>\u00a0benefits from constrained layer damping, a system that uses internal braces joined by a \u2018lossy\u2019 interface. This material converts unwanted vibration into heat, ensuring that the cabinet makes the only sound it needs to: the sound of silence.<\/p>\n R Series<\/strong>\u00a0bass drivers have a two-part structure with a shallow, concave, aluminium skin atop a paper cone. This stiffness, combined with the cone\u2019s unique geometry, achieves a piston-like movement for punch and speed. The drivers\u2019 magnet system creates a broad and uniform magnetic field which means more impressive and impactful bass.<\/p>\n We only want to hear the drivers, not the resonances or turbulence created by a bass port. The\u00a0R Series<\/strong> ports have innovative flexible walls. Using computational fluid dynamics, the flare and profile of each port is calculated to delay the onset of turbulence and the flexible port walls prevent resonances from coloring the midrange.<\/p>\nA Flare for Detail<\/h4>\n
