Great loudspeakers disappear, leaving just the music. LS50 Meta is such a loudspeaker. The incredibly immersive sound means you lose yourself in your favourite music. Savouring every nuance as layer upon layer of instrumentation is delivered with exceptional acoustic accuracy anywhere in the room.
Metamaterial Absorption Technology
A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology (MAT) is a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.
Every spot is the sweet spot
12th generation Uni-Q with MAT
Using advanced simulation and analysis tools, our engineers have developed the 12th generation Uni-Q with MAT. This new driver array delivers reduced colouration, less distortion and a sound that is more transparent and life-like than previously possible, all dispersed evenly throughout the room.
Curved for performance
LS50 Meta’s low-diffraction, curved baffle is precision modelled around the Uni-Q driver array. Its smooth curved surfaces help radiate sound out across the baffle without any interference from hard edges, which cause diffraction. The result is cleaner, more precise sound.
Braced for action
LS50 Meta’s baffle is engineered from an injection-moulded Dough Moulding Compound (DMC), while inside the cabinet cross bracing and Constrained Layer Damping (CLD) combine to deaden internal vibrations. The result of such meticulous attention to detail is the lowest colouration of any speaker in its class.
Using Computational Fluid Dynamics (CFD), the port flare and profile of LS50 Meta’s patented off-set port is calculated to delay the onset of turbulence, and the flexible port walls prevent resonances from colouring the midrange. This leads to improved clarity, with exceptional depth and detail.
