The R8a is a flexible solution for anybody wanting to bring an all-immersive movie experience to their home. With the integrated wall mount feature, R8a can serve as a surround or rear speaker. Alternatively, if placed upon another speaker, R8a will bounce sound off the ceiling, bringing Dolby Atmos to the home without the need of custom installation. Equipped with a 130mm (5.25in.) Uni-Q array with a 25mm (1 in.) tweeter, every detail is described, steered around the listening space as the director intended.
Placing the tweeter in the acoustic centre of the midrange cone brings the acoustic ideal of a single point source closer to realisation. The new R Series benefits from a new 12th generation of the legendary Uni-Q which has been extensively designed using KEF’s in-house simulation and analysis tools. KEF’s engineers have been able to dramatically reduce colouration through reducing resonance in the minute gaps between Uni-Q’s separate elements. The resulting sound is purer, more precise and makes stereo imaging far more believable.
Low Frequency Drivers
Bass is the very foundation of music; everything is built upon it and maximising bass performance is a vital building block towards pristine sound. R Series bass drivers are built using a two-part structure, where a shallow concave aluminium skin sits atop a paper cone. This great stiffness, combined with the cone’s unique geometry, delivers pure piston like movement to deliver punch and speed. To accurately control this mighty driver, KEF has also completely redesigned its magnet system to create a more even magnetic field. The overall result is more impressive and impactful.
Flexible Port Technology
When it comes to generating deep, articulate bass, port design is crucial. The ports in R Series feature innovative flexible walls. Using computational fluid dynamics, the flare and profile of each port is calculated to delay the onset of turbulence, while the flexible port walls prevent longitudinal resonances from colouring the midrange.
