Uni-Q Driver Array
Putting the tweeter in the aural center of the midrange cone brings the acoustic model of a single-point source nearer to comprehension. The new R Series profits from a new 12th generation Uni-Q developed through extensively using KEF’s in-house simulation and investigation tools. KEF’s engineers drastically reduced coloration by lowering resonance in the microscopic gaps between Uni-Q’s distinct components. The result is a cleaner, more precise sound that makes stereo imaging far more authentic.
Shadow Flare
Derived from the Reference Series, Shadow Flare is an advanced method of decreasing harmful cabinet deflection for subtle high-frequencies. Shadow Flare is a wisely profiled conversion surface that prolongs the waveguide result of Uni-Q. The tweeter no longer has a line of sight of the cabinet edges, creating a ‘shadow region’ at the highest potential for diffraction. The performance is vastly improved in detail, specifically the subtle nuances of percussive sounds.
Cabinet Bracing
A solid platform is imperative for great sound. The new R Series benefits from Constrained layer damping. This system utilises internal braces joined by a ‘lossy’ interface and is highly effective at dissipating unwanted vibrations that would otherwise artificially change the sound and music.
Low-Frequency Drivers
Bass is the very foundation of music; everything is built upon it and maximizing bass performance is a vital building block toward a pristine sound. R Series bass drivers are built using a two-part structure, where a shallow concave aluminum 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
Port design is critical to producing deep, articulate bass so the port hosts inventive flexible walls. Using computational molten dynamics, the flare and silhouette of each port is intended to delay the arrival of turbulence, while the flexible walls prevent longitudinal interference from colouring the midrange.
