KEF R5 Floor Standing Speaker (Pair, Walnut)
- 125mm midrange driver
- 25mm aluminium dome tweeter
- 130mm bass drivers
- 1025 x 175 x 343.5mm with terminal
The svelte styling of KEF R5 Floor Standing Speaker (Pair, Walnut) contains the same Uni-Q as its bigger brothers, with a 125mm (5in.) midrange driver and 25mm (1 in.) aluminium dome tweeter producing incredible levels of detail. The slightly smaller 130mm (5.25 in) bass drivers still produce exceptionally clean bass whether placed in a smaller room or as surround speakers as part of the ultimate home theatre system.
Uni-Q Driver Array
The Uni-Q driver array acts as a single point source, providing pristine sound across a wider area. The R Series benefits from a new incarnation of this driver array, with advantages over its predecessors that include a new midrange motor system that drastically reduces distortion.
the Shadow Flare reduces harmful cabinet diffraction, it is a precision-designed surface that extends the waveguide effect of Uni-Q.
Low Frequency Drivers
The R Series’ dedicated low-frequency drivers have a two-part structure, where a shallow concave aluminium skin sits atop a paper cone. The new drivers also have a completely redesigned magnet system that creates a more even magnetic field, and a design of spider that reduces harmonic distortion for a cleaner, more precise sound.
The R Series benefits from Constrained Layer Damping bracing originally developed for the multiple award-winning LS50, and a new internal bracing layout.
Flexible Port Technology
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.
