Kef R3 Standmount Speakers

Stock Availability : Only 1 left in stock.

The KEF R3 stand mount shares the same Uni-Q driver array as the range topping R11 in a full range true 3-way speaker the R3 has a powerful 165mm (6.5 in.) bass driver and a 125mm (5 in.) midrange driver with 25mm (1 in.) aluminium dome tweeter Uni-Q array that pushes performance to new extremes…

For starters, Uni-Q’s midrange motor system has been completely redesigned using KEF’s in-house simulation and analysis tools as well as decades of experience. The motor is responsible for converting the audio signal from an electrical voltage to a mechanical force. Ideally it does this without any loss and without introducing any distortion. For a midrange driver, significant distortion can be generated due to modulation of the voice coil inductance. The motor in the new R Series has a shaped and undercut pole, and symmetrical aluminium demodulation rings, which combine to significantly reduce the inductance in the lower midrange so there is less variation as the voice coil moves…

To maximise bass performance in the new R Series, the dedicated low-frequency drivers are built using a two-part structure, where a shallow concave aluminium skin sits atop a paper cone. This stiffness combined with the cone’s unique geometry reduces additional resonances and delivers the pistonic movement that makes these drivers time so well…

The drivers also benefit from a completely redesigned magnet system that creates a more even magnetic field, and a design of suspension that reduces harmonic distortion for a cleaner, more precise sound.

The result is tight, agile bass that digs out all the soul and punch available in the low end.

All the cabinets in the new R Series benefit from Constrained Layer Damping bracing. Originally developed for the multiple award-winning LS50, this system utilises internal braces joined to the panels by a lossy interface rather than being adhered to it rigidly. This approach is highly effective at dissipating unwanted vibrations.

The internal bracing layout works alongside Constrained Layer Damping to create an incredibly inert platform from which the drive units can work their magic, enabling the R Series to deliver music as it is supposed to sound, without any unwanted extras
