KEF R3 Bookshelf Loudspeakers redefines standmount performance. No surprise, as it shares the same drivers as the range-topping R11. A true three-way speaker, the 165mm (6.5 in.) bass driver pushes bass performance to new extremes. The 125mm (5 in.) midrange driver and 25mm (1 in.) aluminium dome tweeter creates a Uni-Q array that defies the expectations from the most compact main speaker in the range.

Key Features

  • Uni-Q
    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.

  • Shadow Flare
    Shadow Flare is an innovative method of reducing harmful cabinet diffraction for delicate high-frequencies. A carefully profiled transition surface which extends the waveguide effect of Uni-Q.

  • Low-Frequency Drivers
    R Series bass drivers are built using a two-part structure, where a shallow concave aluminium skin sits atop a paper cone.

  • Cabinet Bracing
    The new R Series benefits from Constrained layer damping.

  • 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.
