Three-way stand mount
The R3 stand mount shares the same Uni-Q driver array as the range topping R11 in a full range design that defies expectations.
A 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.
Priced as a PAIR of speakers.

TECHNOLOGY
THE SCIENCE OF SOUND
THE SCIENCE OF SOUND
Uni-Q
The evolution of KEF's Uni-Q driver reaches its 12th generation in the R Series. Using simulation and analysis tools KEF’s engineers have been able to dramatically reduce colouration by cutting resonance in the tiny gaps between Uni-Q’s elements. The result is purer and more precise sound with stronger imaging.
Shadow Flare
The Shadow Flare is an innovative way to cut harmful high frequency cabinet diffraction. It's a carefully profiled transition that extends the waveguide effect of Uni-Q. The treble escapes naturally because the ‘shadow region’ stops it getting to the cabinet edges. The result is vastly improved fine detail.
Low Frequency Drivers
R Series bass drivers have a two-part structure with a shallow concave aluminium skin atop a paper cone. Combine this stiffness with the cone’s unique geometry and you get near pistonic movement for punch and speed. KEF has also increased linearity in the magnet system which means more impressive and impactful bass.
Flexible Port Technology
When it comes to generating deep, articulate bass, port design is crucial. The R Series ports have innovative flexible walls. Using computational fluid dynamics the flare and profile of each port is calculated to delay the onset of turbulence and the flexible port walls prevent resonances from colouring the midrange.
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.
Microfibre Grilles
The R Series was created to sound its best with or without grilles. The microfibre grille design is a first for KEF and not only looks beautiful but has a negligible effect on performance. They continue the tone-on-tone approach to match the various cabinet finishes and the edges are burnished for a suede-like effect.

What a Revelation!!I have fallen in love with my music collection all over again! I am hearing things in songs I've heard a million times, that I've never heard before. I upgraded from Definitive Technology Monitor 65's which I loved for a long time. But the R3's blew them out of the water! The only downside is there isn't enough time in the day for me to listen as much as I want! Maybe I should schedule some vacation time!

Mind blowingThe speakers just disappear in the room and you are left with an out of this world soundstage! I can not put into words the sounds these speakers can produce. It is as if the instruments and artist are in my room! Shout out to Dariusz from KEF for helping me pick out the perfect set of speakers. I love my R3s!

| R3 Best Speakers 2019: Standmount |
| “Part of the company’s recently introduced premium R series, the R3s offer a large chunk of the pricier Reference 1’s engineering content and sonic performance at a fraction of the cost. And that's a winning combination. The R3s are brilliant all-rounders. They’re expertly sonically balanced and work well across a wide range of systems, but give them a top class feed and they will deliver a sound good enough to worry most standmounters below the two grand mark. This is one to buy with confidence.” |

| “The sound with KEF's R5-based system is no less detailed..., but it offers high-end performance in a more controlled, polite way with music and ample excitement for both surround music and movies.” |

| R3 Bookshelf Speaker Review |
| "We like the speaker’s clean appearance. But even here the decisions have been made on performance grounds. The shaped trim around the Uni-Q driver doesn’t just make the front panel look balanced by echoing the size of the larger bass driver; it also helps to reduce diffraction effects at the cabinet edges. That slim front looks smart and offers advantages in rigidity and dispersion." |
