Product Description

  • The R Series’ dedicated low-frequency drivers have a two-part structure.

  • The R11 benefits from Constrained Layer Damping bracing originally developed for the multiple award-winning LS50, and a new internal bracing layout.

  • This combination brings the R closer to the internal structure of the Reference Series, and helps it deliver music as it is supposed to sound, without any unwanted extras.

  • R11 is the flagship of the new range. Boasting four 165mm (6 in.) hybrid aluminium bass drivers.

Product features

As any hi-fi enthusiast knows, there's no shortage of compelling speakers these days. But its beauty is only revealed when the sound isn't right. Luckily, the KEF R11 Floorstanding Speaker, the flagship of the venerable British brand's midsize R-series, packs smart tech for great sound into a beautiful package and comes at a lower price than you might expect. Sitting above the entry-level Q-series and below the reference series, the R-series was first launched in 2011 but is now a new version for 2018. With the latest model, the midrange is his Redesigned with Signature of R-series speaker.

 

Connect motor systems, cones and surrounds to Uni-Q coaxial arrays. Additionally, a new proprietary technique was developed to control the acoustics at the midrange junction of the tweeter and coaxial driver. According to KEF's tower speakers, these redesigns are designed to deliver a cleaner sound with less distortion and coloration. Judging by the time they spent in my listening room; I have to say that the R11 achieves these goals by a large margin.

A 3 Way speaker

The R-11s  pair 3-way bass reflex floor standing speakers that feature the same Uni-Q concentric array found in the Reference and Blade speakers: a 5-inch midrange driver and a 1-inch vented aluminium dome tweeter. I'm here. It also features a tangerine waveguide for improved high frequency dispersion. This latest version of his Uni-Q coaxial array is surrounded by a "shadow flare" trim ring that enhances the waveguide effect. 

Kef’s Crown

The unique Uni-Q Point Source, now in its twelfth version, has long been KEF's R 11 crown jewel, in this case literally the centrepiece. In this D'Appolito configuration, it's sandwiched between four 6.5-inch pieces of aluminium (paper and hybrid). Woofers, 2 above and 2 below Uni-Q. Uni-Q driver arrays are identified by name in small gray letters on the front panel. 

Most Demanded

Another way R-11 by KEF Speakers has reduced cabinet resonance is by returning it to an undesirable kind of colouring (acoustic kind). This is a rework of the cabinet's internal bracing layout, construction and damping system. For a purer, more neutral presentation. KEF manufactures both its own enclosures and drivers, resulting in greater design flexibility, innovation and ultimately more options for customers

Life-Giving

The R-11 is bi-wiring capable, but instead of jumpers between binding posts, it has a pair of knobs that rotate in either direction for bi-wiring or single-wiring. Bi-wiring he seemed to give the R 11 a boost - to spice it up a bit - but even with individual wires the speakers didn't feel "thin" in presentation

Known for simplicity

The KEF R11 loudspeaker is inherently designed to provide a kind of purity or neutrality to the sound, often revealing finer details to improve accuracy and realism. This is an attribute not routinely found in budget kef tower speakers like these. They also seem to work well with a wide variety of amplifiers and home theater setups. But even top-down coherence and scatter are believed to come to mind. It helped make the speakers sound more like the music itself instead of the speakers sounding like speakers and the drivers sounding like a box that shoots out sound waves

Magical

The R series speaker doesn't need a fancy room to work its magic. A pleasing presence - both acoustically and aesthetically - amazing realism and consistency between drivers, excellent value for money... R-11 has a lot to offer. They're popular and sell like the proverbial hotcake for good reason: get them while they're hot
