The KEF R11 floorstanding Loudspeaker, the largest loudspeaker in the range, features four 165mm (6½ inch) diameter bass drivers, enabling a enough sound level output to drive large rooms without distress. The large cabinet affords the most extended bass response.

The new KEF R Series has been completely re-engineered from the ground up, with 1,043 changes undertaken during the design process, to further improve upon the performance, build and finish of original R Series speaker range. The new range features a 12th generation Uni-Q drive unit array and increased output, enabling the listener to enjoy increased volume levels, when partnered with a suitably equipped amplifier.

Our team attended the official U.K. launch of the new KEF R Series in September 2018, and are of the opinion that the new R Series models are a statement product in their own right. There are a few trickle down technology improvements taken from the Reference Series that have been applied to the KEF R11, enabling the performance bar to be raised.

Performance aside, the new models have greater visual appeal, with classy upgrades applied to the creation of the beautifully engineered speaker grill, outriggers to improve the stability, and trim rings that surround the speaker drive units. Consumer research was undertaken during the design process, forming the creation of the new KEF R Series. In fact, the only thing to remain the same is the name.

Decades of experience and unbridled passion for music come together in the new KEF R11. It combines innovations drawn from the Reference Series with new bespoke technologies to ensure the new R Series delivers more detail, deeper insight and greater excitement. Every element of the new KEF R Series has been precisely engineered to recreate the exhilaration of hearing music for the first time.
