The KEF R11 Meta Floor standing speakers are an upgrade to their predecessors, featuring a new Meta technology for improved midrange detail and a wider soundstage. This makes them perfect for truly immersive, high fidelity audio experiences and equally at home in a home cinema set-up. The R11 Meta speakers build on the R5 Meta to deliver a bigger sound with a fuller bass response. The R7 Meta also suit a larger room size than the smaller R5 in the range.

KEF R11 Meta Floor Standing Speakers

The KEF R11 meta loudspeakers are a Tall but slim three-way floor standing speaker.
The R7 Meta, is as powerful as it is flexible. Its 12th generation Uni-Q® driver array with MAT™ ensures a crystal-clear performance with music and movies alike, while its four 6.5” hybrid aluminium bass drivers deliver awesome, tight, accurate, dynamic bass.

Developed for KEF’s flagship The Reference, a suite of the latest technologies has now made its way into the new generation of the R Series. Whether in stereo for music or in a home theatre set up the R Series makes exceptional acoustic performance more accessible. Now with the ground-breaking Metamaterial Absorption Technology, the R Series reveals exquisite detail and incredible insight: truly an experience to savour.

Another key improvement here is the inclusion of the aforementioned MAT (Metamaterial Absorption Technology). After its debut and success with the Award-winning LS50 Meta speakers (which sit below the R Series), it was inevitable that this revamped range would incorporate this MAT technology. MAT is a puck-sized, maze-like plastic structure that sits behind the tweeter and absorbs the unwanted backward radiation from the tweeter into the cabinet. KEF claims that MAT (made up of 30 tubes, each designed to absorb a particular high frequency) absorbs 99 per cent of these distorting sound waves. The result? Less distortion, clearer highs. 

The R11 Meta is the top of the range tower speaker in the new R Meta series. The R11's up the game from two 6.5" woofers in each speaker to four - these changes ensure lower distortion across a wider frequency range as well as the ability to play at a higher SPL.

The KEF R11 meta speakers deliver an open midrange that presents a very wide and detailed soundstage due to the UniQ driver - now with the four bass drivers the bottom end of the R11 speakers demonstrate how room filling great music and theatre can sound.
