KEF Q11 Meta
3-way floorstanding speaker with Uni-Q driver

The Q11 Meta, the flagship among the floorstanding models in the Q series, is designed for impressive performance in larger rooms and home theaters. Equipped with 12th generation Uni-Q® drivers featuring MAT™ technology and three 6.5" hybrid aluminum bass drivers, it delivers music and movie sound with refined detail, powerful bass, and uncompromising depth.

Revolutionary sound absorption with MAT

The core innovation of the Q series is the integrated Metamaterial Absorption Technology (MAT)1, a revolutionary breakthrough that allows the latest 12th generation Uni-Q drivers to play with unprecedented precision and clarity.
MAT is a highly complex, labyrinth-like structure where each branched channel efficiently absorbs a specific frequency. Combined, the channels act like an acoustic black hole, absorbing 99% of unwanted sound coming from the rear of the tweeter, eliminating resulting distortions, and providing a purer, more natural acoustic performance.

 

Deep and clear bass

The Q series features a new bass driver design4—a hybrid structure with a flat, concave aluminum skin on a paper cone—that provides stiffness for piston-like movement, delivering more bass pressure and speed. Combined with a 3D
FEA-optimized surround geometry, this significantly improves linearity at higher excursions. The result is precise and agile bass control even at high output.
Additionally, the conical bass reflex port, modeled using computational fluid dynamics, reduces turbulence and unwanted airflow noise (the so-called "chuffing"). This allows the bass reflex speakers to produce cleaner and more controlled bass.

 

Crossover improved through 1000 measurements

A crucial component of the Q series is the more sensitive crossover, ensuring seamless integration of all speaker components. To achieve this, our engineers conducted over 1000 specific measurements for each speaker model in our anechoic chamber in Maidstone, UK, using a specialized reference microphone setup. Thanks to these extensive on- and off-axis measurements, our team thoroughly understood the acoustic interactions of each model and achieved a precise crossover design through advanced simulations and forward-looking prototyping. This meticulous process was first applied during the development of the LS50 Meta and has been further refined for the latest Blade, Reference, and R series. This ensures a precise signal path and optimizations for the best possible performance for every speaker model.

 

Shadow Flare for enhanced transparency

Shadow Flare4, derived from the flagship models, represents another improvement for the evolved Q series. This design reduces unwanted reflections at the corners of the speaker cabinets, allowing the 12th generation Uni-Q drivers with MAT to reach their full potential. Shadow Flare is a precisely engineered surface that enhances the sound radiation of the Uni-Q drivers. This means the tweeter no longer has a "line of sight" to the cabinet edges. This creates a "shadow zone" where the potential for reflections is highest, reducing their acoustic impact to a negligible level. The improved clarity and reproduction of fine details make listening a truly immersive experience. Subtle nuances like the delicate brush of a jazz brush on a cymbal or the complex overtones of a piano are rendered much more clearly with the Q series.
