KEF Q7 Meta (Walnut)

KEF Q7 Meta
3-way floorstanding speaker with Uni-Q driver

The Q7 Meta is a floorstanding speaker designed for impressive bass and acoustic clarity. Featuring 12th generation Uni-Q® drivers with MAT™ technology, it delivers a detailed and lifelike performance. Combined with two 16.5 cm hybrid aluminum bass drivers, the Q7 Meta offers an immersive and captivating music and movie experience.

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 perform with unprecedented precision and clarity.
MAT is a highly complex, labyrinthine structure where each branched channel efficiently absorbs a specific frequency. Together, the channels act like an acoustic black hole, absorbing 99% of unwanted sound coming from the back 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 over a paper cone—that provides stiffness to achieve piston-like motion for greater bass impact 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 levels.
Additionally, the conical bass reflex port, modeled using computational fluid dynamics, reduces turbulence and minimizes unwanted airflow noise (known as "chuffing"). This allows the ported speakers to produce cleaner and more controlled bass.

 

Crossover improved through 1000 measurements

A critical 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, with advanced simulations and cutting-edge prototyping, achieved a precise crossover design. 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 flagship models, represents another advancement 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 improves the sound radiation of the Uni-Q drivers. This means the tweeter no longer has a "line of sight" to the cabinet edges. A "shadow zone" is created 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 captivating 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.
