KEF Q4 Meta (Satin Black)

KEF Q4 Meta
2-way wall speaker with Uni-Q driver

The sleek and elegant Q4 Meta is an incredibly versatile wall speaker that can be used as an LCR speaker (left, center, right) or as a surround speaker. Featuring 13 cm Uni-Q drivers of the 12th generation with MAT™, the Q4 Meta delivers a spacious and immersive soundstage without taking up valuable floor space.

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, labyrinth-like structure where each branched channel efficiently absorbs a specific frequency. Combined, these channels act like an acoustic black hole, absorbing 99% of unwanted sound emanating from the back of the tweeter, eliminating resulting distortions and delivering a purer, more natural acoustic performance.

 

Improved crossover refined 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 using a specialized reference microphone setup in our anechoic chamber in Maidstone, UK. Thanks to these extensive on- and off-axis measurements, our team gained a thorough understanding of each model’s acoustic interactions and, through advanced simulations and pioneering prototyping, achieved a precise crossover design. This meticulous process was first employed 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 our 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. 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 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.
