KEF Q11 Meta: Timeless floorstanding speakers adept at producing high-quality sound

The KEF Q11 Meta model represents the top choice within its series, providing an outstandingly robust and immersive audio experience. These large floor-standing speakers excel in delivering high-fidelity sound in expansive living spaces, suitable for both stereo configurations and home theater setups. Despite their substantial size, the speakers boast a refined aesthetic due to their carefully considered proportions. Furthermore, the supports that extend beyond the base, equipped with relatively tall spikes, contribute to the speakers’ visual charm. This model is offered in a sophisticated matte finish, available in black, white, or walnut.

The KEF Q11 Meta speaker system features a state-of-the-art 12th generation Uni-Q driver. Significant design enhancements have been implemented to elevate sound quality further. The 19 mm aluminum dome tweeter is mounted on a Tangerine waveguide, which optimizes its directivity and minimizes phase distortions. Additionally, a sound-absorbing MAT element is positioned at the rear of the high-frequency driver, representing a key advancement in the latest Uni-Q technology. This MAT element is designed to be thin, preserving the compactness of the driver while effectively dissipating sound waves emanating from the back of the tweeter dome. As a result, the speaker delivers a clear and detailed high-frequency sound.

The 10 cm midrange speaker in the Uni-Q features a diffuser designed with longitudinal stiffening ribs to effectively reduce resonances. Its driver frame is angled to ensure a more consistent sound wave distribution, minimizing distortion that may arise from reflections off the front panel. In the KEF Q11 Meta, the low-frequency speaker is fitted with an aluminum diffuser that incorporates specialized ribs to enhance rigidity. Additionally, the tweeter is constructed with an aluminum diaphragm and includes acoustic dividers shaped like petals. Both speakers share a common chassis, and their magnetic systems are meticulously aligned for optimal performance.

There are three 165 mm bass speakers that appear identical at first glance. However, the true bass speaker is situated in the center, while the passive ABR bass radiators are positioned above and below it. This acoustic configuration offers benefits in bass performance and depth when compared to a conventional bass reflex design. Nevertheless, the complexity involved in its implementation means that this approach is seldom found in budget-friendly audio systems. Each speaker features a tidy edging.

To avoid vibrations in the speaker body that could alter the sound quality at high volumes, internal braces are utilized for reinforcement. Additionally, partitions are incorporated to separate the upper section housing the Uni-Q driver and to establish a dedicated working volume for the low-frequency drivers. The KEF Q11 Meta features a crossover filter constructed from premium components. A carefully designed crossover configuration minimizes frequency and phase distortion, resulting in a sound that is both balanced and musical.
