Key Design Features

Uni-Q Driver Placement

The hallmark of KEF speakers, the Uni-Q driver array, positions the tweeter in the center of the midrange cone. This design ensures consistent sound dispersion, creating a wider sweet spot and an immersive listening experience.

The Uni-Q driver also reduces distortion by aligning the drivers’ acoustic centers, providing a coherent and unified sound image. This technology enhances on- and off-axis listening, making it ideal for diverse room configurations.

Redesigned Cabinet

The Q350 features an improved cabinet design with internal bracing that reduces unwanted vibrations and resonance. The relocated bass port minimizes turbulence and distortion at the back, enhancing low-frequency performance.

Additionally, the cabinet’s rigid construction helps in maintaining clarity and precision even at high volumes. The sleek edges and lack of visible screws further elevate its premium aesthetic.

Magnetic Grille

While the Q350 doesn’t come with a grille by default, KEF offers an optional magnetic grille for those who prefer to protect the drivers or achieve a different aesthetic. The grille’s minimalist design doesn’t compromise sound quality, ensuring the best auditory experience.
