KEF Q650c

Acoustic Technology Uni-Q
At the heart of the ultimate Q Series version is the Uni-Q speaker. This proprietary technology puts the tweeter at the acoustic center of the medium / low cone, making it possible to achieve the acoustic ideal of the single source. The result is a more detailed and precise three-dimensional sound image that is more uniformly dispersed throughout the room such as no other conventional enclosure can accommodate. Ultra-wide dispersion Uni-Q technology is enhanced by the guide KEF waves placed around the dome of the tweeter.

Innovative design
To optimize the high-resolution purity of the Q-series speakers, the Uni-Q speaker is repositioned in the center of the speaker to reduce unwanted internal resonance and further fine-tune sound clarity and detail. The addition of the cushioned tweeter charging tube delivers smooth and complete damping of the tweeter's rear sound, treble performance is dramatically improved and a new low-distortion coil on the filter delivers flawless bass.

Events designed by CFD (fluid dynamics)
Thanks to a CFD (fluid dynamics) vent and repositioned at the rear of the enclosure, avoiding disturbance due to the medium frequencies present at the output of the event, you will obtain a lighter sound.
