Description
Q50a Dolby Atmos-Enabled Surround Speaker
Q50a is expertly tuned by KEF Q50A acoustic engineers to bring extraordinarily immersive, cinematically vertical Dolby Atmos sound into the home using precision ceiling reflection when placed on top of Q Series speakers. It is also easily mounted on the wall using dedicated keyholes, creating a high-fidelity home surround sound experience that melds seamlessly with the newest Q Series speakers. Its Damped Tweeter Loading Tube produces a detailed and natural high frequency sound. Part of the Q Series family, Q50a’s visual design shares elements with other Q Series speakers, allowing it to blend seamlessly into contemporary interior design.
“Sit anywhere” Uni-Q Sound
At the heart of the evolved Q Series is the Uni-Q driver array. KEF’s signature innovation places the tweeter in the acoustic center of the midrange cone, bringing the acoustic ideal of a single point source closer than ever to realisation. The result is a more detailed, more accurate three-dimensional sound image, which is dispersed more evenly throughout the room than is possible with a conventional speaker. Uni-Q’s ultra-wide dispersion is further enhanced by KEF’s ‘tangerine’ waveguide over the tweeter dome..
Uni-Q sound taken to the next level
With the addition of the damped tweeter loading tube providing a gentle termination of sound produced from the back of the tweeter, lower treble performance is improved dramatically and a new low-distortion inductor on the crossover provides cleaner bass.
What is Dolby Atmos?
In real life, sound comes from all around. But conventional surround systems only allocate it horizontally – left, right, ahead and behind. What makes Dolby Atmos so staggeringly realistic is that the movement of every sound in the scene is reproduced in all three dimensions, including vertically. This creates a true 3D acoustic image of precisely located individual sounds that move in relation to you as if you were actually there. The effect is uncanny. Exhilarating. Sometimes scary, sometimes hilarious; always engrossing.
How Does It Work?
How does it work?Dolby Atmos is infinitely more flexible and adaptable than channel-based home theatre. When a Dolby Atmos stream is fed to a Dolby Atmos compatible A/V receiver, the receiver will render the object-based audio to your home theatre’s unique speaker configuration to precisely recreate the sound the filmmakers intended. Dolby Atmos has the ability to adapt to diverse speaker setup. You can enjoy the full effect with just seven KEF Q50A speakers.
