SOUND
Q50a Dolby Atmos-Enabled Surround Speaker
Q50a brings immersive Dolby Atmos height to Q Series home theatre systems. It is also easily mounted on the wall for a high-fidelity surround sound experience. Its Damped Tweeter Loading Tube produces a detailed and natural high frequency sound, and the styling means the Q50a will blend seamlessly into any interior.
"Sit anywhere" Uni-Q sound
The Uni-Q driver array places the tweeter in the centre of the midrange and bass cone, bringing the acoustic ideal of a single point source closer than ever. The result, enhanced by KEF's 'tangerine' waveguide over the tweeter, is a more accurate three-dimensional sound that's dispersed evenly throughout the room.
Tweaking the tweeter
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.
A word about drums and bass
The Q Series reproduces the nuances of bass instruments with ease. With a larger roll surround and new suspension KEF drivers produce cleaner bass at high volumes.
A new cone structure improves midrange clarity and an enhanced Auxiliary Bass Radiator (ABR) with a new surround and rear suspension enhances bass quality.
New system design
Putting the Uni-Q driver in its own sealed cabinet reduces the load on the cone and increases clarity and detail while delivering cleaner bass. Midrange clarity is enhanced by driver improvements that mean the DC blocking capacitor to be eliminated from the crossover, allowing a more natural roll-off between drivers.

| Q50A Dolby Atmos Speaker Module Review - Hi-Def Digest |
| "Here's the truth about Dolby Atmos branded/capable speakers: the overhead immersion is not only convincing, but we're also finding that they work well in imperfect environments (high or angled ceilings, etc.). Yes, bouncing sound off a ceiling isn't as precise as having in-ceiling speakers, but KEF's got you covered there too. The Q50a speakers include a built-in bracket for wall mounting, so you can hang these high on a wall for use as true Atmos overhead speakers. And they sound very good. Yes, they don't have the LF performance of the Q350 or Q150 bookshelf speakers, but with your AVR handling the crossovers and sending the LFE to your sub, you won't notice. ” |
