Overview

Our take on the KEF Q50a

Putting together a KEF Q Series home theater system? Then you may want to consider a pair (or two) of KEF's Q50a surround speakers. This crafty speaker fires upward, bouncing sound effects off of your ceiling to add a layer of sound above you — perfect for a Dolby Atmos® or DTS:X™ system. 

Exciting sound effects

Putting together a KEF Q Series home theater system? Then you may want to consider a pair (or two) of KEF's Q50a surround speakers. This crafty speaker fires upward, bouncing sound effects off of your ceiling to add a layer of sound above you — perfect for a Dolby Atmos® or DTS:X™ system. 

You can also wall-mount a pair as traditional side or rear surround speakers. In this orientation they fire forward, providing lifelike sound effects in a traditional surround sound speaker arrangement.

KEF Q50a surround speaker

Place the Q50a on top of a KEF Q Series floor-standing speaker to reflect sound effects off of your ceiling.

Immersive sound thanks to Uni-Q® technology

KEF's patented Uni-Q technology places this speaker's 1" tweeter in the acoustic center of the 5-1/4" woofer. This concentric design allows sounds to originate from a single point source, making the "sweet spot" (the ideal listening position) much larger.

Here at Crutchfield, we've had the pleasure of hearing Uni-Q technology in person many times, with KEF's super-popular, award-winning LS50 speakers. Sit wherever you like — you'll enjoy detailed, accurate three-dimensional sound throughout your room.

Note: this speaker is sold individually, so you'll want to pick up two for your system.

Features

Dolby Atmos-Enabled Surround Speaker: Bring immersive, cinematically vertical Dolby Atmos sound or surround sound optimized for KEF's Q Series loudspeakers home with the Q50a Dolby Atmos-enabled surround speaker. Equipped with the latest Uni-Q driver array (consisting of a 1" tweeter and 5.25" mid-bass woofer) and other advanced technologies, dynamics is excellent while response is accurate and clean. KEF'S Q50a Dolby Atmos-enabled speaker sits above your existing floorstanding or bookshelf home theater speakers. Knowing how the brain perceives sound, KEF engineers have perfected a way of beaming the sound upwards from the Q50a so that it's reflected by the ceiling to replicate the vertical dimension in Dolby Atmos recordings.

Note: 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.

Uni-Q Driver Array: At the heart of the Q Series loudspeaker is the Uni-Q driver array. This signature innovation by KEF places the tweeter in the acoustic center of the mid-bass cone, with both drivers acting as a single point source. The result is a more detailed, accurate three-dimensional sound image, which is dispersed more evenly throughout the room than is possible with any conventional speaker. The Uni-Q driver array is made up of a 1" aluminum dome tweeter and a 5.25" aluminum mid-bass woofer.

  • 1" Aluminum Dome Tweeter: At the center of the Uni-Q driver array is a 1" aluminum dome tweeter that utilizes KEF's "tangerine" waveguide over the tweeter dome for ultra-wide dispersion. Further enhancements to the 1" aluminum dome tweeter is a damped loading tube and a cone-neck de-coupler. The damped tweeter loading tube reduces any harshness in the lower treble frequencies by gently terminating the sound produced from the rear. The cone-neck de-coupler reduces output in the cone breakup region to improve high frequency performance.
  • 5.25" Aluminum Mid-Bass Woofer: The 5.25" mid-bass woofer features an aluminum cone structure that has been engineered reduce cone breakup and improve midrange performance. The woofer's optimized suspension allows more movement, better controlled excursion, and lower distortion for accurate bass performance. As well as allowing the woofer's cone its full extension, KEF's ingenious Z-flex surround guides the sound from the tweeter across the surround without any disturbance or secondary radiation.

Sleek Cabinet Design: The sculpted Q Series finish epitomizes KEF's approach with seamless, sleek cabinets unblemished by visible fittings and joints. Q Series speakers are coated with a fine satin finish with matching driver colors. If you wish to conceal the drivers, magnetically attached speaker grilles are included.

Gold-Plated Binding Post Terminals: On the rear of the speaker cabinet is a pair of heavy-duty, gold-plated binding post terminals that will accept bare wire (up to 10AWG), pin-connectors, spade-lugs, and banana plugs (single only). Plastic inserts must be removed from the binding posts to use banana plugs.

Mounting & Placement Options: The KEF Q50a loudspeaker can be placed on top of a loudspeaker for Dolby Atmos applications, or can be wall-mounted for surround sound applications.

  • Top-Mount: The Q50a loudspeaker has been expertly tuned by KEF 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 floorstanding and bookshelf speakers. The included rubber feet should be used when placing the Q50a on top of another loudspeaker (the rubber feet add approximately 0.1875" to the overall height of the speaker). Make sure the top of your loudspeaker measures 7.125" (w) x 10.25" (d).
  • Wall-Mount: The Q50a can also be easily mounted on the wall using the integrated keyhole slots on back of the speaker (mounting screws not included), creating a high-fidelity home surround sound experience that melds seamlessly with the KEF's Q Series speakers.
Note: A pair of KEF Q50a loudspeakers should be spaced at least 6' to 10 apart, placed 9" or more from the ceiling, and positioned 39" or more from side walls.

Q Series: Q Series speakers by KEF deliver natural, accurate, high-resolution sound. First introduced in 1991, the multiple award-winning Q Series has long delighted music lovers and audiophiles with outstanding sound quality and innovative design. The Q Series, now in its 8th iteration, brings high resolution sound with more depth and more clarity. The Q Series consists of three floorstanding speakers (Q550/Q750/Q950), two bookshelf speakers (Q150/Q350), center channel speaker (Q650C), and Dolby Atmos speaker (Q50A) - all sold separately.

Optional Powered Subwoofer: A KEF Kube series powered subwoofer (sold separately) is the perfect addition to the Q Series loudspeakers.
