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 to 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.

Centered Drivers: To optimize the high resolution purity of the Q Series bookshelf speaker, the Uni-Q driver array is positioned to the center of the cabinet to reduce unwanted internal resonance and adding refinement to sonic clarity and detail. Expect to hear clear highs, smooth midrange and clean bass with minimum distortion at any volume level.

Computational Fluid Dynamics (CFD) Port Design: Featuring a Computational Fluid Dynamics (CFD) port design with the port positioned to the rear of the speaker, clarity is improved by reducing the audibility of the midrange leakage through the port. The port is also flared to minimize turbulence at high levels and reduce port noise with less low frequency compression.

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, optional magnetically attached speaker grilles (see Accessories Tab) are available and sold separately.

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 bookshelf speaker can simply be placed on a stand, table-top, shelf, or other flat-surface. The included self-adhesive rubber feet protect your furniture and add approximately 0.1875" to the overall height of the speaker. A pair of speakers should be positioned 6' to 10' apart and placed between 18" to 24" off the floor. They should be positioned at least 9" from the back wall due to their rear-firing port and 39" from side walls. The speakers can be "toed-in" or angled inward toward the main listening area to improve stereo imaging and soundstage.

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), two center channel speakers (Q650C/Q250C), 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.
