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 midrange 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
6.5" aluminum midrange driver.
- 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.
- 6.5" Aluminum Midrange Driver: The Uni-Q driver
array's 6.5" midrange driver
features an aluminum cone structure that has been
engineered reduce cone breakup and improve midrange performance. The
suspension allows more movement, better controlled excursion, and lower
distortion for accurate bass performance. As well as allowing the driver'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
Isolated Sealed Uni-Q Chamber: The
Uni-Q driver array is isolated in a closed chamber inside the speaker
cabinet to reduce distortions.
The closed box midrange cabinet design reduces the load on the Uni-Q
midrange cone, increasing clarity and detail while delivering cleaner,
Low-Frequency Woofer + Dual Auxiliary Bass Radiators (ABR): The
Uni-Q driver array is paired with a 6.5" low frequency woofer and dual
Auxiliary Bass Radiators (ABR). The same aluminum cone found in the Uni-Q's
midrange driver is also used in the bass woofer and dual ABRs for excellent
low-distortion midbass/bass performance. The woofer's
vented magnet assembly on a rigid metal chassis and 50mm voice coil offers
incredible power handling, while
the new rubber rear suspension of the ABRs provides greater excursion and a lower
tuning frequency so that the speaker can play deeper and louder. Both types of drivers
feature a large roll surround that allows a longer throw with less distortion at
high sound pressure levels.
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, an optional magnetically attached speaker grille (see
Accessories Tab) is 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.
Outrigger Feet w/ Spikes: The included outrigger feet and
spikes provide a larger, more stable footprint with greater stability. The
outrigger feet screw into the bottom of the speaker cabinet, while the spikes
screw into the bottom of the outrigger feet using the supplied hardware. Once
the outrigger feet and spikes are installed and the speaker is positioned, the
spikes can be adjusted from the top of the outrigger feet to make sure the
speaker is level with your floor.
- Dimensions w/ Outrigger Feet & Spikes: 12.875" (w) x
38.5" (h) x 12.375" (d)
- Dimensions w/ Outrigger Feet Only: 12.875" (w) x
37.1875" (h) x 12.375" (d)
- The spikes are designed for carpeted flooring. These spikes can
cause damage to hardwood, tile, laminate, and vinyl flooring (there are
no rubber feet included).
- The speaker should not be used without the outrigger feet installed
for stability and performance reasons.
- A pair of speakers should be positioned 6' to 10' apart.
They can be "toed-in" or angled inward toward the main listening area to improve
stereo imaging and soundstage.
