Hello and good day!  We are AudioVision SF, a brick-and-mortar
hifi store in the heart of San Francisco for 20 years!  We have had the pleasure of selling fine home
audio and video goods for decades, and have a really great offer for you
today!  All of our floor sample demo
items come will original boxes, materials, and the best news – a full
manufacturer’s warranty!  Also, if they
are to be shipped, we shall pay for shipping!

 

We are selling our demo Reference 3
floorstanding loudspeakers from KEF at a great reduction, especially great
since they are super mint and have been very very well taken care of!  They come in gloss Rosewood, and are
absolutely stunning.  KEF rose to fame
with their innovative single-point source Uni-Q driver, and have been making
some of the best loudspeakers in the world ever since!  Their Uni-Q driver means the tweeter and
mid-ranger driver are perfectly in phase and time-aligned, since they occupy
the same location, and thus deliver exceptional soundstaging and transparency.

 

The Reference 3’s are the smaller of the two
floorstanders in KEF’s reference line, and are perfect for mid-sized to larger
rooms.  With unparalleled detail and
resolution in the upper frequency range, with bass that drops all the way down
to 43 Hz!!  With a dynamic, forward, and
expressive personality, it’s hard to imagine these not being the perfect fit if
you are in the market for full-range loudspeakers in this price range.  And on that note, these were originally
$14,000, so an even better buy at $10,399! 

 

From KEF:

 

“Uni-Q Driver Array

At the heart of The Reference is a stunning
new iteration of KEF’s landmark innovation: the Uni-Q point source MF/HF driver
array. With a state-of-the-art 25mm (1in.) vented aluminium dome tweeter at the
exact acoustic center of a highly sophisticated 125mm (5in.) mid range driver,
both act as a single source that floods the listening space evenly with a
flawless natural sound field, no matter where you sit. Capturing all the
nuances of the human voice, whether whispered, spoken or sung, it sounds as if
the person were right there with you in the room. All the jaw-dropping
performance and innovative engineering pioneered for the critically acclaimed
LS50 studio monitor, and then some. Reference 3 pairs KEF’s latest 125mm (5
inch) MF/HF Uni-Q driver array with two sensational new 165mm (6.5 inch) alloy
cone bass driver to create a compellingly realistic and completely immersive
sound stage. The Reference 3's Uni-Q cast an inherently wide, even dispersion
that also also makes it a tremendous rear channel speaker in a home theater
system that effortlessly reveals all the subtleties encoded in modern
soundtracks.

 

Bass Driver

Clean, rich and articulate bass grounds your
enjoyment of stereo or multi-channel sound, and like everything else about The
Reference, KEF’s new 165mm (6.5 inch) LF driver is in a class apart. With a
massive vented magnet assembly and a large aluminium wire voice coil driving an
exceptionally light, stiff and strong alloy cone, the dynamics and power
handling are superb. Played loud or soft, in delicate passages or for full-on
bass effects, the combination of advanced materials and clever engineering
delivers deeply rewarding lows that blend seamlessly with Uni-Q’s immaculate
mid range and treble response. The Reference 3 features two of these immensely
powerful bass drivers.

 

Cabinet Design

The Reference drivers are set in a smooth,
strikingly distinctive front baffle engineered to eliminate response anomalies
caused by diffraction. Made from an exceptionally strong laminated
aluminium/resin composite and secured via high-loss pads and high tensile
bolts, it adds tremendous rigidity to the inert cabinet. Finished by hand in
pair-matched wood veneers to complement the composite front baffle, the shape
and bracing geometry of the cabinets are computer-optimized to minimize
secondary radiation from the cabinet walls and distortion from standing waves.
With constrained layer damping to absorb residual vibrations, they’re
engineered to eliminate any panel resonance, stray reflections or box
coloration effects that would compromise the purity of the sound.

 

Flexible Port Technology

The flexible port technology pioneered for the
multi-award winning LS50 is used to reduce mid range port resonance, with the
flare and profile of each port calculated by computational fluid dynamics to
avoid turbulent air noise that might color the sound.

The Reference has innovative adjustable ports
for fine-tuning the bass output to your personal taste and the room
characteristics providing the ultimate flexibility for any room.

 

Crossover Design

KEF engineers computer-modeled the ideal
crossover networks before exhaustively auditioning every high grade component,
individually and together, to select those with the lowest distortion and the
smoothest response. Perfectionism takes time, but the difference is plain to hear.
Nothing is overlooked - Reference crossovers are even mounted on separate
boards and decoupled from the cabinet walls to minimize vibration and
crosstalk.”
