Model 205
In all the other Reference Series
models, the wide dispersion
Uni-Q/Hypertweeter pod is
faired into the cabinet itself.
As in the 207, advanced
computer modelling techniques
were used to optimise the
elliptical profile of the titanium
dome tweeter, whose output is
fine tuned to the Uni-Form
wave-guide. It makes the human
voice sound so real and so close
that you start looking around
for the source.
For the smoothest possible
response, much attention has
been paid to evening out flux
profiles. Both MF and HF coils
in the Uni-Q driver share a
compound twin neodymium
magnet assembly, and the two ultra-low distortion 200mm (8”) bass drivers have
balanced Faraday loops above and below the coil to ensure perfect symmetry.
Both long-throw bass drivers operate in parallel at low frequencies where
throw is critical, but the lower unit is rolled off early to allow the top LF
driver to dominate at the crossover to the midrange unit for the smoothest
possible integration.
The listening experience is spine-tingling, off-axis as well as on.Wherever you sit
in the room, there’s a near perfect illusion of presence - exactly what you want
for auditorium quality home theatre or to recapture that elusive live
concert ‘feel’.
Model 203
The 203 shares all this technical
virtuosity, only on a slightly
smaller scale.
Computer matched high order
four-way crossovers assure fluid
transitions between the five drivers.
The Hypertweeter and the new
Uni-Q coincident source array
together provide seamless mids and
highs while the two high-tech
165mm (6
1
⁄2”) LF drivers with KEF’s
high-tech motor systems and stiff,
lightweight reinforced diaphragms,
deliver deliciously open bass with
incredibly low distortion even at
high volume.
The curved section cabinets are
massively braced to eliminate box
colourations, and the open chassis
design of the drive units with vented
cones eliminates any trapped air
noise. Magnetically shielded like the rest of the range, the 203 combines
heavyweight muscle with intricate delicacy right across the frequency range.
Stereo imaging is superb, the detailing immaculate and the response so fluid you
could almost drink it.
Model 207
A true five-way design, the 207 is instantly
recognisable by the cast aluminium pod, which is
shaped to damp the internal sound field of KEF’s
new generation Uni-Q upper midrange driver.
Beneath the state-of-the-art elliptical profile
titanium Hypertweeter, a bonded Uni-Form
cone/surround provides the optimum waveguide
for the 25mm (1”) titanium dome HF unit leading
to exceptional vocal clarity.
The lower midrange driver is derived from the LF
unit, KEF’s lightweight neodymium magnet
assembly allowing it to be effectively decoupled
from the cabinet to improve imaging and
integration while minimising colouration.
Both long-throw 250mm (10”) bass drivers have
their own dedicated enclosures, tuned to different
frequencies for better performance in real rooms.
With a combined cone area equivalent to a single
375mm (15”) cone, they deliver staggering bass
extension of exceptional purity.
Incredibly lucid over an expansive sound stage,
with no discernible distortion - whatever sounds
you’re into, this is a supremely musical performer.
