KEF Audio KEF Coda7 - Manual (Page 4)

Because the centre channel carries so much of the audio infor-
mation in a home theatre set-up, KEF
engineers took particular
care perfecting the Coda
80. A two-way bass reflex
like the rest of the range, it
features the same high per-
formance 25mm (1”) metal
dome tweeter for superbly
realistic reproduction of vocals -
whether whispered, spoken, shouted or sung.
Flanking the tweeter and reflex port are a pair of KEF’s power-
ful new 100mm (4”) long-throw bass/midrange drivers, adding
real depth and weight to the soundscape. The timbre match
with other Codas is of course perfect -
and the terminals are twinned to accom-
modate bi-wiring and bi-amplification to
get the most out of your system.
When you combine innovative ideas with
immaculate execution, the effect can be
amazing: in the case of Coda 80, it’s sound so clear
you can almost see it.
The smooth curves of the one-piece cast aluminium
chassis on which the drive units are mounted hint
at the technical sophistication of what’s inside.
KEF’s large, musically voiced metal dome tweet-
er is what gives the new range its fluency in
reproducing vocals, especially with the latest digi-
tal audio and AV formats.
Bass performance is equally compelling, thanks to
new state-of-the-art long-throw drivers with cop-
per pole pieces. As a highly conductive material, the
introduction of copper caps into the magnetic circuit
increases the eddy currents induced near the surface of each
drive unit, giving a hefty boost to its acoustic output and reduc-
ing distortion by up to 20dB.You’ll
also notice the unique
side-firing subwoofer that endows
Coda 90 with such superlative
bass response.
Diffraction from sharp cabinet
edges inevitably influence a speak-
er’s performance - an acoustic ‘shelving’ effect causes an
audible ‘lump’ somewhere around 600Hz in the mid-
frequency range. Most manufacturers accept this as
a necessary limitation of budget speakers, but KEF
engineers have succeeded in designing out this
unevenness in the new Coda range by adding an
extra filter section in the high order crossover cir-
cuit.
Great attention has also been paid to the structural integri-
ty of the enclosures. Engineered from ‘heavy’ MDF to
increase vibrational inertia, the cabinets are further
strengthened by a combination of internal bracing and an
ingenious tie-rod system which anchors the die-cast chassis to
the back panel of each cabinet.
All models are magnetically shielded to
avoid interference with your other AV
and home entertainment electronics,
and come with bi-wire terminals as
standard. Cabinets are finished to furni-
ture standards in a choice of hand-
picked real wood veneers: Maple or Black Ash.
