INTRODUCTION TO THE
EXQUISITE GRAND COLLECTION
Diamond concave tweeter
The diamond tweeter used in the Exquisite
series is a true technological wonder. The
tweeter has a diamond cone which has been
realizedbythesocalledCVDprocess.Withthis
process incredible stiffness is reached with a
minimum of thickness of only 50 μm. Notice a
human hair is in the range of 17 to 180 μm.
The cone is the most essential part of the
tweeter and because this cone is made of
Diamond the tweeter is capable to create
impressively pure high frequencies.
Kharma Omega 7 driver
We use our in-house developed Kharma
Omega 7driver, where the number isreferring
to the 7-inch size of this carbon based driver.
The newcone technology usedfortheOmega
7 driver isbased onUltraHigh Moduluscarbon
fibers, which is the best fiber available today.
The useof theseultra-stiffcarbonfibers andan
unique resin displaces the break-up
frequencies of the cone, in comparison with a
standard cone material, to a whole new level.
These increased break-up frequenciesensure
the cone is free from almost all resonances in
the intended frequency range for this
midrange driver. Moreover, the cone shape is
optimized with a finite element analysis to
utilize the full potential of the carbon material.
This combination of the best carbon fiber and
an optimizedcone shapehasresulted ina near
perfect behavior for the Kharma Omega 7
driver.
Kharma Omega 7F driver
Some of our systems are equipped with our
exclusive KharmaOmega7F midrangedrivers
and incase of theMidiGrand also Omega11F
drivers. The F stands for 0-Foucault currents,
which is a novelty in the audio world, because
for the first time no iron is used in the magnet
motor-system, avoiding any interaction.
Normally the voice coil induces a Foucault-
current into the iron parts and that current
induces distortion into the driver-coil which
will distort the original signal by definition. This
is now completely gone and the result is a
higher resolution, more micro-dynamics,more
macro-dynamics,fastertransients,morericher
spectrum of tonal variations from the music
itself, more natural sounding, more explosive
sounding, more realistic sounding.
Nomex-Kevlar driver
The woofers have 11 inch and 12 inch
sandwich-honeycomb-Kevlarconeswhichalso
again are completely free from structure born
resonances in the used frequency range.
Cabinet
The cabinet of the Grand Collection is
constructed of 40mm thick high pressure
laminate.
Crossover
This Exquisite loudspeaker can only achieve
astonishing musicality by using complex
crossovertechniques,whichcanbeseenasthe
beating heart of this loud speaker.
Thiscomplexin-housedevelopedcrossoverwill
lead all drivers to the right music composition.
Therefore the crossover can be seen as an
orchestra conductor, which will have to turn
the information received through the
loudspeakercableintoamusicalspectacleasif
it was read from a music sheet. Kharma has
mastered the art of retaining musical
wholeness with the proprietary crossover
technique used throughout the Exquisite
series. This technique is seldom used byother
manufacturersbecauseofitscomplexity. This
results in a Kharma crossover where there is
simply no gap in information.
Stand
Mechanical residual vibrations of the cabinet
are terminated by the Spike Disk Suspension
System(SDSS)byminimizing thecontactarea
between the cabinet and the floor. The SDSS
stand also provides a fixed and levelled
orientation for the cabinet drivers, as each
spike can be adjusted individually in the
vertical direction.
