Genesis Advanced Technologies 6 Series - Manual (Page 2)

TECHNOLOGY
The technologies and materials used in the
Genesis 6-Series far surpass what is merely
necessary. With over 40 years of experience in
loudspeaker design, Genesis has a legacy of
experience and knowledge to draw from to achieve
a level of performance that is simply astounding.
DIPOLAR RADIATION PATTERN
What many people have begun to realize is that
the room is as big a part of their music system as
are the loudspeakers. All rooms have floors, ceilings
and sidewalls that distort sound because of lateral,
early-arriving reflections at the listening positions.
Dipoles radiate the same waveform from both
front and rear in "push/pull" fashion. Thus, the
sound waves from the front and back of the speakers
cancel out as they radiate from the sides and tops
of the speakers. With fewer spurious reflections to
confuse hearing, imaging is more stable, sharply
focused, deeper, and spacious. Transients are clearer,
and sharper.
This control of dispersion and reflected sound
is the secret behind how Genesis loudspeakers
manage to "disappear", and gets out of the way of
your enjoyment of music.
LOW DISTORTION DRIVERS
Transducers used in the 6-Series loudspeakers
all speak with a similar voice.
The renowned Genesis 1-inch circular ribbon
tweeter covers the high frequency duties. This
tweeter has been often been called “the world’s
SERVO-CONTROLLED BASS AMPLIFIER
Inertia is the enemy of accurate low frequency
reproduction. The woofer must start instantly, and
stop suddenly. However, its inertia makes it sluggish,
resulting in bass
overhang, bloat,
lack of tightness,
and a blurring of
dynamic impact.
Rather than
simply send the
woofer pulses of
power, and hope
for the best, the solution is to use a precision
accelerometer to monitor the woofer’s movement
and make instantaneous corrections, even when it
includes complex, rapidly evolving musical bass
lines or cinema special effects.
This system places extraordinary demands on
the amplifier, since the system uses enormous
amounts of current to precisely control the woofer.
Genesis’ ultra-efficient Class-D discrete MOSFET
switching amplifier is a prime example of intelligent
power application. The Class D design provides
exceptional control and thermal stability even when
playing the most demanding sources at high volume.
With this servo control, the transducers appear
massless and anechoically flat. While typical non-
servo woofer systems have distortion levels that
exceed 10% at even moderate levels, the Genesis
servo bass system reduces this distortion to below
one percent at almost any output level.
PHASE COHERENT CROSSOVERS
If the servo-controlled bass amplifier is the heart
of the loudspeaker, the crossover is the brain. In
order to manage and maximize the performance of
the extensive complement of transducers used in
the Genesis 6-Series, we use our own custom made
best”. The membrane is crafted from an extremely
thin sheet of Kapton, with a photo-etched “voice
coil” that is a mere 0.0005 inches thick. The entire
radiating structure has less mass than the air in
front of it, enabling the Genesis tweeter to accurately
reproduce frequencies beyond 35kHz.
In order to match the exemplary transparency
and speed of the ribbon tweeter, the midrange driver
in the 6-Series uses a cone made of solid titanium
– one of the lightest and stiffest materials known.
This low mass cone is capable of nearly
instantaneous transient response enabling the 6-
Series to sound effortlessly lifelike.
Two 6.5-inch mid-bass couplers provide vast
dynamic range to the 6-Series. Designed of extremely
light and stiff aluminum, the solid
metal cones are capable of handling
huge power and transients. Using
metal cones within very tightly
controlled frequency ranges, Genesis
achieves extremely low coloration
and distortion at all levels.
Woofers have to move forcefully
to produce the lowest frequency
sounds. This results in a large
dynamic load on the surface of the
cones. Genesis uses precisely
ribbed and contoured aluminum
cones that are free from transient-
blurring distortion imposed by lesser materials.
These have absolutely no breakup modes within
their operating bandwidth, and deliver “floor-
shakingly musical bass”.
parts, including the finest capacitors using the best
polypropylene film and tin-foil technology available
today. Our custom-designed inductors are among
the best that the industry can offer.
Each crossover is designed by extensive use of
computer modeling, plus years of knowledge and
experience. More importantly, the crossovers are
tuned, refined, and tweaked with many, many hours
of listening. From this, comes the magic of pinpoint
imaging and soundstage recreation.
CABINET CONSTRUCTION AND FINISH
In order to achieve both the sonic quality
demanded by a Genesis product, as well as the
subtle elegance and understated beauty that we
sought to achieve, the cabinet sides of the G6.1 had
to have a complex curve and angled by 1 degree
from top to bottom, and 3 degrees from front to
back. The front baffle also had to slope back by 5
degrees from bottom to top.
Even the pieces that make up the internal braces
were machined to the ideal angles to fit perfectly.
The result is a beautiful-looking cabinet that is free
from uncontrolled vibrations and resonance. The
cabinets of the other products of the family are
engineered to match.
Rare natural wood veneers were
sourced to complement the look –
not artificially reconstituted “real
wood fiber” veneers. Hence, no
two pairs of veneered Genesis
loudspeakers will look identical.
For the modern décor, high
gloss finishes are also available
in any color under the sun. In
order to ensure a deep luster and
color fastness, the highest quality
automotive paints are used with
an exacting 7-step process.
