Genesis Advanced Technologies 5 Series Portable Speaker User Manual


 
TECHNOLOGY
The technologies and components used in the
Genesis 5-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.
LOW DISTORTION DRIVERS
Transducers used in the 5-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
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 5-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 5-
Series to sound effortlessly lifelike. Using metal
cones within very tightly controlled frequency
ranges, Genesis achieves extremely low coloration
and distortion at all levels.
mass-less 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.
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 get out of the way of
your enjoyment of music.
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
5-Series, we use
custom made
parts; including
the finest
capacitors
available.
Instead of
aluminum foil, Genesis uses tin and polypropylene
in many of our capacitors as they sound better! Our
custom-designed air-core inductors using oxygen-
To marry the exceptional midrange to
the bass, a 6.5-inch aluminium-cone mid-
bass coupler is used. Designed to be
extremely light and stiff, the solid metal
cones are capable of handling huge power
and transients. Used in the tight frequency
band between the midrange and the
woofers, these cones work as a perfect piston to
deliver uncolored and distortion-free sound.
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 profoundly powerful bass capable of
shaking a large room.
SERVO-CONTROLLED BASS AMPLIFIER
Inertia is the enemy of accurate low frequency
reproduction. The woofer must start instantly and
stop exactly. However, the inertia of the moving
structure 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 switching amplifier is a
prime example of intelligent power application. The
Class D design is extremely efficient and provides
exceptional control and thermal stability even when
playing the most demanding sources at high volume.
With this servo control, the transducers appear
free copper windings 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 highly
focused imaging and soundstage recreation, spectral
coherence, and accuracy of timbre.
With the trim pots for midrange and tweeter, the
Genesis 5-Series is one of the most adjustable,
tuneable speakers on the market.
CABINET CONSTRUCTION AND FINISH
The form, construction, and fit and finish of the
cabinet contribute to the fidelity of the loudspeaker.
In the 5-series main loudspeaker, the tweeter
and midrange are housed in a truncated, tapered,
four-sided prism with rounded
corners. This means that the drivers
interact minimally with the cabinet
because of the narrow width and
lack of sharp edges.
The mid-bass and woofer
enclosure is exactly sized to
ensure the proper bass extension
from the dipolar-mounted out-of-
phase mid-bass couplers and the
in-phase woofers. The result is
stunning bass extension from a
compact box.
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. Our High Gloss black is a true hand-
rubbed piano lacquer. Over 7 coats of wax are used
to achieve a deep luster that rivals the most
expensive grand piano.
