1 A Quick Start Set-up Guide
Now that you have your new Genesis 6.1 Surround Channel, we realize
that you can’t wait to hook it up and start playing! However, please read
this quick set-up guide (even if your dealer is setting it up for you) before
you proceed.
1.1 Unpacking
Your loudspeakers will come to you in a large shipping carton weighing
over 43lbs (20kgs). Use correct lifting techniques when moving the
speaker carton around or lifting the speaker out of its carton. We will not
be held liable for damage to either the speakers or your backs during
unpacking and setting up.
1.2 Placement
If you are hanging the speakers on the wall, you will need a qualified
installer to mount them on very strong brackets. The speakers weigh
38.5 pounds (17.5kgs) each, and can cause death or severe injury if it
falls on someone! We suggest either brackets that we supply for flat-wall
or corner mounting, or your installer may be able to recommend other
forms of mounting.
1.3 Connections
The speakers should be connected directly to the speaker-level output
of your power amplifiers using high quality speaker cables and the 5-
way binding posts.
The high-level thru-put binding posts on the speaker are for connecting it
to a subwoofer. We recommend the Genesis ServoSub™ 2/12t as the
perfect complement to this speaker. The S2/12t is designed for corner or
sidewall loading – making it the ideal companion for a surround
loudspeaker.
1.4 Adjustments
The G6.1sr has two knobs on the back – one sets the tweeter level, and
the other switches the speaker between dipole, monopole, and remote-
switchable operation modes. Set the tweeter level to the 12 o’clock
position and the mode to monopole.
Once you familiarize yourself with its performance, putting a little bit of
additional effort into tuning the speaker properly for your system (which
includes the room), will give you greater long-term enjoyment and
benefits.

2 Setting up
2.1 Positioning
A good starting position is for the G6.1sr to be placed horizontally
about 48 inches from the floor and approximately 10 degrees behind the
listener, and at the same distance from the listener as the main L/C/R
speakers.
Use a good quality stand that is solidly built and as rigid as possible, or
hang the speakers on extremely strong brackets on the wall. The
Genesis ServoSub™ 2/12t is a unique subwoofer that complements the
G6.1sr to turn it into a full-range absolute fidelity™ system.
On the home theatre processor, set the speaker to “LARGE” as the
G6.1sr will play to below 60Hz even without a subwoofer.
2.2 Loudspeaker Controls
The two knobs at the top of the plate on
the back of the speaker tailor the high-
frequency response of the G6.1sr and
determines the mode of operation.
2.2.1 Tweeter Control
The tweeter control is subtle with only a
one dB range, but it can make a great
difference in gaining that last bit of additional performance in tuning your
speakers for the system in which you are using them. They can turn
your system from very good to exceptional, so take the time to work
through this process.
The left knob marked TWEETER is a volume control for the front tweeter.
Turning this control clockwise will increase the level of the tweeters. Use
this control if you need a bit more treble, or to increase the apparent
space of the soundstage. Too high a tweeter level, and you can feel that
voices are too sibilant. With music, crashing cymbals are leaping out at
you, and nylon stringed guitars sound steely. Start with this control at the
12 o'clock position. There is about a ±1dB range for this control.
2.2.2 Mode
The G6.1sr is a monopole/dipole surround speaker.
When used primarily to reproduce movie sound effects, the speaker can
be used in dipole mode. When set as such, the speaker sounds
ephemeral and diffused. The G6.1sr incorporates a unique phase
shifting crossover when used in dipole mode. In most surround

loudspeakers, bass is sacrificed when the speaker is switched to dipole
mode. In the G6.1sr, however, the crossover splits the frequency at
around 200Hz. The frequencies above 200Hz are inverted in phase,
while the frequencies below 200Hz are kept in phase. This accounts for
the phenomenal bass performance of this absolute fidelity surround
speaker.
For most music and even Dolby Digital™ and DTS™ use, we
recommend that you switch the speakers to monopole mode. We
prefer this even for movies because the rear and surround
channels typically produce more music and voices than sound
effects even when watching DVDs.
When set in remote switchable mode, a 12V signal applied to the
inner terminals at the bottom of the back-plate switches the speaker
to dipole mode. The default mode is monopole.
2.3 Tuning the system
The best way to tune your system is to use music to tune the front
left/right speakers. This way, you will have a system that will deliver
audiophile quality playback. Then, using a full-range pink noise signal
that can be generated by your player, processor, or a test disc, match
the surround and center channels to the front left/right reference.
The ear is a phenomenal measuring instrument. With a little practice, it
will be easy to distinguish subtle differences in sound. The easiest way
is to use a circular pink noise pan, like on the Chesky Ultimate Surround
Set-up and Test DVD-Audio disc. The pan should sound seamless on a
well set-up system.
Every listening room is different, and we recommend that you take the
time to carefully tune the system for the environment in which it is
placed. Due to room idiosyncrasies, do not be afraid to set the left and
right speakers to different levels.
Setting the tweeter level at the “12 o’clock” position is “normal” and will
be the position from which you can start tuning. With the controls in this
position, they may not sound perfect, but your Genesis loudspeakers will
sound great straight out of the box.
If you have any questions, feel free to contact us at Genesis. Our
website is the first place you can look to for more information, but you
are welcome to either send us an email, or just give us a call!

3 The Technology used
3.1 The Transducers
The transducers in the 3-way G6.1sr are all proprietary Genesis-
designed drivers manufactured to our exacting standards:
3.1.1 The Genesis Ribbon Tweeter
Reviewers in the audiophile press have often remarked that the Genesis
circular ribbon tweeter is the world’s best. It is a one inch circular planar
ribbon design crafted from an extremely thin membrane of Kapton® with
a photo-etched aluminium “voice coil” that is a mere 0.0005 inch thick.
The entire radiating structure has less mass than the air in front of it!
That is why it will accurately reproduce frequencies beyond 36 kHz.
The result of this design is a driver that has a rapid and uniform
response to high frequencies and has the speed of the best
ribbon/electrostatic designs, without the high distortion and poor
dispersion that is typically associated with them.
The G6.1sr uses three of these tweeters per channel, one on each of
the front three faces. In monopole mode, only the front tweeter is
employed. In dipole mode, the front tweeter is switched off, and the
tweeters on the two side faces are turned on but out of phase to one
another.
3.1.2 Titanium Midrange
We sometimes say that the midrange is a window into the mind of a
composer or a singer. And indeed, the midrange is where the “magic” is
in a well-recorded musical event.
The G6.1sr uses a Genesis-designed proprietary 5 inch titanium-coned
midrange to cover this critical frequency spectrum. Manufactured out of
one of the lightest and stiffest materials known, this low mass cone
driver is one of the best midrange transducers ever made, with nearly
instantaneous transient response, enabling the G6.1sr to sound lifelike
and effortless.
The midrange is switched off in dipole mode.
3.1.3 Aluminum-cone Woofers
The G6.1c incorporates two 6.5 inch metal cone woofers. Made of a
cone of solid aluminium, the suspension and voice-coil have been
maximized for long, distortion-free excursion so as to increase dynamic
range. Our aluminium cones are a magnitude stiffer than plastic or

~ÄëçäìíÉ=ÑáÇÉäáíó
paper cones, and virtually eliminate the problems caused by cone
bending and break-up.
The woofers work in either monopole or dipole mode. When the G6.1sr
is switched to dipole mode, a unique phase shifting crossover channels
the midrange frequencies above 200Hz to these woofers, running them
out of phase.
The frequencies below 200Hz are kept in phase in order to maintain the
bass response of these speakers.
3.2 Crossover
The crossover is the brain of the loudspeaker. In order to manage and
maximize the performance of the extensive complement of transducers
used in Genesis loudspeakers, we spend more money on the crossover
than many other manufacturers put in their entire speaker even at the
same price range.
Each crossover is designed by computer modelling plus years of
knowledge and experience. The inductors are designed and made for
Genesis with OFC copper windings. The capacitors used are also
custom made for Genesis, using high-quality polypropylene-film and tin-
foil. The crossovers in each G6.1sr weighs over seven pounds (3.2kg)!
More importantly, the crossovers are designed with many, many hours
of music listening and constant refining, tuning and tweaking of the
circuit. Out of this comes the “magic” that is a Genesis-designed
loudspeaker system. For example, by going the more expensive route
of using several smaller capacitors in parallel instead of a single large
one, transparency and musicality were improved.
The G6.1sr actually employs three totally separate crossovers. This
accounts in part for its absolute fidelity performance. In monopole mode,
a single 3-way crossover powers the front tweeter, midrange, and two
woofers.
When set in dipole mode, two crossovers are used. One drives one face
of the speaker with a tweeter and woofer. The other is a unique phase-
shifting crossover that splits the frequency range at approximately
200Hz. The frequencies above this are driven out of phase to the other
face, creating the dipole effect. The frequencies below 200Hz are in
phase to the other face in order to maintain the bass performance.

3.3 Vibration-free Cabinet
The cabinet was designed for aesthetics, but with an obsession to sonic
quality, vibration control, structural strength and rigidity.
In some parts of the cabinet where vibration would have been the
greatest, 1½ inches (36mm) of multi-layer bonded MDF was used to
provide damping, structural integrity and a rigid platform for the drivers to
be located. Extensive bracing was carefully incorporated using 12mm
slabs of MDF to eliminate cabinet flex and panel resonance.
Incidentally, MDF was chosen as the material of choice for its damping
properties and its consistency in hardness, density and rigidity. It would
actually have been cheaper and easier to make the cabinet of solid
wood, but that would have been a compromise.
Genesis designed a unique tongue
and groove joint in order to improve
the structural rigidity of the cabinet.
Crystalline glue the dissolves into the
mdf was chosen to ensure that the
interfaces between two panel pieces
becomes as one. This results in the
entire enclosure behaving as a single
unit, with seemingly no discontinuity in
material.
This results in a joint so strong that
when you try to rip the joint apart, it
isn’t the joint that would break. The
mdf would break apart first.
