Subtle angles and complex curves are used to create an optical illusion that makes the G6.1 look smaller and slimmer than it actually is. The veneers are also carefully chosen to reflect and enhance these curves and angles.
1.2 Room Placement A good starting position for your G6.1 is about 18 inches (46cm) into the room as measured from the front wall (the wall you look at as you are seated listening to the speakers) to the back of the base of the speakers.
8’ to 10’ 1.3 Power Requirements The G6.1 has a bass section powered with a highly efficient 500W amplifier. Each speaker is capable of drawing over 5 amps at 110V or 2.5 amps at 240V. We recommend that each speaker be plugged directly into a dedicated power socket.
LFE IN of the speaker. 1.5 Adjustments Don’t be too worried by all those knobs on the back of the G6.1. Just set all knobs to the 12 o’clock position. That is a good place to start. The G6.1 will sound great, straight out of the box, set-up like this.
2 Complete Set-up Guide 2.1 Positioning A good starting position for the G6.1 is about 18 inches (0.45m) into the room, as measured from the front wall (the wall you look at as you are seated listening to the speakers), to the back of the base of the speaker.
2.3.2 Alternative Input Connection You may wish to connect the bass section of the G6.1 directly to your preamplifier instead. You may wish to do this if you know that your power amplifier does not have a flat response down to below 20Hz.
There is no need to do this if you think that your power amplifier does not have the power to drive the woofers. This is because the G6.1 has a rising impedance below 150Hz, and the built-in amplifier off-loads your power amplifier for the bass.
~ÄëçäìíÉ=ÑáÇÉäáíó make the soundstage more forward. There is about a one and a half dB range for this control. 2.4.2 Bass Control The knobs in the middle of the amplifier plate on the back of the speaker control the servo-controlled bass amplifier. The knob in the middle marked controls the volume of the built-in bass servo amplifier.
Music is the best way to begin your set-up procedure. We suggest that video sources be used only after you have set-up the system to properly reproduce music. There is no “perfect” setting for the G6.1 loudspeaker. Every listening room is different, and we recommend that you take the time to carefully tune the system into the environment it is placed in.
~ÄëçäìíÉ=ÑáÇÉäáíó In rooms with solid concrete or brick walls and floors like in Asia and Europe which have very little bass loss, you may need to turn this down to 76Hz in order to reduce bass boominess. Next, set the woofers using more than just a voice. Select some music that you know to have good deep bass.
~ÄëçäìíÉ=ÑáÇÉäáíó 1/3 of the way into the room is about as far as you want to go. Pulling them half-way into the middle of the room is unlikely to help. Find the best compromise for your room, your tastes and your space requirements.
~ÄëçäìíÉ=ÑáÇÉäáíó 4 The Refinement stage After following the set-up guide above, you may not be completely satisfied with the results. We share with you here some of our observations in setting up these loudspeakers. 4.1 One Change at a Time One rule of thumb you should always keep in mind.
~ÄëçäìíÉ=ÑáÇÉäáíó the midrange driver. This would tend to sound "boomy" in the mid bass regions. Another good rule of thumb is to first set the B control of the woofer for proper mid-bass rather than low bass. The theory is that if the mid-bass is correct, then the low bass should be very close to correct.

~ÄëçäìíÉ=ÑáÇÉäáíó Sidewalls. Because the speaker is a dipole it is less sensitive to the sidewalls. However, as a rule of thumb it is a good idea to keep the speaker as far away from the sidewalls as is practical. In some rooms, it may be helpful to add some damping material or diffuser panels to the point of first reflection.

In essence, the G6.1 has a servo-controlled subwoofer already included in each speaker. This capability allows the G6.1 to provide the ability to reproduce the low frequency effects (LFE) signal available on all modern movie decoders.
5.3 LFE Output Along with the LFE input, the G6.1 has a unique capability of LFE output. This buffered output can be used to daisy-chain the LFE signal to other LFE inputs including other G6.1 speakers and separate subwoofers.

~ÄëçäìíÉ=ÑáÇÉäáíó 6 The Genesis 6.1 Technology 6.1 The Servo-bass Advantage Very few loudspeakers use servo drive, either because most designers think that it is too difficult to design, too expensive or because of the extraordinary demands a servo system makes on the amplifier and the transducer.
The G6.1 also uses the wall behind the speaker to give more depth to the soundstage and “air” to the speaker without detail robbing room reflections from the sidewalls.

The G6.1 uses two of these tweeters per channel. One front-firing, and the other rear-firing wired to the crossover out of phase to the front tweeters, creating a dipole.

SPLs as well as the least vibration in the cabinet. All four woofers in a pair of G6.1’s work in-phase to control the air mass of the listening room. This means that the surface area of the four cones and the loudspeaker enclosure all work in unison to produce bass output that descends evenly to below your hearing limits.

One side benefit of this powered woofer system is that almost any sized amplifier (within reason!) can be used to drive the G6.1. The unique design of the G6.1 means that it has rising impedance below 180Hz, relieving the power amplifier to drive just the speakers from about 200Hz and up;...

Try this as a party trick for the optical illusion in the G6.1: the rear grill looks like it has parallel sides when you are looking at it – but when you take it out, and try to put it back in upside down, it’s impossible.

~ÄëçäìíÉ=ÑáÇÉäáíó 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 locates the mid-bass, midrange and high frequency transducers on a gently sloping front.
