Set up guide
for The Genesis 928 Subwoofer
Introduction
While many companies have rushed to fill the growing home theater market with quick
redesigns of existing products, a few companies have taken their time to do it right.
Our goal in the design of both a high end music and home theater product was to set a
new standard of performance for both music and video - a benchmark for the industry.
After many years of designing, listening and redesigning, we believe that we have
achieved our goal in the Genesis 928 subwoofer.
Based on all new technology in both woofer design and the servo controlled power
amplifier, the 928 is a musically accurate design in the tradition of all Genesis reference
loudspeakers. So honest is this speaker's performance that the 928 is equally at home
in the finest music systems as in home theater applications.
The 12 inch woofers employed in the Genesis 928 subwoofer are a custom designed
and proprietary metal cone configuration that exhibits great strength and rigidity with
no cone flexure. The benefits of no cone flexure include extremely low levels of
distortion and zero break up modes within the useable frequency band.
The heart of the Genesis 928 servo subwoofer system is our exclusive accelerometer
based motional feedback servo system. First introduced to high end audio in 1968 by
Arnie Nudell in the legendary Infinity Servo Statik One, servo bass systems continue to
represent the ultimate in low frequency response today.
The concept of servo bass is an easy one to understand. it employs, through the use
of an accelerometer sensor, active feedback which constantly monitors the
performance of the woofer and electronically compares it to the input making
instantaneous corrections.
Without this feedback loop the mass of the woofer is too great to control properly and
distortion occurs. 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.

Positioning the 928 for music
If your primary usage of the 928 is in a music system, we recommend you follow this
setup guide.
We recommend that the 928 be placed behind and to the outside of your main music
speakers. It you only have one Genesis 928 subwoofer, we recommend that you place
it on the right side near the corner. This is not a critical recommendation and you may
place the single subwoofer either on the right or the left. We recommended the right (if
there is a choice) because it the side in an orchestra that the bass instruments are
typically located. In any case try to avoid placing the subwoofer in the center of
your rear wall.
Make sure you do not plug the woofer into a switched outlet. Make sure the Genesis
928 is plugged into a wall outlet that is always on. We recommend against the use of
an extension cord for the AC power. If you are forced to use an extension cord, make
certain it is as heavy a gauge as possible.
Positioning the 92810r Video
There are a number of possible positioning schemes for video applications. Our first
recommendation is that you visit with the dealer you purchased your video sound
system from and get his or her advice.
Typically, in video applications, the front three speakers Left, Right and Center (LCR)
speakers are on stands, are mounted to the wall or many times are the same speakers
used with your music system with the addition of the center channel. Depending on the
availability of space, you may place a Genesis 928 in the front or the back of the
system. If you have a dual purpose system, music and video, you might consider
following the music setup instructions first (if space allows).
In a dual woofer system, it is permissible to place one subwoofer in front and one
subwoofer in the rear to increase the "surround effect" in your video system if you wish.
The Genesis 928, in a video system environment, will typically be placed fairly close to
the wall or in a corner. As with the recommendations for the music system setup try to
not place the subwoofer in the middle of any wall.
Make sure you do not plug the woofer into a switched outlet. Make sure the Genesis
928 is plugged into a wall outlet that is always on. We recommend against the use of
an extension cord for the AC power. If you are forced to use an extension cord, make
certain it is as heavy a gauge as possible.
