Tilting the Speakers Backwards and Forwards—As the
diagrams show in the Dispersion Interactions section of this
manual, the vertical dispersion is directional above and below
the stator panel itself. In some instances, if you are sitting close
to the floor, slight forward tilting of the speakers can enhance
clarity and precision.
Imaging—In their final location, your speakers can have a
stage width somewhat wider than the speakers themselves.
On well recorded music, the instruments can extend beyond
the edges of each speaker (left and right), yet a vocalist should
appear directly in the middle. The size of the instruments
should be neither too large nor too small, subject to the intent
and results of each unique audio recording.
Additionally, you should find good clues as to stage depth.
Make sure that the vertical alignment, distance from the front
wall, and toe-in is exactly the same for both speakers. This will
greatly enhance the quality of your imaging.
Bass Response—Your bass response should neither be
one note nor should it be too heavy. It should extend to the
deepest organ passages and yet be tight and well defined.
Kick-drums should be tight and percussive—string bass notes
should be uniform and consistent throughout the entirety of
the run without booming or thudding.
Tonal Balance—Voices should be natural and full and cym-
bals should be detailed and articulate yet not bright and
piercing, pianos should have a nice transient characteristic and
deep tonal registers. If you cannot attain these virtues, read
the section on Room Acoustics. This will give you clues on
how to get closer to these ideal virtues.
Final Placement
After the full break in period, obtaining good wall treatments,
and the proper toe-in angle, begin to experiment with the dis-
tance from the wall behind the speakers. Move your speaker
slightly forward into the room. What happened to the bass
response? What happened to the imaging? If the imaging is
more open and spacious and the bass response is tightened,
that is a superior position. Move the speakers back six inches
from the initial setup position and again listen to the imaging
and bass response. There will be a position where you will
have pinpoint imaging and good bass response. That position
is the point of the optimal placement from the front wall.
Now experiment with placing the speakers farther apart. As
the speakers are positioned farther apart, listen again, not so
much for bass response but for stage width and good pinpoint
focusing. Your ideal listening position and speaker position
will be determined by:
• Tightness and extension of bass response
• Width of the stage
• Pinpoint focusing of imaging
Once you have determined the best of all three of these
considerations, you will have your best speaker location.
The Extra "Tweak"
This extra "tweak" may be useful when your speakers are
placed in a dedicated listening room. Use the following pro-
cedure and measurements for your speakers placement to see
what can happen to your system's performance. These formu-
las will help determine optimum placement of your speakers
to minimize standing waves.
1
Distance from the front wall (in front of the listening
position) to the center of the curvilinear transducer: To
determine distance from the front wall, measure the ceil-
ing height (inches) and multiply the figure by 0.618 (i.e.
ceiling height (inches) x 0.618 = the distance from the
front wall to the center of the curvilinear transducer).
2
Distance from the side-walls to the center of the curvilin-
ear transducer: To determine distance from the side walls,
measure the width of your room in inches and divide by
18. Next, multiply the quotient by 5 (i.e. room width in
inches / 18 x 5 = the distance from the side-walls to the
center of the curvilinear transducer).
Enjoy Yourself
Your speaker is very refined and benefits from care in setup.
With these tips in mind you will find, over your months of
listening, that small changes can result in measurable dif-
ferences. As you live with your speakers, do not be afraid to
experiment with their positioning until you find the optimal
relationship between your room and speaker system that gives
to you the best results. Your efforts will be rewarded.
