An instructional video outlining the Wilson Audio Setup Procedure (WASP)
can be found here: wilsonaudio.com/WASP. The proper positioning of your new
Sabrina within your room is critical in order to extract its formidable perfor-
mance envelope. When carefully followed, the WASP has proven to be the most
effective method for setting up Wilson loudspeakers. Your authorized Wilson
dealer is trained in this process, and is the best resource for you to ensure your
loudspeakers are set up properly.
Viewing the video is the best way to learn how to properly employ WASP,
but we have also included an outline of it here.
Zone of Neutrality: Left and Right Channel
The “Zone of Neutrality” is an area in your room where the speakers will
sound most natural. This location is where the speakers interact the least with
adjacent room boundaries. It is important to have a clear working space while
determining the Zone of Neutrality.
The following is a simple method to locate the Zone of Neutrality within
your listening environment:
1. Stand against the wall BEHIND the location where you intend
to position your loudspeakers. Speaking in a moderately loud
voice and at a constant volume, project your voice out into

Section 1.1—WASP 7

the room. Your voice will have an overly heavy, “chesty” quality
because of your proximity to the rear wall.
2. While speaking, slowly move out into the room, progressing in
a direction parallel to the sidewall. It is helpful to have anoth-
er listener seated in the listening position to assist you during
this process. Listen to how your voice “frees up” from the added
bass energy imparted by the rear wall boundary. Also notice
that your voice is quite spatially diffuse (to your assistant, your
voice will sound spatially large and difficult to localize) as you
begin to ease away from the rear wall.
3. At some point during your progression forward into the room,
you will observe a sonic transition in your voice; it will sound
more tonally correct and less spatially diffuse (your assistant
can now precisely localize the exact origin of your voice). When
you hear this transition, you have entered the inner edge of
the Zone of Neutrality. Place a piece of tape on the floor to
mark this location. Although it will vary from room to room, in
most rooms the zone begins between two and a half to three
feet from the rear wall.
4. Continue to walk slowly away from the rear wall. After some
distance, usually one to two feet past the first piece of tape,
you will begin to hear your voice lose focus and appear to

reflect (echo) in front of you. This is caused by the return of the
room’s boundary contribution; your voice is now interacting
with the opposite wall. At the point where you begin to hear
the reflected sound of your voice, you have reached the outer
edge of the Zone of Neutrality. Place a piece of tape on the
floor and mark this location. The distance between the “inner”
and “outer” edge tape marks is usually between eight inches
(for small, interactive rooms) and three feet (for large, more
neutral rooms).
5. Now position yourself against the side wall perpendicular to
the intended speaker location. Stand between the two tape
marks. Using the same procedure as above, begin moving into
the room toward the opposite sidewall, progressing between
the two pieces of tape. As above, listen for the point in the
room where your voice transitions from bass-heavy and diffuse
to neutral. Mark this point with tape. Continue your progres-
sion until there is an obvious interaction with the opposite
wall in front of you and mark this point with tape. The four
pieces of tape now form a rectangle that establishes the Zone
of Neutrality for the loudspeaker to be installed on that side of
the room. Using the four marks as your guide, tape an outline
to define the boundaries of the rectangle.

Section 1.1—WASP 9
Wilson Audio Specialties
6. Repeat this process for each speaker location individually.
These are your Zones of Neutrality, one for each channel.
Theoretically, the Zone of Neutrality for any room runs like a path, paral-
lel to the walls all around the room. Adjacent to very large windows and open
doors, the outer edge of the Zone of Neutrality moves closer to the wall and be-
comes wider. If you were to extend the inner and outer boundaries of the Zone
for the sidewalls and the front wall (behind the speakers), they would intersect.
Speaker Placement Versus Listening Position
The location of your listening position is as important as the careful setup
of your Wilson Audio loudspeakers. The listening position should ideally be no
more than 1.1 to 1.25 times the distance between the tweeters on each speaker.
Therefore, in a long, rectangular room of 12’ x 18’, if the speaker tweeters are
going to be 9’ apart, you should be sitting 9’11’’ to 11’3’’ from the speaker. This
would be more than halfway down the long axis of the room.
Many people place the speakers on one end and sit at the other end of
the room. This approach will not yield the finest sound. Carefully consider your
listening position. Our experience has shown that any listening position that
places your head closer than 14” from a wall will diminish the sonic results of
your listening due to the deleterious effects of boundary interaction.

When carefully followed, the WASP has proven
to be the most effective method for setting up
Wilson loudspeakers.

Section 1.1—WASP 11
Wilson Audio Specialties
Speaker Orientation
Speaker placement and orientation are two of the most important consid-
erations in obtaining superior sound. The first thing you need to do is eliminate
the sidewalls as a sonic influence in your system. Speakers placed too close to
the sidewalls will suffer from a strong primary reflection. This can cause out-
of-phase cancellations, or comb filtering, which will cancel some frequencies
and change the tonal balance of the music. Adhering to the Wilson Audio Setup
Procedure outlined in the previous section is the best method with which to
position your loudspeakers.
A very important aspect of speaker placement is how far from the back
wall to place the speakers. The closer a loudspeaker is to the back wall, the more
pronounced the low bass energy and centering of the image will be. However,
this comes at a definite reduction in stage size and bloom as well as a deteriora-
tion of upper bass quality. You must find the proper balance of these two fac-
tors, but remember, if you are partial to bass response or air and bloom, do not
overcompensate your adjustments to maximize these effects. Overcompensated
systems are sometimes pleasing in the short-term, but long-term satisfaction is
always achieved through proper balance.

equipment, Wilson Audio has measured the correct geometric time domain
alignment for different distance/ear height combinations. See the next section
for details. By measuring the distance from the speaker to the your ear when
seated in the listening position, as well as height of the listener’s ear measured
from the floor, you will be able to align the system for your listening position.

Note: To avoid damaging the Sabrina’s painted surface. Please remove any
jewelry such as rings, watches, necklaces, and bracelets during this process.
Initial Check
The Sabrinas are shipped in boxes. Upon receiving these boxes, please
check their condition. If any of the boxes are damaged, please report it to the
shipping company immediately for insurance verification.
The following items are recommended for this procedure:
• Box Cutter
• Phillips head drive bit
• Masking tape (for use in speaker setup)
Uncrating the Sabrina
A minimum of two strong adults is required to set up the Sabrinas.
1. Carefully cut the metal bands around the box.
2. With the box facing up, carefully cut the tape securing the lid.
Slide off the outer cardboard shell.

3. One box will contain the tool kit. Carefully remove the toolkit
and the manual. Set these aside
4. Carefully lift the box upright so that the Sabrina is now verti-
cal. With the Sabrina’s bottom toward the floor and one person
holding the box, the second person should reach in and gently
slide the Sabrina out of the box.
5. Place the Sabrina with an odd serial number on the left side of
the room and the Sabrina with an even serial number on the
right side of the room.
Note: The Sabrinas are very heavy and care should be taken to prevent injury.
