Section 1.2—WASP

An instructional video outlining the Wilson Audio Setup Procedure (WASP)

can be found here: wilsonaudio.com/WASP. The proper positioning of your new

Alexx within your room is critical in order to extract its formidable performance

envelope. When carefully followed, the WASP has proven to be the most effec-

tive 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 loud-

speakers 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

Wilson Audio Specialties

Alexx Install ation and Care Guide

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

Authentic Excellence™

S e c t i o n 1 . 2 —WA S P

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.

son loudspeakers.

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.

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.

To make correct in-home set up of the Alexx possible without test equip-

ment, Wilson Audio has measured the correct geometric time domain alignment

for different distance/ear height combinations. See the next section for details.

Authentic Excellence™

S e c t i o n 1 . 2 —WA S P

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.

Section 2.1—Preparation

It is important that the instructions in the following section are followed
and carried out precisely. The Alexx is a precision instrument, capable of
extremely accurate alignment in the time domain if the following process is
meticulously followed.

Note: To avoid damaging the Alexx’s painted surface. Please remove any jew­elry such as rings, watches, necklaces, and bracelets during this process.

Preparation

You will need the following items:

• Supplied hardware kit

• Tape measure

• Known listening position

• Masking Tape

The Upper Array uses the combination of captive spikes and aspherical

“time alignment blocks”. The spikes/block combination rotate the two upper

modules to a prescribed position as a part of the Alexx’s propagation delay ad-

justment. Additionally, the alignment blocks move fore-to-aft to achieve proper

alignment relative to the other drivers. The spikes in the modules also provide

proper coupling of the upper modules to the array. The shorter “A” spikes are al-

ways installed in the front two positions of the two modules (the threaded holes

located on the bottom front of each module). The spike-type is stamped into

the flat surface on the top of each spike. The spikes should be screwed in all the

way, until they are tight.

Section 2.2—Alexx Propagation Delay Adjustment

Optimizing Propagation Delay in Your Room

The Alexx system allows for different listening distances (away from the

speakers) and listening ear heights (measured distances from the floor to your

ear). For each distance/ear height combination there is a unique alignment ge-

ometry.

1. Refer to the Propagation Time Alignment Charts throughout

this section (which can also be found in Section 5 of this book-

let). Propagation Delay Tables are also available on the Wilson

Audio APP, which is available on iTunes and Android Market.

2. Make sure that you are in your intended listening position.

3. While sitting, have someone measure your ear height from the

floor directly below your ear canal. You should be relaxed in

your chair, as you would be when listening to music.

4. Now measure the distance (on the floor) from the point on the

floor below your ear to the base of the loudspeaker.

5. There are four charts for the Lower Midrange Module. The first,

“Alexx Lower Midrange Spike Length,” is a table determining the

rear spike length for the lower module. The second, “Alexx Tweet-

er Detent Position,” specifies the position of the bridge spike into

the detent on the top of the tweeter module. The third, labeled

“Alexx Lower Midrange Alignment Block Position,” determines

the lower midrange alignment block’s front-to-back location. The

fourth, labeled “Alexx Lower Midrange Alignment Block Step,”

specifies the step on which the lower-midrange module’s rear

spike will rest.

6. There are three charts for the Upper Midrange Module. The first

is labeled “Alexx Upper Midrange Spike Length”, indicating which

spike to install in the rear of the upper module. The second is

Section 2.8—Connecting the Upper Modules

The Alexx uses binding posts that were designed in-house and are manu-

factured exclusively for Wilson Audio. The design goal was to create a connector

with superior overall sound quality, consistency, and longevity.

A note about these connectors: You risk breaking the binding post if they
are overtightened. Use the supplied binding post wrench and tighten until
just snug.

The cables for the upper modules are labeled so that they can be easily

attached to their appropriate module. This is accomplished as follows:

1. Locate the cable marked “Lower Mid.” Connect this cable to the

Lower Midrange Module binding post labeled “Mid Frequency.”

2. Locate the cable marked “Tweeter.” Connect the cable to the

post labeled “High Frequency.”

3. Locate the cable marked “Upper Midrange.” The cable for the

upper midrange is dressed through a channel on the left side

of the wing. Loosen the bolt securing the cover and remove it.

Dress the upper mid’s cable through the channel and replace

the cover. Locate the hole located in the brace just below the

speaker terminal. Thread the cable through this hole. Connect

the cable to the module. (See the graphic on the following

page.)

Wilson Audio Specialties

Alexx Install ation and Care Guide

30

4. Connect the cable to the binding posts on the module.

Note: Please ensure that you do not invert the polarity of the umbilicals in
the Alexx. Such an inversion will produce entertaining ambient effects, but
destroys the linearity and harmonic structure of the system.

Note: If there is a need to remove the wing assembly, first remove the cable
retention cover.

Authentic Excellence™

The cable retention cover and the strategically

placed holes allow you to dress the Alexx’s ca-

bles such that they minimally interfere with the

systems enclosure.

Section 3.1—Spike Installation

Spike Assembly

• Remove the mechanical diodes and move the nut to about two

threads from the point. This will allow for greater movement

when leveling the loudspeaker system.

• Screw the spikes into the diode until the nut is against the

diode. Be careful that the nut does not turn while inserting and

threading spikes into the diode.

Note: Do not tighten these assembled spikes. You will need to unscrew
them when you level the Alexx.

• Place the set screw into the other end of the diode with the

Allen head toward the spike. This will ensure that if for any

reason you have to remove your Alexx spikes, you will be able to

withdraw the set screw safely using the supplied Allen wrench.

Screw the set screw into the diode until it meets the spike.

• Place the assemblies out of the traffic pattern until they are

needed during the installation.

weigh over 450 LBS and may seriously injure someone if tipped over.

• 8 sets of assembled spikes

• The Wilson Audio Jack

• The jack socket wrench

• Swivel caster wrench

Installation Procedure

1. Slide the Wilson Audio Jack under the front of the Alexx,

centered between the casters, so that the jack’s lift bolt is

exposed. Place the lift plate so it is positioned about an inch

behind the front facade of the Alexx woofer enclosure.

Note: An assistant should stand to the rear of the Alexx to steady it.

2. Attach the wrench to the lift bolt and begin to slowly raise the

front of the Alexx by turning the bolt clockwise.

3. After the front of the Alexx is high enough (you will need

approximately one and a half inches of clearance beneath the

caster), use the swivel caster wrench to loosen the casters.

Remove the casters.

4. Insert and screw-in the finished spike assembly. Hand tighten

only!

Wilson Audio Specialties

Alexx Install ation and Care Guide

36

Note: Be very careful not to cross-thread the spikes. The base of the Alexx
is made of “X” material and can be cross threaded if installed on an angle.

5. With one person stabilizing the Alexx, lower the Alexx by turn-

ing the jack wrench counterclockwise. Note that the Alexx will

now sit lower in the front as the spike assembly is shorter than

the caster. Use caution.

Note: It is very important, at this point, that an able assistant stabilize the
front of the Alexx until the rear spikes are attached and the unit is lowered.

6. Repeat the previous process of the caster removal/spike inser-

tion on the opposite side of the enclosure. Then continue the

process on the other channel.

Leveling the Alexx

1. It is not necessary to use the jack to level the Alexx.

2. Place a level on the top of the woofer enclosure from the rear

spikes down toward the floor. If the bubble is leaning toward

the outside of the room, you will have to lengthen one of the

outside spikes down toward the floor.

4. You may rotate the spike tips in place by using a vice-grip or

toothed pliers.

5. To find out which spike to lower, grasp the Alexx channel and

rock it back and forth. This will identify the spike that is out of

level from the other three.

Place a level on the front to back oriented axis. If it is level, then your

Alexxs are level. Using the same process as above, adjust the front or rear spikes

to achieve front to back level.

Section 3.3—Removing the Protective Film

To protect the finish of the Alexx during final manufacture, shipment,

and setup in your listening room, we have applied a removable layer of protec-

tive film over the finish. We recommend that this film be left in place until the

speakers are in their final location in your listening room. Once you have deter-

mined their final position, remove the film by following this procedure:

1. Ensure the speaker surface is room temperature before remov-

ing the protective film.

Note: Removing the protective film when the speaker surface is cold can
damage the paint surface.

Wilson Audio Specialties

Alexx Install ation and Care Guide

38

2. Slowly remove the film from the top down, large sections at a

time, gently pulling the film downward and outward.

Note: Tearing the film aggressively can damage the paint.

3. Take care in removing the protective film near edges and cor-

ners to prevent paint damage in these areas.

4. The protective film should not be left on the painted surface

for extended periods of time nor exposed to heat sources and

direct sunlight.

Section 3.4—Resistors

By removing the small glass cover on the upper bevel on the rear of the

woofer module of your Alexx, you may gain access to the resistor plate. These

resistors serve several functions.

Note: Only Wilson Audio replacement resistors should be used in your
Alexx. Changing the value or brand of resistor will have a deleterious affect
on the sonic performance of your loudspeakers and will void your Wilson

Audio Warranty.

Midrange and Tweeter Resistors

There are two separate midrange level resistors. The upper mid (the 5.75”)

Authentic Excellence™

S e c t i o n 3 . 4 — r e S i S t o r S

39

consists of a 0.75 ohms (2 X 1.5Ω in parallel), and the lower mid, which consists

of 1.2 ohm (2 X 2.4Ω in parallel). The tweeter level consists of a 2.1 ohms (2 X

4.2Ω in parallel) resistor assembly. Resistors provide precise level matching for

the midrange and tweeter drivers correspondingly. The resistors also act as a

ultra-high-quality fuse which opens before a driver can be damaged by excess

power.

Woofer Damping Resistor

There is a 23.4Ω (ohm) barrel resistor barrel resistor for woofer level.

This resistor is pre-installed in the base of the Bass Module and should not be

changed by the end user.

Resistor Fine Tuning

In rare instances for some installations, it is desirable to alter the level of

the tweeter to overcome tonal balance problems. If there is a need to increase

the level of the tweeter by 1dB, a 1.1 ohms resistor should be used (2 X 2.1Ω in

parallel). If a decrease in tweeter level is desired, a 3.1 ohms resistor will de-

crease the level by 1dB (2 X 6.3Ω in parallel).

Note: These specialized resistors can be ordered from you authorized Wil-

son dealer. Only use Wilson replacement resistors in your Alexx.

Section 3.6—Adjusting the Alexx’s XLF port

Choosing a Port Configuration:

Based on the measured bass response of the two different port config-

urations, our experience suggests the following configurations as a starting

point: For inherently lossy and lean rooms, which are thus in need of additional

deep bass extension, the rear firing port configuration is recommended as a

starting place for your room. If mid to upper bass is lean in your installation, the

forward firing port configuration is probably ideal.

If your installation requires the Alexx to be installed close to the rear wall

behind the speakers, start by installing the port in its front-firing configuration

first so as to avoid potential bass overload in your room. However, if another

loudspeaker has already proven to be too lean in this same location, start with

the Alexx’s port in the rear firing configuration.

In systems where the Alexx is replacing a MAXX, Alexia or other rear-firing

bass port system, it is generally recommended that the rear-firing port configu-

ration be initially installed.

Because there are a vast number of acoustical environments into which

the Alexx is installed, it is impossible to give absolute instructions for every

given room. Each Alexx should be evaluated in its environment, and a determi-

nation made from there.

Warning: The bass performance of the Alexx will be severely compromised
if the port is not installed in one of its two locations.

Reversing the Port Plug:

The Alexx ships with the port plug installed in the front of the woofer

enclosure for a rear-firing port configuration. To reverse the plug, do the follow-

ing.

1. Locate the Allen handle and the 1/8” Allen tip from the tool kit.

Install the tip into the handle.

2. Remove the aluminum port cover plate installed over the plug.

The port cover is secured by gaskets and pins that keep the

plate secure—no tools are required to remove the plate.

3. To remove the port plug, unbolt the six 10-32x1” button head

Allen screws and washers.

4. Re-thread one of the bolts to use as a handle to pull the plug

from the port. The plug fits tight in the port as result of an air-

tight gasket.

5. Remove the decorative port ring from the rear port.

6. Install the port plug into the rear port.

7. Install the port cover plate over the plug.

8. Install the decorative port ring into the now active front port.

56

charge for parts or labor, which service or repair, at the Dealer’s option, shall

take place either at the location where the product is installed or at the Dealer’s

place of business; or (2) if purchaser has timely sought service or repair and the
