Section 1.1—Room Acoustics

You are surely excited about setting up Alexia™ loudspeakers and doing some

listening, but before you begin, we would like to discuss some of the important room

acoustical information that will help you set up your loudspeakers properly.

Final Listening Room Setup (Voicing)

For a speaker system its size, the Alexia is unmatched in its ability to reproduce

the musical event. It is truly state of the art. However, room acoustics and boundary in-

teractions affect the sound of a loudspeaker to such a large degree that poor setup can

seriously degrade your enjoyment of even the finest loudspeaker.

Therefore, we offer the following section, which will present some guidelines on

room acoustics and their interactions with loudspeakers. While we will also outline

some detailed suggestions on the setup of the Alexia, we strongly suggest that you have

your local Wilson Audio dealer perform the final speaker “voicing” with you. Wilson

dealers are specially trained in setting up Wilson loudspeakers and will ensure that you

realize the full value of your purchase.

Section 1.2—Wilson Audio Setup Procedure (WASP)

Zone of Neutrality

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 lis-

tening environment:

Al e x i A O w n e r ’sM AnuAl

1. Stand against the wall BEHIND the location where you intend to position

Alexia. Speaking in a moderately loud voice and at a constant volume,

project your voice out into 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 another 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 cor-

rect 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, the zone in

most rooms 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, usu-

ally 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 in-

teracting with the opposite wall. At the point where you begin to hear the

reflected sound of your voice, you have reached the inner 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 be-

tween 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
