Section 5 – Final System Tuning and Voicing

This loudspeaker placement method was developed by David A. Wilson, for Wil-

son Audio Specialties, to find optimum loudspeaker location in any given room within

one hour. Participating in numerous audio/multi-channel/home theater shows with very

different and difficult acoustic environments necessitated this procedure. Currently,

all Wilson Audio dealers employ this setup procedure for their customers, in order to

quickly and predictably achieve the best performance from their systems (this proce-

dure can be used successfully with ANY moving coil speaker system).

Proper system calibration is the most important step in the setup of your multi-

channel/home theater system. The WATCH system offers increased resolution and over-

all system performance. This increased resolution allows you to fine tune your system,

thus increasing overall performance, more than any other system available.

Fine tuning and “voicing” generally involve only small changes in location and

rotation (or toe) of your multi-channel system. With proper calibration you will find

that changes as small as 1 inch will have an impact on the performance of your system.

The following sections step you through this fine tuning process. Sections 7.1 and 7.2

will cover a multi-channel setup. Section 7.3 will cover two-channel audio. The multi-

channel setup will be done as follows:

•

Set up of Left and Right Channels, with all other speakers disconnected.

•

Add the Center Channel

•

Add the Surround Channels

•

Add the Subwoofer
