    Wilson Audio. That’s why, in the past decade, so many blockbuster hits have been mixed, composed, or recorded using Wilson Audio loudspeakers.

  • Page 10: Applications

    Applications One of Wilson Audio’s most important criteria in speaker development is that a speaker meets the accuracy and dynamic demands of studio monitoring, analytical hardware and software evaluation, and of course, critical music and theater sound- track listening.

  • Page 11: Adhesives

    W a t c h D o g I n t r o d u c t i o n - c o n t i n u e d Adhesives The engineers at Wilson have performed extensive research on the adhesives used to construct our enclosures.

    SLAMM systems and later applied to the rest of the Wilson Line. PDC allows for opti- mal tuning of a loudspeaker for various listening distances and heights and gives lis- teners much greater control over their sound. The WATCH Center was designed from the ground up as a center channel. It is not merely a standard speaker that was tipped onto its side.

  • Page 13: Conclusion

    Wilson Audio. The WATCH Dog combines Olympian structural, design, and finish considerations with superior sonic quality. It is this approach that distinguishes Wilson Audio products. As a part of a truly high-end multi-channel system, or in a music system, the WATCH products offer unparalleled performance, quality of build, and longevity.

    I n Yo u r R o o m Note: The following section presents conceptual and practical information on room acoustics. These concepts for two-channel audio become even more important when dealing with multi-channel audio or home theater. The presence of two or more speakers in a room only increases the amount of setup difficul- ties and speaker interactions.

    interrupted by curtains or drapes. Slap echo can be controlled entirely by the applica- tion of absorptive materials to hard surfaces, such as: • Sonex • Airduct board • Cork panels • Large ceiling to floor drapes • Carpeting to wall surfaces In many domestic listening environments, heavy stuffed furnishings are the pri- mary structural control to slap echo.

    I n Yo u r R o o m - C o n t i n u e d • Sound staging - low frequency component of image shifted Standing waves are more difficult to correct than slap echo because they tend to occur at lower frequencies, whose wave lengths are long enough to be ineffectively controlled by absorbent materials such as Sonex.

    WATCH System can fill most rooms with beautiful sound. However, we want to ensure that you enjoy the benefits of the group delay adjustment features that are built into all Wilson Audio products. Speaker Placement vs. Listening Position - Main Speakers The location of your listening position is as important as the careful setup placement of your speakers in your room.

  • Page 31: Center Channel

    Center channel phase delay correction will be made via the sliding tweeter module. Wilson recommends that the Center channel be positioned as centrally between the Left and Right speakers as possible. Using the Wilson Audio Setup Procedure, experiment with the fore to aft placement of the center channel. This process will help you find the location that offers the smoothest left, right and center channel integra- tion.

  • Page 32: Speaker Orientation

    Surround Channel Wilson Audio has done everything possible to eliminate the boundary interac- tions caused by mounting a speaker onto the wall. The mounting bracket allows for significant improvements in detail, speed, and clarity. The surround channels will per- form well in almost any location in which they are placed.

    Panel to additionally limit upper bass range. This is particularly important and useful when the WATCH Dog is placed in the corner. Since all Wilson Audio Speakers are phase and time coherent, it is very important to time align the WATCH Dog in the room using the Phase Control on the Control Panel.

  • Page 34: Section 4.3 - Initial Setup Summary

    it is best to position the WATCH Dog behind the plane of the main speakers. Placement in front of the main loudspeakers, or behind the listener, can potentially compromise the phase accuracy in two-channel music systems. This will result in a less coherent presentation of the spatial, dynamic, and tonal information.

    configured more successfully without the use of the High Pass Filter. There is a normal bass roll-off that occurs naturally in your listening room. This effect acts like a six dB per octave low pass filter and rolls off the bass from your main speakers. By carefully using the WATCH Dog’s Low Pass filter controls, along with the Bass Equalization and Phase controls (discussed in Section 6), you can successfully integrate the main loud- speakers in your system with the WATCH Dog without the use of the High Pass Filter.

    C o n t r o l P a n e l S e t u p - C o n t i n u e d Initial placement of the L & R speakers If both the WATCH Dog and the main speakers are new to the system, we rec- ommend that the main speaker positions be carefully optimized for overall sound qual- ity before introducing the subwoofer.
  • Page 52 3. If you have either a spectrum analyzer or a sound pressure level (SPL) meter, you should measure and document the in-room response of your L & R loudspeakers, running full-range, without subwoofer contribution. This will give you a baseline measurement. While you can measure each channel individually, it is more expedient to measure both simultaneously using the (Mono) test signals.

    All audio equipment will sound its best after the components have been bro- ken-in for some period of use. Wilson Audio breaks in the woofer of your WATCH Dog for a 12 hour period. All drivers are then tested, calibrated, and matched for their acoustical properties.
