S E C T I O N 1 - I N T RO D U C T I O N S e c t i o n 1 - W AT C H I n t r o d u c t i o n If your passion is home theater, and you have sought the full sensory experience created as your eyes absorb the vision and your skin awakens to the power of the sound, Wilson Audio has your answer. Introducing WATCH.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L speakers. The Watch system is designed to integrate with the Sophia, WATT/Puppy, MAXX and, in many instances, the Alexandria. Using structural enclosure, speaker driver, and geometric time alignment technologies developed for the WATT/Puppy, MAXX, and the X-1 Grand SLAMM, the WATCH system is truly the thoroughbred of its class and is well-suited to carry on the heritage of Wilson Audio speakers.
S E C T I O N 1 - I N T RO D U C T I O N tions of a high-performance home theater system. This was a difficult task because of the many interactions that occur in a home theater environment. Because the WATCH system was designed in-house and voiced with a variety of Wilson speakers, you can be sure that the driver blend will be excellent whether your system includes Sophias or Alexandrias.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L The WATCH Center Channel was designed from the ground up as a center channel. It is not merely a standard speaker that was tipped onto its side. The Center Channel was voiced and optimized to truly represent dialogue for movies as well as music and vocals when used in a multi-channel audio setup. Of course, WATCH Center lives up to Wilson high standards of cutting edge design, superior build quality, and stunning sonic performance.

The Surround can also be rotated towards the listening position, offering improved integration with the front speakers and better imaging. WATCH Dog The WATCH Dog has been designed to integrate well with any of the Wilson Audio loudspeakers you chose for your multi-channel system. The bass is clean, powerful, and uncolored.

S E C T I O N 2 - I N YO U R RO O M Note: The following section contains general information on room acoustics and loudspeaker/room interaction. The concepts outlined below are equally relevant when dealing with multi-channel audio or home theater. The careful application of these concepts, as you evaluate the acoustical characteristics of your own room configuration, will allow you to optimize the performance of your WATCH Center Channel.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L diffuse. Slap echo is a common acoustical problem in the typical domestic listening room because most of these rooms have walls of a hard, reflective nature, usually being only occasionally interrupted by curtains or furniture.
S E C T I O N 2 - I N YO U R RO O M ever, diffusers can rob the system of bass richness and add significant midrange colorations. A combination of absorptive and diffusive treatments is usually the best approach. Standing Waves Another type of reflection phenomenon is standing waves.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L discreet locations in the room. A room generating severe standing waves will tend to make a loudspeaker sound one way when placed in one location and entirely different when placed in another.
S E C T I O N 2 - I N YO U R RO O M In general, placement of the speaker in a corner will excite the maximal number of standing waves in a room and is to be avoided for most direct radiator, full-range loudspeaker systems.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L F I G U R E 4 - C O M B F I LT E R E F F E C T • Added roughness to the sound • Reduction of harmonic richness • Smearing of lateral sound stage image focus and placement Comb filter effects are often caused by side wall reflections.
S E C T I O N 2 - I N YO U R RO O M tion occurs. Section 2.1 - Resonance Resonance in listening rooms is generally caused by two sources: • The structures within the listening room • The volume of the air itself in the listening room Structural Resonance Structural resonances are familiar to most people as buzzes and rattles, but this type of resonance usually only occurs at extremely high volume levels and is usually masked by the music.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L ers of sheet rock or book shelves to flimsy walls, however, there is little that can be done to eliminate wall resonances. Air Volume Resonance The physical dimensions and volume of air in a room will also support standing wave modes and resonances at a frequencies determined by the size of the room. Larger rooms will resonate at a lower frequency and have more complex (better) modal distributions than will smaller rooms.

S E C T I O N 3 - I N I T I A L S E T U P I N F O R M AT I O N Section 3 - Inital System Setup We strongly recommend that you have a Wilson Sudio dealer come to your home and help you with the set up of the WATCH System. they have been trained on setting up our systems to provide you with the most satisfying results. However, if you choose to set up the system yourself, we have provided some instruction that will allow you to achieve very good performance from the WATCH System.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L Room Shapes Standing waves are pressure waves propagated by the interaction of sound and opposing parallel walls. This interaction creates patterns of low and high acoustical pressure zones that accentuate and attenuate particular frequencies. Those frequencies are dependent on room size and dimension. There are three basic shapes for most rooms: square, rectangular, and Lshaped (see Figure 5).
S E C T I O N 3 - I N I T I A L S E T U P I N F O R M AT I O N FIGURE 5 - POSSIBLE PLACEMENT RO O M S H A P E S WITHIN VA R I O U S 35
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L In many cases, L-shaped rooms offer the best environment for speaker setup. Ideally, speakers should be set up along the primary (longest) leg of the room. They should fire from the end of the leg (short wall) toward the L, or they should be along the longest wall. In this way, both speakers are firing the same distance to the back wall. The asymmetry of the walls in L-shaped rooms resists the buildup of standing waves (see Figure 5 ).
S E C T I O N 3 - I N I T I A L S E T U P I N F O R M AT I O N on the floor to mark this location. You will now be entering the outer edge of the “Zone of Neutrality.” Although this can vary from room to room, this is usually between 2 and 3 1/2 feet from the rear wall. 4. Continue to walk slowly away from the wall. After some distance, usually one to two feet, you will hear the beginning of a new artifact - the interaction with the opposite wall.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L Section 3.1 - Choosing a Listening Position Decide where you want your listening position to be. Please remember that your WATCH System can fill most rooms with beautiful sound. However, for the PDC advantage, we want to ensure that you get all the benefits possible with the propagation delay adjustment features that are built into this design. Listening positions that are too close to a boundary will deteriorate the overall system performance.
S E C T I O N 3 - I N I T I A L S E T U P I N F O R M AT I O N Speaker Orientation Speaker placement and orientation are two of the most important considerations in obtaining superior sound. The first thing you need to do is minimize the influence of the side walls on the sound of your system. Speakers placed too close to the side walls will suffer from a strong primary reflection.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L configurations are possible: • Set on the floor with speaker angled up towards the listener. • Mounted on stand with no rotation. • Mounted on stand with longer spikes in the front of stand and shorter spikes in the back allowing the stand and speaker to be rotated up toward the listener. • Mounted above TV on a custom made bracket. • Mounted upside down on ceiling with speaker angled down towardsthe listener.
S E C T I O N 3 - I N I T I A L S E T U P I N F O R M AT I O N grates best when placed centered between the left and right speaker and either aligned horizontally with the front inner edge of the left and right speakers or slightly behind the front inner edge. You will want to experiment with the center channel distances and find the location that offers the smoothest left, right, and WATCH Center Channel integration. We will step you through this process in Section 5.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L least amount of reflections or standing waves. Be sure to listen for room modes and frequency response peaks or dips. WATCH Dog The WATCH Dog will perform very well in any location in the room. In general, the closer you place theWATCH Dog to a wall or corner, the greater the augmentation of the bass. However, the increase in bass comes at a cost of perceived speed, dynamics, and bass clarity.
S E C T I O N 3 - I N I T I A L S E T U P I N F O R M AT I O N Be sure to place the WATCH Center Channel even with or slightly behind the front inner edge of the left and right speakers. The WATCH Surround channel should be mounted on the wall in a location that has the least amount of reflections and standing waves. The location should have a natural sound if you stand next to it and project your voice into the room. The WATCH Dog has a great degree of flexibility in its placement.

S E C T I O N 4 - WAT C H C E N T E R C H A N N E L S E T U P Note: Before setting up the WATCH Center Channel study carefully the previous sections on room acoustics and initial setup information. They provide valuable information on determining the ideal room locations for your speakers.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L Setup Procedure 1. Gently slide the WATCH Center Channel out of the crate. Remove the plastic outer bag by tilting the Center channel over on one side and opening the bag at the base of the Center channel. Remove the bag. Note: Do not cut the bag off of the Center channel. You may mark the cabinet or damage a driving element. Additionally, you will need this bag, if you need to repackage the Center channel.

Insert either the short or the long threaded bolt, depending on the desired height (see Figure 6) as far as it will go into the hole in the bottom of the Center channel. Make sure the Allen key end is accessible. 2. If required, place the corresponding number of spacer discs over the bolt. 3. Screw the acoustical diode onto the bolt until it is roughly half way into the diode. 4.

Nevertheless, the WATCH Center Channel will certainly out-perform any other center channel placed in a given location. Placing the Center channel in any location other than on the Wilson Audio WATCH Center stand will require the WATCH Center channel to be rotated toward the listening position.

This is done by using a taller spike in the front than in the back of the speaker (see Figure 8).
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L 1. Using provided 3/16” Allen wrench, remove the 4 setscrews from the bottom of the Center channel. Keep these as they are the setscrews needed to assemble your spikes. 2. Turn to Section 9, page 107. Locate your listening position on the table. 3. Assemble the front spikes with the listed diode/spacer combination. 4. Install the spikes as shown in Figure 8 above.

Turn to section 4.6 for final assembly instructions. Section 4.4 - Center Channel on Custom Stand or Shelf The Center Channel is a shielded speaker, and therefore, could be placed directly on top of a television. However, this is not recommended due to the weight of the speaker. In time, damage may occur to your television.

The requirements for this bracket are outlined at the beginning of Section 4. 5 on page 59. The speaker should be rotated so that the midrange drivers are firing just below the listening position. Once you have made and mounted the custom bracket, setup the Center channel as follows:. 1. Lay the Center Channel on its side. 2.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L Note: Be sure that the Allen key end of the set screw is facing out. 4. Carefully lift the Center channel and set the threaded setscrews into the four mounting holes located on the top of the mounted custom shelf. 5. Using the provided 3/8”-16 nut, bolt the Center channel to the mounting bracket. 6. Turn to section 4.6 for final assembly instructions.
S E C T I O N 4 - WAT C H C E N T E R C H A N N E L S E T U P Section 4.5 -Center Channel Mounted to Ceiling Note: For a floor or wall mounted Center Channel, a custom mounting bracket is required. It is important that this bracket be made as instructed so as to be strong enough to securely fasten the Center Channel to the ceiling or wall. Custom Made Mounting Bracket Requirements A ceiling mounted WATCH Center Channel will be mounted upside down (tweeter beneath the midrange drivers).

S E C T I O N 4 - WAT C H C E N T E R C H A N N E L S E T U P • A good material for the bracket is 1” square tubing. This can be easily welded together and will provide a rigid, strong support for your WATCH Center channel. • The slanted portion of the bracket will require mounting holes whose location match those on the bottom of the Center channel. The hole pattern is shown in Figure 15.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L Mounting Center Channel above Television Mounting the Center channel above a TV requires a custom made bracket. This bracket will support the weight of the Center channel and allow it to be rotated toward the listening position (see Figure 12). This rotation will significantly improve the performance of your Center channel, improving system integration, phase delay correction, and providing a correct image height.
S E C T I O N 4 - WAT C H C E N T E R C H A N N E L S E T U P tion. This can be achieved by making a bracket that is higher in the back than in the front. Because the rotation required for the WATCH Center channel depends on your listening position, speaker mount height, and listening ear height, we are unable to provide a table with all of the possible combinations.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L 3. Lay the Center Channel on its side and screw the four 3-inch setscrews one inch into the threaded holes on the bottom of the speaker. Note: Be sure that the Allen key end of the setscrews is facing out when screwing it into the enclosure. This will allow for easy installation and removal in the future. 4. Using the 5/32” T-handled Allen wrench, remove the two midrange drivers. Do not unsolder the leads (see Figure 13).
S E C T I O N 4 - WAT C H C E N T E R C H A N N E L S E T U P Section 4.6 - Center Channel Final Setup The final setup work needed before fine tuning and other speaker setup is performed as follows: • Set the Phase Delay Correction on the tweeter assembly. • Connect the speaker cables from the amplifier. Phase Delay Correction - Stand or Floor Mounted The phase delay correction is one of the most important elements of the setup.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L 4. Using a 3/16” Allen wrench, loosen the 1/4”-20 socket head on tweeter assembly (see Figure 17 below). 5. Slide the tweeter until the lock down bolt is centered above the alignment mark on the tweeter mounting bracket. 6. Retighten the socket head capscrews until snug. Note: When loosening or tightening the screws, be careful that you do not damage the painted finish.

SECTION 5 - FINAL SYSTEM TUNING AND VOICING Section 5 - Final System Tuning and Voicing This loudspeaker placement method was developed by David A. Wilson, for Wilson Audio Specialties. The purpose of this method is 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.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L • Set up of Left and Right Channels, with all other speakers disconnected. • Add the Center Channel. • Add the Surround Channels. • Add the Subwoofer. Adding one speaker at a time will allow you to easily evaluate the integration with the system and make the necessary adjustments to fine tune the setup. Section 5.
SECTION 5 - FINAL SYSTEM TUNING AND VOICING • Place your multi-channel processor into stereo mode. • Using a piece of full range music (dynamic with a lot of low frequency information) played at a moderately high level, take notes on the sound quality. Pay specific attention to upper and lower bass quality, dynamic contrasts, image height, and focus. • Move the speakers back or forward in one inch increments and then 1/2 inch increments.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L • Place a piece of tape on the floor parallel to the front edge of the speaker and again mark off 1/2 inch increments side to side. • Using only one channel/speaker at a time, you will now determine the optimum position with regard to the side walls. Note: A high quality, solo piano recording works well for this step.
SECTION 5 - FINAL SYSTEM TUNING AND VOICING tion of each of the speakers, setting speaker distances, delays, and phase rotation. These adjustments are made via internal electrical adjustments. We have found that actual geometric changes, that is, moving the speaker location and rotation, offer improved results when integrating speakers. We recommend that you follow the steps outlined below, evaluate your system performance, and then make adjustments in the processor.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L any voids in the soundstage. • Make 1/2” changes in front to back location until you find the Center channel location that offers the best integration. Image Height Check the image height. Does the dialogue of a movie have the correct height? Is it too low or too high? If needed, adjust the amount of rotation until the image height is correct. On a stand or floor mounted Center channel, raising the front spikes will raise the image height.
SECTION 5 - FINAL SYSTEM TUNING AND VOICING • Screw the spike and nut into the diode. • Screw the 3/4” setscrew into the front spike holes in the stand. • Thread the spike assembly onto the setscrew. Resetting the PDC Once the final rotation has been determined, you will need to reset the PDC. If you have raised the speaker by adding a diode or 1/2” spacer, read the PDC from the table that matches your current spike configuration in Section 9.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L Note: If you lowered the speaker, then the tweeter will slide back 1/2 of the lowered distance. Every system has a unique time and phase character, which can effect the PDC accuracy. Because of this, you may find that sliding the tweeter forward or backwards a few positions increases the clarity and correctness of your Center channel.
SECTION 5 - FINAL SYSTEM TUNING AND VOICING Integrating the WATCH Dog The WATCH Dog will perform well in almost any location in the room. In general, the closer you place the WATCH Dog to a wall or corner, the greater the augmentation of the bass. However, the increase in bass comes at a cost of perceived speed, dynamics, and bass clarity. We recommend that you experiment with the placement of the subwoofer to find a balance of the above mentioned items with which you are satisfied.

SECTION 6 - CARE OF THE WAT C H C E N T E R C H A N N E L Section 6.0 - Care of the Finish The WATCH Center loudspeaker is hand painted with WilsonGloss™ paint and hand polished to a high luster. While the finish seems quite dry to the touch, final curing and complete hardening takes place over a period of several weeks.
WAT C H C E N T E R C H A N N E L O W N E R ’ S M A N U A L Dusting the WATCH Center It is important that the delicate paint finish of the WATCH Center be dusted carefully with the dust cloth, which has been provided. We recommend that the following procedure be observed when dusting the speakers: • Blow off all loose dust. • Using the special dust cloth as a brush, gently whisk off any remaining loose dust. • Shake out the dust cloth.
SECTION 6 - CARE OF THE WAT C H C E N T E R C H A N N E L Section 6.1 - Care of the Grilles Periodically, you will want to clean the Center’s grilles. This is best done by using the round brush attachment on a vacuum cleaner hose. Gently vacuum the front surface of the grille. Be careful not to apply too much pressure. Do not use a hard plastic attachment against the grille. The grille cloth is stretched tightly over the grille frame.

Section 6.3 - Enclosure Technology Wilson Audio has conducted many hours of research on the impact of materials on speaker enclosure performance. Through this effort, Wilson pioneered the use of non-resonant materials, first with the use of mineral filled acrylic in the WATT, and continuing with the further development of proprietary materials for X-1 Grand SLAMM and MAXX.
SECTION 6 - CARE OF THE WAT C H C E N T E R C H A N N E L permanently bond our speaker enclosures. This is often an overlooked element crucial to the proper performance of a loudspeaker. Correct modulus of elasticity, coefficient of thermal expansion, and natural frequency response are just a few of the important elements of adhesives.
