Wilson Audio WATCH Center Series 3 - Manual (Page 27)

Note: The custom mounting bracket should be designed to hold 3 times the weight of the
Center channel (77 lbs). This gives and acceptable safety factor of 3.
9. Turn to Section 4.8 for final assembly instructions.
Section 4.8—Center Channel Final Setup
The final setup work needed before fine tuning and other speaker setup is performed
as follows:
• Set the Propagation Delay Correction on the tweeter assembly (see Section
10).
• Connect the speaker cables from the amplifier.
The propagation delay correction is one of the most important elements of the setup.
There are two methods for setting the PDC: one for floor and stand mounted Center chan-
nel and one for ceiling or any other custom location.
Stand or Floor Mounted Center Channel
1. Find your measured listening distance and ear height.
2. In Section 10, locate the table that corresponds to your Center channel loca-
tion and front spike combination (i.e. floor mounted Center channel with a
spike, nut, diode, and one spacer).
Note: There is a unique PDC setting for each Center channel location and front spike
combination. Be sure you are reading from the correct table.
3. Read from the table the required offset (see Section 10).
4. Using a 3/16” Allen wrench, loosen the 1/4-20 socket head on tweeter as-
sembly (see Figure 16 below).
5. Slide the tweeter until the indicator line on lock down bolt washer is aligned
Note: the material used for the bottom of the Center channel Wilson’s proprietary high
density composite X-material. While very hard, X-material is easily cross threaded when
installing the spikes. Be careful that the spike thread is engaging properly into the bot-
tom.
5. Screw the 3/8-16 nut and lock washer onto the setscrew from the inside of
the enclosure (see Figure 14).
6. Tighten until snug using the open-ended wrench.
7. Replace the midrange drivers.
8. While two people hold the speaker up to the mounting bracket, a third per-
son bolts the speaker to the ceiling. Use two 3/8-16 nuts on each threaded
rod. This will lock the nuts into place.
