height, it will need to be raised more in the back so the speaker is firing down toward the

listener.

After determining the required rotation for the Center channel, Sections 4.3-4.6, as-

semble the spikes as follows:

Assembly

1. Back out the setscrews on the bottom of the enclosure to the desired height

(see Figure 7) . 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 halfway into the

diode.

4. Screw the spike (with nut) all the way in until it just touches the bolt. Do not

tighten the nut at this time.

5. Repeat steps 1—4 with the other spikes.

Section 4.3—Measured Listening Position

Room Setup

The Center channel allows for different listening distances (away from the speakers)

and listening ear heights (measured distances from the floor up to your ear); see Figure 8

below. Propagation Delay Correction accuracy of the Center channel has been established

and verified at Wilson Audio’s R&D laboratory. The tables outlining the settings for adjust-

ments are in Section 10 of this owner’s manual. The correction tables used in this section

are a result of this testing. For each distance/ear height combination there is a unique

alignment geometry. To make correct in-home setup of the Center channel possible with-

out test equipment, Wilson Audio has measured the correct geometric PDC (phase delay

correction) alignment for different distance/ear height combinations. By measuring the ear

height and the distance from the speaker to the listening position, you will be able to align

the system for your listening position.
