LIGNMENT
Pulse alignment accuracy of the X-1/Grand SLAMM has been established and verified at Wilson
Audio’s R&D laboratory. The graphs and charts used in this section are a result of this testing.

ETUP
The X-1/Grand SLAMM system allows for different listening distances (away from the speakers)
and listening ear heights (measured distances from the floor up to your ear), see Figure 20 below. For each
distance/ear height combination there is a unique alignment geometry.
To make correct in home set up of the X-1/Grand SLAMM possible without test equipment, Wilson
Audio has measured the correct geometric time domain alignment for different distance/ear height combina-
tions. This information is provided in Appendix A. 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. Section 4.3
gives an example of this alignment procedure.
