For this example the word “Tic” will be defined as one of the smaller marks between the numbered
marks on the timing blades (see Figure 21).

:
• Right channel listening distance is 12 feet.
• Left channel listening distance is 12 feet 3 inches.
• Ear height is 40 inches above the floor.
The proper time alignment for the right channel begins by locating the 40 inch ear height line on Fig-
ure 22 (next page), which is the geometric graph for the lower mid-range module. The ear height is shown
on the right side of the page.
At the listening position of 12 feet the geometric alignment position for the center of the 5/16”- 18
X 1 ¾” bolt reads 6 plus 1 tics. The high frequency module data are given in Appendix A. The geometric
alignment position for this module reads 7 plus 1 tic. The upper mid-range module data are given in Appen-
dix A, the geometric alignment position for this unit reads 4 plus 2 ½ tics
For the left channel, the procedure is the same. The geometric alignment for the left channel is:
• Lower mid-range module: 6 plus 1 tic.
• High frequency module: 7 plus 1 ½ tics.
• Upper mid-range module: 4 plus 3 tics.
For this example the X-1 Grand SLAMMs system have been properly aligned for the listening posi-
tion and after final assembly will be ready for use.
