at a time.

Check Diaphragm spacing to ensure 36” [914 mm]
between rear faces of consecutive Diaphragms as
shown in Fender Panel assembly drawing (Figure

Step 7
Once proper spacing has been achieved, tighten
the Mushroom Washer Assembly (small hex) nut
until it reaches the end of the screw threads.
Assemble the remaining Diaphragms and Fender
Panels following the same procedure.
Tighten rail nuts (large hex) at the front of the
Fender Panels. Ensure the rail bolt shoulder is
seated within the Fender Panel slot.
