Assembly Instructions
Step one:
Insert one large hex bolt through one inner mounting
boss, and position on one of the two yoke mounting
holes on the inside of the horn bell. The inner mounting
boss has a hex-shaped indentation for the bolt head
to rest in. Be sure to place the boss so that the arrow
is pointing toward the mouth or large opening of the
horn. You may find it helpful to put a piece of tape over
the bolt head and boss to hold them in position while
repeating the procedure on the other side.
Step two:
With both inner bosses and hex bolts in place, posi-
tion one outside mounting boss on a protruding hex
bolt, again taking care to align the boss with the arrows
pointing to the front of the horn. Hold the inner boss
and bolt with one hand, and place one rubber washer
over the boss.
Step three:
While still holding the hardware from the inside, slip one
end of the U-shaped mounting bracket over the bolt,
capturing the rubber washer. Place one flat washer, one
split ring lockwasher, and one hex nut over the bolt and
thread loosely to hold in place
Step four:
Gently spread the mounting bracket to attach to the
opposite mounting boss, ensuring that the bolt passes
through, and that a second rubber washer is captured
between the bracket and the mounting boss. Place a
flat washer, a lockwasher, and a hex nut on the bolt and
fasten finger-tight.
Step five:
Align the three threaded mounting holes on the re-en-
trant tube with the holes on the back or small end of the
main horn assembly. Start a small bolt and washer into
each hole, and then tighten with a wrench.
Step six:
Mount the compression driver of your choice. Tighten
the two large bolts on the mounting bracket, taking care
to not overtighten them.
2 large flat washers
