Step 1.
Install the upper bracket to the midrange horn as
shown with two 1/4" x 7/8" machine screws and
flatwashers. With the horn right side up, the
protruding flange with the center hole of the upper
bracket will be on the left when facing the cabinet
back.
Step 2.
Position the separated plywood midrange horn
base with the t-nut side down. Install the lower
bracket to the separate plywood horn base as
shown with two 1/4" x 7/8" machine screws and
flatwashers.
Step 3.
Position the midrange horn upside down on a flat
surface. Align the half of the hinge with the center
hole with the center hole of the midrange horn’s
front edge. Make sure that the hinge pivot pin is
toward the front. Install three #8 machine screws
into the three t-nuts in the horn.
Step 4. Align the front edge of the plywood midrange horn
base flush with the pivot of the remaining hinge
half. The bracket installed in Step 2 above, needs
to be on the same side of the plywood base as the
hinge. Install four #8 x 3/4" wood screws through
the hinge into the plywood base.
Step 5.
Position the midrange horn and plywood base
assembly right side up on top of the low frequency
speaker cabinet. Align the four pivot holes and slots
in the base with those in the speaker cabinet.
Loosely install four 1/4" x 1 1/4" machine bolts and
flatwashers through the base into the low frequency
cabinet.
Step 6.
Loosely assemble the two extension arms by
inserting two 1/4" x 7/8" machine screws,
flatwasher, lockwasher, and nut.
Step 7.
Loosely assemble the extension arm assembly to
the upper bracket with a 1/4" x 7/8" machine screw,
flatwasher, lockwasher, and nut.
Step 8.
Similarly, assembly the bottom end of the extension
arm assembly to the lower bracket with a 1/4" x
7/8" machine screw, flatwasher, lockwasher, and
nut.
Step 9.
On a separate surface, install the CH-7 horn into
the front of the high frequency horn baffle with six
1/4" Phillips head screws and flatwashers.
