ACHERON OPERATING INSTRUCTIONS
25
3. Remove the two 3/8-16 x 1.5-inch screws at the top of
each side of the Acheron LF (four total). These screws
will be used to secure the stacking bracket to the
Acheron LF.
4. Remove the two 3/8-16 x 1.5-inch screws at the bottom
of each side of the Acheron (four total). These screws will
not be needed for installing the stacking bracket.
5. Secure the left bracket to the left side of the Acheron LF
with two of the removed screws and two of the small flat
washers (included in the Acheron stacking bracket kit).
Use the bracket’s bottom screw holes and install the
bracket so its rubber gasket faces the loudspeaker.
■ To mount the Acheron with downtilt, orient the bracket
with the large end toward the rear of the loudspeakers.
For available downtilt angles, see “Stack Mount Downtilt
Angles” on page 26.
■ To mount the Acheron with uptilt, orient the bracket with
the large end toward the front of the loudspeakers. For
available uptilt angles, see “Stack Mount Uptilt Angles”
on page 27.
6. Secure the right bracket to the right side of the
Acheron LF with the remaining two screws (previously
removed) and the remaining two small flat washers.
Install the bracket so its rubber gasket faces the loud-
speaker.
7. Secure the stacking brackets to the Acheron with the
four 3/8-16 x 1.5-inch shoulder screws and four large
1/2-inch washers (both included with the Acheron stack-
ing bracket kit). Insert the shoulder screws in the
bracket’s top slots but don’t yet tighten them completely.
TIP: If necessary, tip the Acheron slightly to
align its screw holes with the bracket holes.
8. Adjust the angle of the stacked Acheron — anywhere
between 0 and 16 degrees — by tilting the unit up or
down so the screws slide through bracket slots.
9. Tighten all four shoulder screws to secure the stacking
bracket to the Acheron.
