Installation
The HT-3 Surround Loudspeaker System may be installed
with one person, however two persons will add to the safe
handling during installation. Follow the instructions below
for unpacking and assembly. It is recommended that the
Professionals at your McIntosh Dealer, who are skilled in
all aspects of installation and operation, install the HT-3
Loudspeaker System and any associated audio equipment.
The HT-3 Surround Loudspeaker System is a mirror-im-
age, dipole design with the pair of 2 way systems con-
nected out of phase with each other. The pair facing for-
ward toward the viewing screen must be in phase with the
front Loudspeakers. To insure correct phasing, the loud-
speakers are marked as Left and Right, along with a direc-
tional arrow which must be pointing toward the screen and
the front loudspeakers.
HT-3 Surface Mount
1. Remove the front grille from the HT-3 by gently pull-
ing it forward. Refer to figure 3.
2. Position the HT-3 on the wall where you wish to
mount it. Us-
ing the Loud-
speaker as-
sembly as a
template,
mark on the
wall the loca-
tions for the
four mount-
ing screws.
3. Install using
four suitable
wall mount-
ing fasteners
and insert the
screws par-
tially so they extend out far enough to clear the thick-
ness of the HT-3 back panel.
Note: The fasteners must have a total of 20 pounds or
more of load capacity.
4. Position the HT-3 over the screws and slide it down so
the screws fit in the mounting slots. Tighten the
screws.
5. Replace the HT-3 grille by gently pressing it inward
where the foam gaskets will hold it in place. Follow
the same procedure for both the Left and Right HT-3
systems.
Note: If the HT-3 is ceiling mounted, additional fasteners
are need to secure the grille to the Loudspeaker.
HT-3 Flush Mount
1. Determine the location where you wish the HT-3
Loudspeakers to be installed in the wall. Refer to fig-
ure 4.
2. Cut a 14-1/4 inch square hole centered in the desired
position.
The lo-
cation
should
be cen-
tered be-
tween
the wall
studs
since the
HT-3
will take
most of
the
space,
with just a small clearance on each side.
Note: There must be no obstructions within 1 inch of the
cutout on the top and bottom. This is to provide
clearance for the slide fasteners to fit behind the
wall panel. The area behind the HT-3 must be free
of any wires, cables or other obstructions since the
speaker depth is 3-1/2 inches, and may fill the
entire space between the walls.
3. Remove the front trim frame and grille.
4. Proceed to page 8 for connection information and then
perform step 5 below.
5. Carefully slide the HT-3 into the wall cutout.
Note: If the wall studs are 2 x 6, be careful to hold the
speaker in place so it does not fall behind the wall
prior to securing the trim frame.
6. Loosen the screws on the four slide fasteners. Slide the
fasteners up and down so they fit behind the wall to
hold the HT-3 in place and then tighten the screws.
7. Place the trim frame in position over the HT-3 and se-
cure it to the loudspeaker system using the supplied
screws. Use the mounting holes at the top and bottom
edges of the frame
Note: The holes on the sides of the frame are not used.
8. Carefully press the grille into the trim frame, where
the foam gasket will hold in position.
