Please read this Installation Manual to ensure the

Preparing for your Installation
Gather the necessary tools for your installation.
You will need the following tools:
1) A Keyhole or Drywall Saw
2) A Phillips Screwdriver
3) Masking Tape
4) A Pencil
5) A Tape Measure
6) A Stud Finder (recommended)
7) Your AC Series speakers
Placement
Plan your speaker placement carefully. Make certain
that electrical, plumbing and any other services will not
interfere within the ceiling where you plan to install your
speakers. The AC Series speakers can be mounted in
walls, but are typically used in ceilings. The speakers
should be located so that they provide even coverage
at your listening position. The distance between the
speakers should not be greater than the distance from
the speakers to the listening position (See Figure 1).

Use a stud finder to locate the joists behind the ceiling
surface. Also, you should now check for obstructions
like cross bracing in front of and behind the desired
speaker location.

Existing Construction
In most modern buildings ceiling joists are positioned
on 16” centers, providing a space between the joists of
approximately 14 3/8”. The specifications chart shows
the appropriate cut out sizes (p. 4). Additionally, you
should allow an extra 3/4” in all directions behind the
ceiling surface to allow room for the screw clamps that
mount the speaker to the ceiling to swing into position.
