Placement
Plan your speaker placement carefully. Make certain
that electrical, plumbing and any other services will not
interfere within the walls or ceiling where you plan to
place your speakers. The AS GRP8 speakers can be
mounted in the walls or in the ceiling. The speakers
should be located so that they provide even coverage at
your listening position. For the Left and Right speakers
the distance between the speakers should not be
greater than the distance from the speakers to the
listening position. The Rear Surround in-ceiling
speakers should be placed to either side or slightly
behind the listening position. (see fig. 1) If the room’s
dimensions or furniture placement prevent adhering to
this requirement, the tweeters in the GRP8 speakers
can be swiveled to aim them at the desired listening
position. Speaker height on in-wall speakers should be
maintained at ear level or just slightly above. Again,
the tweeters may be aimed into the listening area.
New Construction
If you are installing your speakers in new construction
before the finished walls and ceilings go up, Audio-
Source offers Pre-Construction Brackets, Part #NCB-
W8 and NCB-C8 that provides a stable frame that can

In most modern buildings the wall studs are positioned
on 16” centers, providing a space between the studs of
approximately 14

”. The AS8S requires a mounting
hole 8

mounting hole 9

“ in diameter. Additionally, you
should allow an extra
3/4
” in all directions around the
opening and behind the wall surface to provide room for
the doglegs to swing into position and secure the frame
to the wall surface.
Use a stud finder to locate the vertical studs behind the
wall surface. Also, you should now check for
obstructions like cross bracing above and below the
desired speaker location.

be fastened to the wall studs and ceiling joists on 16” or
24” centers. This allows the sheetrock or other wall
covering to be installed and clearly leave the opening
for the GRP6 speakers. The brackets are sold
separately in sets.
After selection of the mounting location, mark the hole to
be cut out. A template is provided in the speaker box.
Locate and align the template, then mark the opening
with pencil on the wall or ceiling surface. If you are
unsure whether there are obstructions behind the ceiling
surface where the speakers are to be mounted cut a
small hole in the center of your marked mounting
location. Holding your drywall saw at a 45 degree angle
(See Fig. 2) cut a square hole that you can use to locate
any obstructions, should they exist.
