Use the following table to help calculate the ideal starting distance from adjacent walls and the distance between
each adjacent loudspeaker. Multiplier A is for vertical and horizontal spacing. In order to cover a large area, wider
variances in coverage may be acceptable. For our example, a direct field variance of ±6.0dB is desired. That corre-
sponds to a multiplier of 3.0.
Multipliers for FreeSpace
® 6 loudspeaker spacings are shown up to ±6dB direct field coverage. This spacing yields no
more than ±3dB of reverberant field coverage, the industry standard.
Calculate the loudspeaker placement for this installation.
For placement of loudspeakers from a wall, multiply 
1/2A x H. In our example, 1.5 x 6 feet = 9 feet.
For placement of loudspeakers from each other, multiply A x H. In our example, 3 x 6 feet = 18 feet.
So in our example, the loudspeakers will be placed at the 9 foot mark from each wall. This gives an 18 foot distance
between each loudspeaker. Be aware that not all installations will lend themselves easily to the formulas but the
formulas can be a great aid in determining loudspeaker placement. Your experience and judgement will be an
invaluable asset in determining loudspeaker placement.
Note: The loudspeaker layout should be centered in the room so the distance between the loudspeakers at the edge
of the layout and the perimeter walls is fairly uniform. If necessary, shift the entire loudspeaker layout to ensure a
consistent border. DO NOT install loudspeakers less than 3
1/2 feet (1 meter) from any wall. Doing so causes a reduc-
tion in bass due to the proximity of the wall.

20,000 ft3 (570 m3 ). If the room is larger than 20,000 ft3 (570 m3), we suggest talking to a Bose® representative to determine the best
Bose system for the requirements.
†  Even coverage can be achieved with this room size. However, sound pressure will be lower.

1.3.3 Surface-mount loudspeaker placement
Determining where to place surface-mount loudspeakers is easy. Using your floor plan (which is drawn to scale),
draw 25 foot (7.5 m) spacing circles to determine loudspeaker placement.
If your floor plan
scale dimension is...
1⁄16 inch (.16 cm) 19⁄16 inch (4 cm)
1⁄8 inch  (.31 cm) 31⁄8 inch (8 cm)
1⁄4 inch  (.63 cm) 61⁄4 inch (16 cm)
Note: The surface-mount loudspeakers have a throw distance of 25 feet (8 m). For effective coverage only 80% of the
area need be covered. The spacing circles should just touch each other or overlap slightly.
Follow these simple rules when laying out the loudspeakers.
• The spacing circles can be drawn with a compass.
• Place a symbol on your floor plan identifying the location of the loudspeaker.
• Start in the corners, if possible, for maximum coverage and bass response.
• Because additions and/or cancellations occur from walls, do not space the loudspeaker equidistant from a side
wall and the ceiling. In other words, do not place the loudspeaker 3.5 feet (1 m) from the side wall and 3.5 feet
(1 m) from the ceiling.
• In a square room, place each loudspeaker slightly off center.
• The maximum height for the loudspeakers should be 12 feet (4 m) from the floor.
For technical assistance, call 1-800-994-2673 in the USA or your local Bose
® distributor.

1.4 Ceiling types
Check the ceiling construction before beginning installation. Ceiling type, thickness, and strength determine the
installation and connection methods for the loudspeakers. Ceiling type also dictates whether to use support rails. If in
doubt about these choices, consult a building trade professional, architect, or licensed professional engineer.
Ceiling Type Description
Rigid ceiling tiles If the tiles are particle board, plywood, gypsum board, or plaster, follow the instructions for
either tile ceilings or structural ceilings. They do not require support rails. However, support
rails may be needed if moisture or other environmental conditions could weaken the ceiling.
However, if the support rails are not used, the tiles must be strong enough to support the
loudspeaker by themselves. See “Support rails” below for more information.
Soft ceiling tiles If the tiles are a “soft” material (like mineral wool or glass fiber), follow the instructions for
ceiling tiles. Use the support rails with this type of ceiling tile. These tiles can bow or absorb
moisture and may not continue to support the loudspeaker’s weight.
Structural ceilings Follow the instructions for structural ceilings. Remove the support rails from the ceiling pans
before using the “structural ceiling” installation method.
Support rails
Not all ceilings require support rails. Only the installer can determine if a ceiling is strong enough to support the
loudspeakers by itself. If in doubt, consult a building trade professional, architect, or licensed professional engineer.
The support rails are 23
3/4 inches (60 cm) long, and will support a loudspeaker on a 2 foot  x  4 foot (0.6 m x 1.2 m) or
smaller tile. If the ceiling tiles are another size, the support rails will usually provide adequate support if they meet the
edge of the tile on at least two sides.
Follow these guidelines:
• For 60 cm tiles, place the ceiling pans and support rails at a 10° – 15° angle
10°  – 15°
•For 62 cm tiles, extend the rails in opposite directions until each rail reaches the ceiling grid on one side of the tile

WARNING
The springs are ready to use. Unhooking them, except as described in this guide, may cause personal injury. Always
wear safety glasses when installing loudspeakers.
CAUTION
If in doubt about the proper wire or connecting to the source or system electronics, have an audio profesional
complete the electrical connections.
CAUTION
Unplug all system components from electrical outlets before making connections.
2.1.1 Loudspeaker installation in a ceiling tile
•Do not unhook the springs.
•Cut a 5
3/4 inch (145 mm) hole for the loudspeaker. Use the loudspeaker box as a template to cut the correct hole
size.
Bose
® offers an optional hole saw (part number 179085) for use with a power drill.

2.2 Flush-mount loudspeaker enclosures
Note: If the electrical connections have not yet been made, pull all wires through the mounting hole and clear of the
springs.
Complete electrical connections before releasing the loudspeaker into the ceiling. Releasing the loudspeaker with
wires unconnected could cause the loudspeaker to jam on the dangling wires or damage the mounting hole or the
loudspeaker rim.
If the springs are to support the loudspeaker while making the electrical connections, complete Steps 1 and 2 only in
Section 2.1.2. Once the loudspeaker is hooked on the springs, continue with Section 2.3.4, “Rotation feature” and
Section 2.3, “Electrical connections,” then return to Step 3 of this section.
Note: Do not remove the protective shield from the loudspeaker until it is time to install the loudspeaker grille. The
loudspeaker grille may be installed when it is felt that subsequent installation steps or construction activities are not
likely to result in grille damage.

2.3 Electrical connections
2.3.1 Wire protection
Note: If local code requires flexible metallic tubing or flexible metallic conduit, be sure it is well supported. Too much
unsupported flexible metallic tubing or flexible metallic conduit can weigh the loudspeaker down, pushing it away
from the ceiling surface.
2.3.2 Wire preparation
Strip the wires to 5/16 inch (8 mm).
Note: Stranded wire is recommended. DO NOT solder (tin) the wires.
2.3.3 Wire connections
Note: Keep the following rule in mind when making the wire connections.
Red on the loudspeaker is connected to the + on the amplifier.
Black on the loudspeaker is connected to the - on the amplifier.

WARNING
An accidentally released spring can cause personal injury. Wear safety glasses. Keep hands and fingers clear of the
ceiling pan while moving the spring.
1.Return the springs to their locked position. If possible, pull the loudspeaker down and rehook the springs in their
locked position.
2.Lift the loudspeaker off the springs and remove it.
Note: If the springs cannot be rehooked, release them completely. Hold a spring by its hook and carefully release as
much tension as possible. Then release the spring. Repeat for the second spring.
