Please read this guide
Bose® FreeSpace® Model 8 and Model 32 loudspeakers are significantly different
from conventional ceiling loudspeakers, both in operation and installation. We
recommend this guide be read carefully.
Safety Information
1.1 Read the instructions – Read and keep all safety and operating instructions.
1.2 Follow cautions – For safety, follow all cautions and warnings in this guide
and on the loudspeakers.
1.3 Avoid moisture – Do not install the loudspeakers near water or excessive
humidity. This includes installations near spas, swimming pools, dish washing and laundry equipment, and cooking areas. Avoid installing outdoors.
1.4 Avoid heat – Do not install the loudspeakers near excessive heat sources.
This includes installations near or above radiators, ranges, grills, fryers,
stoves, or other appliances.
1.5 Protect cables – Always route cables so heavy or sharp objects cannot
pinch or cut them.
1.6 If damage occurs – Service by a qualified service person if:
A. Water or other liquids leak into the loudspeakers;
B. The loudspeaker cone is dented or punctured before the grille is in-
stalled;
C. The loudspeakers do not operate normally even though the instructions
in this guide have been followed;
D. The loudspeakers exhibit a distinct change in performance.
1.0 Safety Information
WARNING
To reduce the risk of fire or electrical shock, do not expose these loudspeakers to
moisture.
WARNING
Bose Model 8 and Model 32 loudspeakers are electrical appliances. There are no
user-serviceable parts inside. As with all electrical appliances, dangerous
electrical shock may result if unqualified personnel attempt repair. Only qualified
personnel should perform service and installation.

2.0 Bose® FreeSpace® Model 8 And Model 32 Loudspeakers
Bose designed the FreeSpace Model 8 and Model 32 loudspeakers to provide
high fidelity voice and music reinforcement in commercial settings. These Virtually Invisible® loudspeakers meet the aesthetic demands of most architectural
designs. The loudspeaker rim and grille can be painted to match the setting.
Bose has an information sheet explaining how to paint the rim and grille.
Call 1-800-996-BOSE and ask for a copy of 183073 Loudspeaker Painting.
FreeSpace Model 8 loudspeakers are available in two versions: 100V (Europe and
Japan only) and 70V (North America only). FreeSpace Model 32 loudspeakers are
available in three versions: 100V (Europe and Japan only), 70V (North America
only) and 4Ω (worldwide). All 70V and 100V versions require a Bose approved
equalizer, such as the Bose FreeSpace (Model 8/32) system controller. Using the
loudspeakers without an approved equalizer causes inferior acoustic performance and may damage the loudspeakers. The 4Ω version of the Model 32
loudspeaker does not require an approved equalizer. It is compatible with the
FreeSpace BMA-125 business music amplifier and other amplifiers.

2.0 Bose® FreeSpace® Model 8 And Model 32 Loudspeakers
All versions meet all regulatory standards for ceiling loudspeakers and are UL
listed as vandal resistant. A 70V fire safety version of each model, available only
by special order, is also UL listed as a fire protective signaling device. Complete
safety agency listings and special requirements for fire protective signaling and
warning systems are contained in Appendix C, “Safety Requirements.”
For seismic security, the loudspeaker enclosures and mounting pans have holes
for attaching security wires. Used with appropriate hardware, these attachment
points may qualify the loudspeakers as earthquake resistant. Check local building
codes.
In North American loudspeaker installations, both UL and CSA permit the use of
Class 2 wire (CL2, CL2P, or CL2R) for loudspeaker wire. If the wire passes through
a plenum, only CL2P is acceptable. Since most commercial ceiling spaces are
used as plenums, most installations will require CL2P. In risers such as vertical air
handling ducts or any through passage from floor to floor, CL2R is classified for
this use. To maintain compliance with plenum installations, use metallic electrical
connectors.
See Table 725-53 of the National Electric Code (NEC) for a list of acceptable wire
substitutes.
It is recommended that the fire marshall or building inspector be consulted before
installing these loudspeakers in air handling spaces (plenums) because some
areas require the use of metallic conduit or metallic tubing.
2.1 Unpacking the loudspeakers
Unpack the loudspeakers carefully (Figure 1). Save the carton and all packing
materials.
If any part appears damaged, do not install the loudspeakers. Repack them and
immediately notify Bose Service or your authorized Bose Professional Products
dealer.
For the most efficient installation, review this section and plan ahead before wiring
and installing Bose FreeSpace Model 8 or Model 32 loudspeakers.

3.0 Before You Begin
3.1 Ceiling type
Evaluate the ceiling construction BEFORE beginning installation. Ceiling type,
thickness, and strength determine the installation and connection methods as
well as the necessity of support rails. A qualified person, such as a building trade
professional, architect, or licensed professional engineer, should make these
determinations.
Bracket installation
This guide covers installation methods for both ceiling tile and structural ceilings.
Structural ceilings – Follow the instructions for structural ceilings.
Soft ceiling tiles – If the tiles are made of a “soft” material (like mineral wool or
glass fiber), follow the instructions for ceiling tiles. This will provide extra support.
Rigid ceiling tiles – If the tiles are made of particle board, plywood, gypsum board
or plaster, follow the instructions for ceiling tiles. Or, follow the instructions for
structural ceilings. However, the tiles must be strong enough to support the
loudspeaker without the help of the support rails. See “Support rails” below for
more information.
Support rails
Not all ceilings require the use of the support rails. Only a qualified person, such
as a building trade professional, architect, or licensed professional engineer,
should determine if a ceiling alone is strong enough to support the loudspeakers.
Ceiling tiles – Use the support rails with any ceiling tile made of mineral wool,
fiberglass, or other fibrous material. These tiles do not remain flat, may absorb
moisture, and may not always support the loudspeaker’s weight.
The support rails are 23 3/4" (603 mm) long and will support a loudspeaker in a 2'
x 4' 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 600 mm tiles, place the mounting pans and support rails at a 10°–15° angle
(Figure 2).

For 625 mm tiles, extend the rails in opposite directions until each rail reaches the
ceiling grid on one side of the mounting pan.
Ceiling tiles made of particle board, plywood, gypsum board, or plaster usually do

not require support rails. However the support rails may be needed if moisture or
other environmental conditions may weaken the ceiling.
Structural ceilings – The support rails and spacers must be removed from the
ceiling pans before using the structural ceiling installation method.
Rotation feature
FreeSpace® Model 8 and Model 32 loudspeakers can be rotated on their springs
to conveniently access the terminals after installation. The ceiling pan and springs
hold the speaker in place while the tap settings are changed or electrical connections are completed (see Figures 21 and 22 on page 15). Be careful not to damage
the mounting hole when turning or releasing the loudspeaker.
Do not use the rotation feature if the loudspeakers are installed in a very thick
ceiling. In general, the rotation feature works with FreeSpace Model 8 loudspeakers installed in ceilings up to 2" thick, and with FreeSpace Model 32 loudspeakers
installed in ceilings up to 1" thick. To be certain, install one loudspeaker and
attempt rotation as described in Section 4.3, “Electrical connections.”
3.2 Clearance
Allow enough clearance for both the depth of the loudspeaker and the wire from
the electrical fitting. To decrease this distance, use an angled electrical fitting with
flexible metallic conduit or flexible metallic tubing.
