• Operation with 70V, 100V or low impedance
amplifier output
• Transformer tap adjustment with settings
under the grille
INSTALLATION
Product installation instructions are included
with the loudspeakers.
A full complement of accessories, for ease
and versatility of installation, is available
from Bose.
For mounting in a tile ceiling, a tile bridge
is required for the Acoustimass module and
is available for the FS3F satellite speaker.
Rough-in pans are available for flush-mounting
in hard ceilings or walls (and required for
installing the module that way). The Bose
8/32 junction box may be used with the
rough-in pan or tile bridge for pre-wiring
that meets local building codes.
For pendant-mounting in an open ceiling,
the FS3B pendant-mount kit offers a suspen-
sion cable, eye bolts for cable installation,
and a cosmetic cover for the module. For the
FS3F satellite speakers, an optional cosmetic
cover can be used in conjunction with solid
conduit attached to the satellite rear cover.
An optional surface-mount kit for the module
provides a wall- or ceiling-mount bracket
and cosmetic cover that coverts the series II
module into a surface-mount speaker.
The surface-mount satellite speakers include
mounting brackets that allow for easy installa-
tion and aiming at ±30° pitch and ±90° yaw.
The FS3F and FS3B plenum covers allow
each loudspeaker to meet fire codes for
installing in air-handling spaces.
Note: This product is equipped with a
protection circuit that reduces the volume
to a very low level when over-powered.
In the event that the protection circuit is
activated, turn off the signal source for
30 seconds for full recovery.
LOUDSPEAKER CONFIGURATION
The FreeSpace 3 loudspeaker system consists
of a flush-mount Acoustimass module plus
two to four satellite speakers of flush- or
surface-mount design. The module may also be
mounted on the surface of a wall or ceiling
using the optional surface-mount kit.
The module alone may be used for bass
augmentation with other Bose speakers, such
as the FreeSpace model 16, model 32, model
32SE or FreeSpace 6 loudspeakers.
With loudspeakers other than the FreeSpace 3
satellites, the module must have a separate
amplifier channel and must not connect to
the other speakers.
Detailed installation and setup instructions
are provided in the Bose FreeSpace 3-II loud-
speaker system installation guide found on the
website http://pro.bose.com.

The module shall have an input impedance
of 6Ω for direct connection to unequalised
low-impedance amplifier sources.
The system shall be configured for use with
either a 70/100V input or a low-impedance
input. The transformer shall offer multiple
taps of 25W, 50W, 100W, and 200W.
Each satellite speaker shall have one 2.5"
(6.3 cm) full-range driver. The nominal
average dispersion shall be 170° at –6dB.
The input connectors shall consist of multi-
position screw-type barriers on the
Acoustimass module, a two-position guillotine
connector on the flush-mount satellite, and
a two-position screw-type barrier on the
surface-mount satellite. Wire jumpers for
transformer settings shall be provided.
Removable covers shall shield all bass
module input and jumper connections.
The Acoustimass module shall have dimensions
of 15.4" (39.1 cm) outer flange diameter;

10.2 cm) and shall weigh 1.75 lb (0.8 kg).
Each flush-mount satellite speaker shall
measure 6.2" (15.7 cm) outer flange
diameter; 5.0" (12.7 cm) ceiling hole
diameter; and 5.0" (12.7 cm) to top of
housing. It shall weigh 1.9 lb (0.9 kg).
The loudspeaker module and flush-mount
satellite enclosures shall be composed of
PC/ABS with an expanded metal grille and
shall meet plenum ratings when used with
a plenum cover. The surface-mount satellite
shall have a cloth grille and black or white
polymer finish.
The loudspeaker shall be the Bose FreeSpace
3-II loudspeaker system.
