FreeSpace® 3
subwoofer/satellite systems
Key Features
• Subwoofer/satellite systems that deliver high fidelity and extended-
bandwidth reproduction of voice and music for a wide range of installed
applications, including retail, restaurant and hospitality operations
• Modular design supports the flexibility for use of 2 or 4 satellites per
Acoustimass bass module, and parallel connection of bass modules
• Mix and match surface-mount and flush-mount components to work
with different room decors and layouts for a variety of applications
• Flush-mount components are plenum rated when used with the
optional plenum cover
• Selectable 70/100V or low impedance with transformer tap adjustment
on Acoustimass bass module
• Can be configured for stereo or mono operation
Product Overview
The Bose® FreeSpace® 3 subwoofer/satellite systems are high-performance, extended-range loudspeaker systems designed for small
to medium-sized installed applications requiring high fidelity and extended bandwidth reproduction of voice and music. Surface and flush
components can be mixed and matched to provide greater flexibility to suit a wide range of applications. FreeSpace® 3 systems feature
a wide coverage pattern and frequency response down to 40 Hz.

Architects’ and Engineers’
Specifications
The loudspeaker system shall be a 200 watt ported loudspeaker
system that includes one Acoustimass® module and two or four
satellite speakers. It shall be capable of producing 93 dB SPL
average in a 45,000 ft3 room with an RT60 of 1 second in a range
of 50 Hz to 16 kHz (±3 dB).
The module shall have one 5.25" (133 mm) dual voice coil low
frequency driver. The module shall have an input impedance of
6 ohms (5 ohms for surface-mount module) for direct connection
to un-equalized low impedance amplifier sources. The system
shall be configured for use with either a 70/100 V input or a low
impedance input. The transformer shall offer multiple taps of 25
W, 50 W, 100 W, and 200 W.
Each satellite speaker shall have one 2.5" (64 mm) full-range
driver. The nominal average dispersion shall be 170° at –6 dB.
The input connectors shall consist of multi-position screw-type
barriers on the flush-mount Acoustimass module, a spring-type
barrier connector for the 70/100 V inputs and a screw-type barrier
strip for direct 4-8 ohm input on the surface-mount Acoustimass
module, a two position guillotine connector on the flush-mount
satellite, and a two position screw-type barrier on the surfacemount satellite. Wire jumpers for transformer settings shall be
provided. Removable covers shall shield all bass module input
and jumper connections.
The flush-mount Acoustimass module shall have dimensions of
15.4" (391 mm) outer flange diameter; 14.25" (361 mm) ceiling
hole diameter; and 7.5" (190 mm) height to top of housing. It shall
weigh 14 lb (6.36 kg). The surface-mount Acoustimass module
shall have dimensions of 14.0" H x 8.7" W (w/bracket) x 13.6"
D (356 mm x 221 mm x 345 mm) and shall weigh 17.5 lb (7.9
kg) with attached mounting bracket. Each flush-mount satellite
speaker shall measure 6.2" (157 mm) outer flange diameter;
5.0" (127 mm) ceiling hole diameter; and 5.0" (127 mm) to top
of housing. It shall weigh 1.9 lb (0.9 kg). Each surface-mount
satellite speaker shall measure 3.0" H x 3.0" W x 4.0" D (77 mm x
77 mm x 102 mm) and shall weigh 1.75 lb (0.8 kg).
The flush-mount Acoustimass 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 Acoustimass enclosure shall be
composed of high-density wood composite with solid color PVC
laminate, black or white. The surface-mount satellite shall have a
cloth grille and black or white polymer finish.
The loudspeaker shall be the Bose® FreeSpace® 3 loudspeaker
system.
