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.
