BOSE / FS3-4B

Delivers rich, powerful sound without compromising the interior design.

~From the manufacturer's website~
■Speakers required for commercial spaces such as boutiques, cafeterias, and showrooms not only require high-quality sound, but also performance that covers every corner of the store and a design that blends seamlessly into the interior.

The FS3-4 features apple-sized satellite speakers and a base module that employs Bose's proprietary Acoustimass technology, delivering rich, powerful sound reproduction over a wide coverage area without compromising the interior design.

■Uses 5.7cm wide-range satellite speakers for mid- and high-frequency ranges
The 5.7cm wide-range satellite speakers provide excellent sound diffusion and uniform acoustic balance across a wide area. Furthermore, combining them with dedicated mounting brackets allows for flexible acoustic design.

■Uses Bose's proprietary Acoustimass technology for bass reproduction
The base module employs Bose's proprietary Acoustimass technology for bass reproduction, applying the principles of resonance and resonance to deliver clear, distortion-free bass reproduction. Since it has no directional characteristics, it can be installed in dead spaces such as the ceiling or in the corner of a room.

■Enables flexible acoustic design
A wall-mounting bracket is included for easy installation and swing angle adjustment, and a sleek, protective panel cover is included for the bass module's terminals. The bass module can also be installed inside the ceiling using separately sold brackets. The unit is available in standard white and black colors. Latex- and oil-based paint finishes are also available.

■Compatible with both high-impedance and low-impedance transmission methods
A transformer with adjustable tap is built into the bass module, supporting 70V and 100V lines. (Bypass is also possible.)
