Applications

The SoundTube RS55i is a compact, premium 2-way loudspeaker solution for general background or satellite/subwoofer applications. The RS55i is specifically designed for applications requiring full- range background music plus clear, intelligible paging. The wide coverage pattern makes the RS55i an ideal choice for use in museums, retail establishments, restaurants, outdoor applications and open-ceiling environments.

For applications where additional bass is required, an RS801i SoundTube subwoofer may be added.

Cast Composite Enclosure

SoundTube’s RSi Series cast composite enclosure provides a low-resonance plat- form with effective self-damping properties for a clean, tight sound. Compression cast glass-fiber composite material coupled with SoundTube’s patented ZeroReflec- tion™ internal shaping provide extreme stiffness, eliminating internal standing waves and external diffraction distortions. The result is accurate sound and tight bass in a commercial speaker.
