Overview
Designed for clear, dependable audio in commercial and security-focused environments, the SoundTube RS400I-BK 4" Hanging Speaker brings intelligible paging and background music to retail, hospitality, and surveillance applications. This pro speaker combines a 4" polypropylene woofer with a 1.0" convex titanium tweeter (FerroFluid cooled) and patented BroadBeam waveguide to deliver consistent coverage and measured 125° off-axis performance between 2–10 kHz. With a frequency range down to 76 Hz and up to 22 kHz, the RS400I-BK reproduces voice and music with authority and clarity.
Installation is quick and secure using the included UL-listed hanging hardware, SpeedClamp self-locking wire grip, Euro-block connector and terminal weather boot — reducing labor on large deployments. The six-position transformer tap supports 25, 70.7 and 100 V systems (plus bypass), making the RS400I-BK an ideal choice for multi-zone PA, security monitoring, and surveillance integration. Weatherized components and a powder-coated steel grille ensure rugged longevity in demanding sites.
Specify the SoundTube RS400I-BK for projects that require reliable, wide-coverage audio for security, monitoring and public address — contact sales or add to cart to start your deployment.
