Overview
Deliver consistent, intelligible sound where it matters most — the SoundTube SM400I-WH 4" coaxial ported surface mount speaker is engineered for professional installed audio and security-grade paging. Its BroadBeam waveguide gives verified 2–10 kHz dispersion for clear voice reproduction, making it ideal for surveillance monitoring, emergency announcements and retail paging. Weatherized components, an Iridite-plated powder-coated grille and IP4X-rated enclosure provide corrosion and moisture resistance for both indoor and outdoor use.
The SM400I combines a 4" polypropylene woofer and 1" aluminum tweeter with FerroFluid cooling for reliable performance at up to 20W RMS, while the five-position tap switch (including transformer bypass) accommodates 25/70.7/100V systems or low-impedance installs, reducing design complexity. Installers benefit from the nearly invisible, theft-resistant Stealth™ U-bracket, included safety cable and quick-connect Euroblock for fast, secure deployments.
