The SM400i is a 4" coaxial, ported speaker with a low-profile surface mount enclosure design for indoor/outdoor applications that delivers a consistent dispersion pattern (2 to 10 kHz, independently verified.) Mounting hardware is included and features a corrosion- and theft-resistant Stealth™ U-bracket for easy and secure installation. Nearly invisible from sightlines, the Stealth™ U-bracket includes one-way fasteners for tool-free, theft-resistant security. SoundTube®'s custom-engineered driver and electro-acoustic network deliver high-performance sound in a cost-effective surface-mount speaker design. The SM400i speaker incorporates a five-position tap switch with a transformer bypass position for simplified ordering and stocking. Corrosion and theft-resistant U-bracket mount with safety cable, Euroblock connector, paint mask, terminal weather boot, and port plugs are included. Included port plugs can be used for added weather resistance.
