Description
The SM400i is a 4Ó, coaxial, ported speaker with a low-profile surface-mount enclosure design for indoor/outdoor applications that delivers a consistent dispersion pattern (2-10 kHz, independently verified). Mounting hardware is included and features a corrosion and theft-resistant Stealthª U-bracket for easy and secure installation. Nearly invisible from sight-lines, the Stealth U-bracket includes one way fasteners for tool-free theft-resistant security. SoundTubeÕs custom-engineered driver and electroacoustic network deliver high-performance sound in a cost-effective, surface-mount speaker design. The SM400i speaker incorporates a five-position tap switch with transformer bypass position for simplified ordering and stocking. Included port plugs can be used for added weather resistance.
Features:
- BroadBeam¨ waveguide technology delivers a consistent dispersion pattern up to 10 kHz for maximum coverage area per speaker (independently verified).
- One 4Ó (102 mm) polypropylene woofer and one 1Ó (25.4 mm) convex titanium tweeter with FerroFluid cooling.
- Includes port plugs and weatherized components for indoor and outdoor applications.
- Patented ZeroReflectionª enclosure technology for optimal sound reproduction and cabinet rigidity.
- Easy access, five-position selectable tap switch for 25, 70.7, and 100 V applications with transformer bypass position.
- Iridite-plated aluminum grille with protective powder-coated finish for lasting durability.
- Includes a tool-free Stealthª U-bracket mounting system for fast and secure installation.
