The white SM500i-II 5.25" Surface Mount Speaker from SoundTube Entertainment is a 5.25", two-way speaker with a midsize enclosure design that delivers low-end response (60 Hz) and optimal off-axis performance (2 to 10 kHz). The proprietary BroadBeam technology incorporates a high-frequency waveguide mated to a 1" convex aluminum tweeter with FerroFluid cooling. This helps deliver consistent high-performance audio across the operating bandwidth. The result is an audio system requiring fewer speakers with high intelligibility, offering reduced power needs, shorter installation time, and cost-effectiveness.
The SM500i-II Speaker features a low-profile grille and 6-position tap switch with transformer bypass. In addition the security knob reduces the chances of tampering after installation. Designed for indoor and damp outdoor locations to mid-level SPL surface-mount applications, the SM500i-II speaker comes with the Stealth bracket mounting system, allowing for an increased aiming angle. It also includes a detachable mounting plate designed for pre-mounting in either wall or pole applications. The speaker is suitable for music and paging in retail, amusement, restaurant, airports, hotels, schools and casinos.
BroadBeam waveguide technology delivers a consistent dispersion pattern up to 10 kHz for maximum coverage area per speaker
