SoundTube's WX Weather Guard technology utilizes a dual layer hydrophobic material inside the speaker grille and an aluminum grille with powder-coat finish to keep water from the drivers and internal electronics in even the most extreme weather conditions. The speaker includes a higher power output for long throw and high SPL requirements as well as one 5.25-inch polypropylene woofer and one 1.0 inch, tractrix horn-loaded, convex aluminum dome tweeter in a ported enclosure. SM590I-II-WX has a 87.0 dB average sensitivity which offers high output capabilities and reduced amplification costs. The speaker has an easy access, six-position selectable tap switch for 25-, 70.7- and 100-volt applications with transformer bypass position and utilizes patented ZeroReflection enclosure technology for optimal sound reproduction and cabinet rigidity. Utilizing the new SM590I-II Stealth bracket mounting systems as well as vertical and horizontal pivoting allow the SM590I-II-WX to be aimed anywhere within the installation space and the low profile enclosure design keeps the speaker close to the wall. Safety cable with speaker mounting bolt, Euroblock connector, wall mount bracket and terminal weather boot are included. IP-Rating- IP44.
