SC-10, SC-15 and SC-30 are high quality square type Horn Speakers providing performance even in the harshest environments. Straight and ultra-high power horns give a highly articulate sound performance in high noise areas or at large gatherings of people. All models include a line transformer for 100V constant voltage operation. A tap switch is available at the back of the speaker to change the impedance for different power applications. The bracket is “U” shaped and makes easy the mounting on any support for multi-directional coverages. Made of ABS resin, the devices are IP66 and can be used any places indoor or outdoor.
