The SM Series loudspeaker systems are EN54-24 certified and built to withstand tough environments, delivering exceptional sound in a sleek, compact design. Featuring a highly efficient woofer and a ferrofluid-cooled Mylar high-frequency driver, these speakers ensure clear, balanced audio. The TRX Control WaveGuide optimizes sound clarity, providing smooth, even 90-degree x 90-degree coverage, whether mounted vertically or horizontally. High-frequency protection is guaranteed with AtlasIED’s Poly Guard circuit.

Designed for versatility, the SM42TEN-B and SM42TEN-WH models include a 16-watt 70.7V/100V transformer with adjustable taps for distributed audio. Their weather-resistant construction features UV-resistant polycarbonate ABS cabinets, polypropylene woofer cones, powder-coated aluminum grilles, and brass hardware, ensuring durability in harsh environments.

Installation is made simple with a C-bracket that supports vertical or horizontal mounting on most surfaces, as long as they are strong enough to hold the speaker. Additional mounting options include a 15mm threaded hole for microphone stands or brass inserts for compatibility with AtlasIED and OMNIMOUNT™ brackets. A sealed 2-pole terminal strip accommodates up to two #16AWG wires, and wattage taps (2, 4, 8, and 16 watts) can be easily adjusted via a sealed switch. The internal transformer can also be bypassed for 8ohm operation.
