Atlas Sound SM42T Overview
Sold as a pair, the black Atlas Sound SM42T-B is a weather-resistant, surface-mount loudspeaker offering consistent coverage and installation flexibility for indoor/outdoor environments such as retail shops, restaurants, warehouses, and more. The compact cabinet houses an efficient 4" polypropylene woofer and a 1" dome tweeter to deliver a frequency response of 115 Hz to 16 kHz. The TRX high-frequency waveguide system provides even 90 by 90° dispersion.
The integrated 16W transformer offers selectable power taps and allows the SM42T-B to be driven by 70V, 100V, or 8-Ohm power amplifiers (available separately). Internal PolyGuard circuitry protects the tweeter without compromising high-frequency performance. A removable cover guards the 2-pole barrier strip input, which accommodates wires up to 14 AWG. The SM42T-B includes a heavy-duty, C-shaped bracket for versatile horizontal or vertical mounting.
