The SM42T-B from Atlas Sound is a surface-mount loudspeaker designed for professional, commercial, or residential applications where hi-fi sound is needed. The compact cabinet houses an efficient 4" polypropylene woofer and a 1" dome tweeter to provide a full frequency response. The TRX wave guide system provides wide dispersion of audio.
The weather-resistant construction allows you to use the speaker indoors or outdoors all year long. Internal Polyguard protection circuitry ensures that your speaker keeps running smoothly. An internal 16W, 70.7/100V transformer provides a strong performance, and may be bypassed for 8 Ohm operation. The speaker includes a heavy-duty C-bracket for mounting, and 1/4"-20 inserts let you integrate off-the-shelf security hardware.
