Atlas Sound SM42T-WH – 4" 2-Way Weather Resistant Speaker Pair (White)

Product Overview

The Atlas Sound SM42T-WH is a 4-inch 2-way weather-resistant surface-mount loudspeaker system sold as a matched pair in white, making it well-suited for indoor/outdoor commercial audio installations including restaurants, retail stores, boutiques, corporate environments, and houses of worship. Each speaker includes a screwdriver-adjustable 16-watt 70.7V/100V transformer for integration with distributed constant-voltage audio systems, while also supporting direct 8-ohm operation for locally amplified setups. The 2-way design pairs a 4-inch polypropylene woofer with a 1-inch Ferrofluid-cooled dome tweeter, delivering full-range frequency response from 115 Hz to 16 kHz for both music and voice reproduction. A color-matched heavy-duty C-shaped mounting bracket is included with each speaker.

Product Description

The SM42T-WH surface-mount speaker features weather-resistant construction that enables year-round deployment in outdoor patios, covered walkways, building exteriors, and similar environments exposed to humidity and temperature variation. The TRX WAVEGUIDE constant-directivity high-frequency waveguide system maintains consistent horizontal and vertical dispersion across the tweeter’s operating range, improving off-axis intelligibility at listening positions away from the speaker’s primary axis. The Atlas Sound POLYGUARD high-frequency protection circuit safeguards the tweeter from transients and overload conditions, extending component life in demanding commercial applications. The 16-watt 70.7V/100V transformer is screwdriver-adjustable and can be bypassed entirely for direct 8-ohm operation, providing flexibility for both distributed and local amplifier configurations. All 1/4"-20 hardware inserts on the enclosure accept standard security hardware, allowing these speakers to be integrated into secure mounting systems common in hospitality and retail environments. The heavy-duty zinc chromate plated and powder-coated C-shaped mounting bracket is color-matched in white and supports multi-position installation for optimum coverage angle adjustment. OMNIMOUNT compatibility is also supported for installations where alternative mounting hardware is preferred. Each SM42T-WH unit measures 7.0" H x 5.0" W x 5.9" D and carries a 5-year limited warranty. Sold as a pair.
