Atlas Sound SM42T-B 2-Way 16W Weather-Resistant Surface Speaker (Pair)

Weather-Resistant Surface Mount Speaker for Indoor and Outdoor Audio Systems

This compact 4-inch surface-mount loudspeaker is designed to deliver clear, consistent sound in both indoor and outdoor environments. Built for commercial and professional audio systems, it provides reliable performance for background music and paging in retail spaces, restaurants, warehouses, offices, and covered outdoor areas where durability and sound clarity are required.

Two-Way Speaker Design for Balanced Sound Coverage

The speaker features a two-way design with a 4-inch polypropylene woofer and a 1-inch tweeter, producing clear midrange response and detailed high frequencies. This configuration supports intelligible speech and smooth music playback, making it suitable for distributed audio systems where consistent tonal balance matters across multiple listening areas.

Wide Dispersion with Integrated High-Frequency Waveguide

A built-in high-frequency waveguide delivers even sound dispersion across a wide coverage pattern. This helps reduce hot spots and dead zones, ensuring listeners experience consistent audio levels throughout the space. The controlled dispersion makes the speaker effective in both open areas and acoustically challenging environments.

Selectable Power for 70V, 100V, or Low-Impedance Systems

An internal 16-watt transformer allows the speaker to operate on 70V or 100V distributed audio systems, as well as standard 8-ohm amplifier outputs. Screwdriver-selectable power taps make it easy to match output levels to system requirements, simplifying installation and system balancing.

Weather-Resistant Construction for Long-Term Reliability

The enclosure is designed to withstand exposure to moisture and varying environmental conditions, allowing use in indoor or outdoor installations. This weather-resistant construction makes the speaker a dependable choice for covered patios, entryways, and other semi-exposed locations.

Flexible Mounting for Versatile Installation Options

A heavy-duty C-shaped mounting bracket is included, allowing horizontal or vertical positioning. Standard threaded inserts and mounting compatibility support a wide range of installation hardware, giving installers flexibility when integrating the speaker into walls, ceilings, or structural surfaces.
