AtlasIED SM52T-B 5.25" 2-Way 70V All Weather Surface Mount Speaker

The AtlasIED SM52T-B is engineered for system integrators and installed sound professionals who need a reliable, all-weather 70V distributed speaker for permanent installations. The compact two-way enclosure pairs a polypropylene woofer with a FerroFluid-cooled titanium dome tweeter controlled by the TRX WaveGuide for consistent 90° horizontal by 90° vertical dispersion—whether the cabinet is mounted vertically or horizontally. The symmetrical high-frequency design eliminates the need to reposition the speaker based on orientation, a practical advantage when coordinating multi-zone installs across varied mounting surfaces.

The internally mounted 30-watt transformer supports 70.7V and 100V line operation with an 8Ω bypass, and six tap settings are screwdriver-selectable via a sealed rear switch—no tools or panel access required after installation. A tongue-in-groove cover with a rubber wire exit grommet protects the input barrier strip and transformer assembly from moisture ingress, critical for covered outdoor venues, natatoriums, or transit environments where humidity is a constant concern. The UV-resistant, talc-impregnated polypropylene cabinet, powder-coated aluminum grille, and all-brass hardware inserts are validated against 100-hour salt spray testing per ASTM B117, making the SM52T-B appropriate for coastal and high-humidity deployments that would degrade standard ABS enclosures.

The included zinc chromate plated C-bracket accommodates vertical or horizontal surface mounting and accepts a 5/8"-27 thread for AtlasIED mic stands in near-field applications. Rear OMNIMOUNT inserts and standard 1/4"-20 hardware inserts allow integration of third-party or vandal-resistant fasteners without modification, suiting installations in schools, transit hubs, and public-access facilities where security and long-term serviceability matter.
