AtlasIED SM42T-B 4" 2-Way All-Weather Speaker with 16W 70V, 100V Transformer, Black

Designed for reliable outdoor and indoor audio in commercial and security applications, the AtlasIED SM42T-B 4" 2-way all-weather speaker delivers clear, intelligible sound for paging, monitoring and background music. This AtlasIED pro speaker pairs a highly efficient 4" polypropylene woofer with a 1" ferrofluid-cooled dome tweeter to reproduce voice and music with crisp highs and solid midrange — ideal for boutiques, restaurants, corporate AV and surveillance perimeter paging. The screwdriver-adjustable 16W 70.7V/100V transformer (with 8 Ω bypass) makes integration into existing distributed audio or security paging systems fast and flexible. Weather-resistant aluminum and zinc-plated hardware plus an included powder-coated C-bracket ensure durable outdoor performance and easy mounting with Omnimount and common surveillance hardware. With 88 dB sensitivity and a rugged design backed by a five-year warranty, the SM42T-B reduces downtime and maintenance for large deployments.
