A Rugged Speaker Built for Clear Outdoor/PA Performance

The Sonora 4TB is a surface-mount loudspeaker with both 100-V line transformer and low-impedance options, designed for background music, public address, or emergency announcements. With a 4″ polypropylene woofer and a 1″ tweeter, it delivers crisp, distortion-free sound from 120 Hz up to 20,000 Hz, great for both voice and music. It’s built tough for outdoor environments with salt mist and waterproof protection.

Versatile Mounting & Compliance for Safety & Installations

This speaker includes an adjustable weather-proof mount, stainless steel screws, and a safety steel cable for secure installation. Rated IP-66 for protection against dust, rain, and harsh marine environments, it’s optimized for commercial installations—including voice-alarm systems thanks to compliance with EN 54-24 in the “EN” version. Multiple power taps (30 W, 15 W, 7.5 W, 3.75 W) allow matching to different zones.
