The Becke IP-Rated Waterproof Sound Column is a high-performance industrial-grade 30W audio device, engineered for extreme indoor and outdoor environments with IP65 dust-tight and water-spray resistant protection. As a flagship professional public address (PA) solution, it combines rugged corrosion-proof hardware with high-fidelity audio technology, delivering clear, consistent sound for public broadcasting, emergency notifications, and background music. Ideal for industrial manufacturing, education, transportation and public infrastructure, it bridges standard audio speakers and specialized outdoor PA systems, performing reliably where conventional speakers fail.
Prioritizing clear, loud sound reproduction even in noisy environments, the sound column delivers a 30W primary power output with a 100V line PA system (compatible with most commercial/industrial amplifiers) and scalable variants for larger coverage. It features a wide frequency response of 100Hz–18kHz, a high sensitivity rating of 92dB–95dB SPL (1W/1m), and a maximum sound pressure level of 110dB–115dB, cutting through moderate to high background noise. With total harmonic distortion (THD) below 1% at rated power, it ensures accurate audio reproduction, while the linear speaker array optimizes sound dispersion (120°–150° horizontal, 30°–45° vertical), directing sound to target areas and maximizing coverage efficiency. Its high impedance (1kΩ–2kΩ at 100V) allows multiple units to be connected in parallel to a single amplifier for large-scale installations.
Designed for easy installation and seamless integration with existing analog/digital PA systems, the sound column comes with all necessary hardware, supporting tool-free angle adjustment for both mounting methods to fine-tune sound direction. It uses standard 100V line wiring, with clearly labeled waterproof audio input terminals (accepting 2/4-core cables) in a sealed compartment, reducing wiring errors. Compatible with PA amplifiers, mixers and IP network PA controllers, it suits both new installations and retrofits. Its fully sealed design has no moving parts, minimizing maintenance requirements, while the modular structure allows easy access to internal components via a removable steel mesh grille and sealed wiring cover, cutting repair time and downtime in critical environments.
