The CX-DSP4120 is a professional 15W outdoor column speaker designed for clear background music and public address applications. It is suitable for hotels, shopping malls, supermarkets, schools, entertainment venues, corridors, public areas, and commercial PA installations. With its slim column design and outdoor-friendly structure, it provides a clean and practical sound solution for fixed wall-mounted audio projects.

The speaker adopts a two-way frequency division structure with a dome tweeter and 4-inch full-range unit, delivering clear sound and wider frequency response. Its bell-shaped cavity structure helps increase column strength and reduce cabinet resonance for better sound quality. The waterproof design, aluminium surface mesh, and weather-resistant ASA engineering plastic enclosure make it suitable for long-term outdoor use without discoloration or aging.
