Danley OS15CX-G Outdoor Coaxial Loudspeaker With Bracket | GreyThe Danley OS15CX is built for outdoor sound reinforcement where durability and consistent coverage matter. It uses a 15" 1. 3" coaxial driver in a compact full range Synergy Horn design intended for shorter throw applications. By combining frequency bands through Danleys Synergy crossover approach, the speaker is designed to behave more like a single source, helping maintain intelligibility and tonal consistency beyond the immediate listening area.
