The ultra-compact RealSound CS-81 features a single 1-inch compression tweeter loaded in a horn, paired with an 8-inch reflex bass driver.
The CS-81's exceptionally wide coverage makes it ideal for clubs, lounges, religious venues, museums, cafes, conference halls, and more—perfect for a broad range of live sound reinforcement applications.
Featuring a uniquely designed wall-mounted structure with ABS housing and foam insulation, this speaker is waterproof for easy cleaning, equipped with a sound-permeable steel mesh. It comes complete with 4 M6 mounting screws for attaching the CS-specific suspension bracket, enabling a versatile hanging system that can be installed either horizontally or vertically—and includes an additional M6 screw as a safety anchor point.
The CS-81 features a compact, petite, and elegantly rounded design. Its dual-purpose functionality allows it to seamlessly handle both main PA reinforcement and stage monitoring applications.
