The Adastra CH15 has been engineered for both professional installers and industrial audio applications. Designed to deliver clear, reliable sound in general-purpose PA and industrial settings, it's well-suited to environments such as factories, workshops, warehouses, outdoor public spaces, and evacuation systems.
The CH15 features a lightweight yet rugged aluminium horn that optimises sound projection while maintaining structural strength. Its steel bracket is easily adjustable, enabling precise angling. The compact disc-style body is robust, and the IP33 design shields against moderate dust and water sprays.
