The enclosure is constructed from high-quality Baltic birch plywood, ensuring acoustic integrity, durability, and long operational life even under demanding conditions.

The system is equipped with IP67-rated Amphenol connectors, providing secure and weather-resistant connectivity for outdoor use. A rugged steel grille with water-repellent and acoustically transparent protection shields the transducer from dust, moisture, and debris while preserving sound clarity. Its integrated rigging and hardware design allow fast deployment and flexible positioning in professional setups.
