The MDF enclosure is finished with black acrylic enamel, providing both durability and a sleek, professional appearance. Equipped with M8 rigging points, the PR:O 18 S is also suitable for installation in acoustically challenging environments, allowing for easy integration into custom setups. The metal grille with black acoustic foam adds protection to the subwoofer, ensuring it performs at its best over time.

For versatility and ease of use, the PR:O 18 S features two Speakon NL4 connectors for reliable and secure connections, and a pole mount with an M20 thread for easy attachment to speaker poles. Integrated carrying handles make transportation simple, while optional 100 mm casters provide added mobility for easy setup and movement.
