The cabinet is made of high-quality birch plywood with weather-proof outer treatment. The subs are lightweight and stackable, with eight M10 threaded inserts to allow easy rigging. Two M20 threaded pole mounts on the top and side allow the woofer to be used in vertical or horizontal configurations, with rubber feet on both sides. Two stabilizing brackets make the vertical placement stable and firm. The heavy-duty coating, the powder-coated metal grille, and the rugged structure of the cabinet withstand long-term use and transportation. Separate housing for the amplifier guarantees component efficiency and reliability. An acoustically transparent sound foam backing on the inside of the grille ensures protection from dust and humidity.
