HK Audio WB-4 Wheel Board – Professional Wheel Board for L Sub 4000 / L Sub 4000 A

The HK Audio WB-4 WHEEL BOARD is a professional wheeled board specifically designed for the safe and rapid transport of the HK Audio L SUB 4000 and L SUB 4000 A subwoofers. It features four 100mm wheels that provide smooth rolling even with heavy loads and on common touring surfaces. Two of these wheels have brake mechanisms to lock the assembly during loading, unloading or when the system is parked. The platform includes two integrated handles that facilitate maneuvering, stacking and placement in a van or warehouse, and also protects the cabinet's finish by reducing direct friction with the floor.
