The POLAR Wheel Board is the ideal accessory for easily transporting the POLAR 10 and POLAR 12 column systems. Handy features such as tailor-made cut-outs for the columns as well as milled holes for using tension belts to secure them, make everyday transportation of the POLAR 10 or POLAR 12 a breeze. What’s more, the slightly protruding edge of the wheel board protects the subwoofer from damage during handling.
