The POLAR Wheel Board from HK Audio is the ideal accessory for easy transport of the POLAR 10 and POLAR 12 column systems. Practical features such as precisely fitting cut-outs for the columns as well as milled holes for the use of tensioning straps for securing, facilitate the transport of the POLAR 10 or POLAR 12 in everyday life. The slightly protruding edge of the wheel board additionally protects the subwoofer from damage during handling.
