This direct radiating 2 x 10' subwoofer delivers exceedingly faithful impulse response enabling powerful, natural-sounding, low-end performance. The compact dimensions and integrated rigging hardware afford maximum flexibility for both flown and ground-stacked configurations. The CDR 210 C serves as the base for the CDR 108 C mid/high unit. A special coating protects the loudspeakers against dirt and moisture. A dolly with 80 mm casters and butterfly latches is factory-included.
