The Rumble-KU210 subwoofer is a high-power passive sub featuring a 10” neodymium transducer an a 10” passive transducer in an ultra-shallow box. Rather than reflex openings, the KU210 features a passive radiator that ensures the device remains completely sealed off from foreign objects.

The Rumble-KU210 is engineered for maximum linear excursion and minimum residual noise. Its neodymium transducer has a double voice coil for two selectable impedance settings 4/16 Ω (2 x 8Ω) to allow a combination of up to 4 units powered by just one channel of the Kommander-KA84 amplifier.
