The Rumble-KU26, the smallest sub in our portfolio, is an extremely powerful, bass system comprised of one 6” neodymium transducer and one 6” passive radiator engineered for maximum linear excursion and minimum residual noise. With a frequency range of 45 Hz to 150 Hz, the Rumble-KU26 is a companion to our Lyzard, Vyper, Tornado and Anakonda speakers. The combination provides full-range frequency response with prodigious output in a virtually invisible profile.

The Rumble-KU26 boasts extended frequency response and is electronically protected. Its neodymium transducer has a dual voice coil (16+16 Ω) for selectable impedance settings (8/32 Ω) allowing you to combine up to eight Rumble-KU26 units powered by just one Kommander-KA84 amplifier channel.
