The Rumble-KU26 is an extremely powerful, bass element comprised of one 6” neodymium magnet woofer and one 6” passive radiator engineered for maximum linear excursion and minimum residual noise. The woofer has a dual voice coil (16+16 Ω) for selectable impedance settings (8/32 Ω) allowing users to combine up to eight KU26 units powered by just one KA84 amplifier channel. KU26 is made entirely of stainless steel, making it extremely resistant, even when deployed outside in tough weather conditions. This is ideal for water-front environments where ordinary bass speakers would corrode. Wall brackets are included while other useful tools are available for purchase, like the flush mount recessing frame, K-WF26, used to further hide the subwoofer.
