Rumble-KU44

The Rumble-KU44 line array element is an extremely compact, array-able subwoofer with a frequency range of 50 Hz to 150Hz and is comprised of two 4” neodymium transducers and two 4” passive radiators engineered for maximum linear excursion and minimum residual noise.

For easier use and integration with all Kommander amplifiers, the KU44 allows the user to choose between two different values of impedance (8/32 Ω). At 32 Ω, as many as eight KU44 units can be powered off a single Kommander amplifier channel.
