K-ARRAY Rumble-KU44 I

The Rumble-KU44 is an extremely compact, arrayable bass element designed to combine with mid-high speakers to provide a full-range frequency response with prodigious output in a virtually invisible profile. This subwoofer has a frequency range of 50 Hz to 150 Hz 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 KA amplifiers, the KU44 allows the user to choose between two different values of impedance, 8/32 Ω. At 32 Ω as many as 8 units can be powered off a single 4Ω amp channel. By recalling the dedicated presets, the K-ARRAY Kommander amplifiers are the best electronics to run any Rumble subwoofer, capable to balance perfectly all the settings you need to match with any mid-high speaker of the K-ARRAY’s catalog. This helps integrators to find their complete solutions in the same range of products.

KU44 is made entirely of steel, making it extremely resistant, even when deployed outside in tough weather conditions. This is ideal for aquatic environment applications where ordinary bass speakers would corrode. On request, the MARINE version features even higher treatments against salt corrosion.

A variety of dedicated hardware accessories provide integrators with numerous mounting options for permanent and portable installations best suited for retail, restaurants, hotels, bars, museums and other environments where invisible line arrays are ideal.
Installing a line array of KU44 subwoofers to the side or behind a line array of Kobras creates a full-range sound source with true line array characteristics down to 50 Hz.
