KU44W Rumble 4×4 Slim Passive Sub Black
The KU44W line array elements an extremely compact array-able bass element designed to combine with mid-high speakers to provide a full range frequency response with prodigious output in a virtually invisible profile.
The line source sub 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 KU44W allows the user to choose between two different values of impedance: 8/32 Ω. At 32 Ω as many as eight KU44W can be powered off a single KA84 amplifier channel.
KU44W 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. The impregnable frame cannot be penetrated by foreign objects like dust sand or water which over time can damage an ordinary audio element. A variety of dedicated hardware accessories provide architects with numerous mounting options for permanent and portable installations best suited for theatres and other venues where invisible line arrays are ideal.
Installing a line array of KU44W 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.
All KU44W components are designed by the K-array R&D department and custom made under the K-array quality control system.
