K-array launches thin subwoofer for Slim Array9 February 2016
A thin subwoofer has been launched to complement the Slim Array Technology incorporated in K-array’s speakers.
The company claims the KU44 line array element is an extremely compact, array-suitable, bass element, designed to combine with mid-high speakers to provide a full range frequency response with high output in a ‘virtually invisible’ profile.
The line source sub has a frequency range of 50Hz to 150Hz and is comprised of two 4in Neodymium transducers and two 4in passive radiators, which the company says are 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 or 32 ohms. At 32 ohms, as many as eight KU44 units can be powered off a single KA amplifier channel.
KU44 is made entirely of steel, increasing its resistance even when deployed outside in tough weather conditions. K-array says this makes it ideal for waterfront environments where ordinary bass speakers would corrode. It is also said to be impregnable from foreign particles 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.
