KU44

1. INTRODUCTION

K-array has created a thin subwoofer to complement its notable Slim Array Technology incorporated in
its speakers. The KU44 line array element is 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 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 KA 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 can be powered off a single
KA amplifier channel.
KU44 is made entirely of 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. It 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 KU44 subwoofers at the side or behind a line array of Kobras allows to create a
full range sound source with true line-array characteristics down to 50 Hz.
All KU44 components are designed by the K-array R&D department and custom made under the K-array
quality control system.
