The Rumble-KU44 linearray elementis 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 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
KA84 amplifier channel.
KU44 is made entirely of steel, making it
extremely resistant, even when deployed
outside in tough weather conditions. This is
ideal for acquatic environmen applications
where ordinary bass speakers would
corrode. The imprengnable 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 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.
All KU44 components are designed by the
K-array R&D department and custom made
under the K-array quality control system.
