The KU210 is an ultra thin, high performance passive subwoofer designed to be the perfect companion 
to any of the K-array Installed Sound Series. A combination of extended frequency response with 
prodigious output and a virtually invisible profile make the KU210 an ideal fit even the most ambitious 
projects. 

The Subwoofer is comprised of a 10” neodymium transducer, combined with a 10” passive transducers, 
instead of a reflex, which ensures that the device remains completely sealed. The unit is engineered for 
maximum linear excursion and minimum residual noise. Its neodymium transducer has a double voice 
coil  to allow for selectable impedence settings allowing you to combine up to 4 KU210s powered by 
just one channel of the KA84 amplifier. 

KU210 is made entirely of steel, making it extremely resistant, even when deployed outside in tough 
weather conditions. This makes it ideal for marine environments where ordinary bass speakers would 
corrode. It cannot be penetrated by foreign objects such as dust, sand or water, which over time can ruin 
a speaker. KA series amplifiers have presets specifically optimized for KU210 applications. 

All KU210 components are designed by the K-array R&D department and custom made under the K-array 
quality control system.
