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 impedance settings allowing you to combine up to four 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 suitable 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.
