DESCRIPTION
• The Rumble-KU210 is an ultra-thin, high performance passive subwoofer designed to be the perfect companion to 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 solution even for 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 for two selectable impedance 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.
