Our Thunder line gives you all the boom with bass you need for installation applications. With both passive and active models in various sizes starting from 12" to 21" and dual 18", the Thunder line is a high performance subbass system featuring a woofer with magnet structure and suspension engineered for maximum linear excursion. Pocket handles and an M20 thread mount position for attaching mid-high speakers make the subwoofers convenient to use and ideal for applications in theaters, concert halls, and restaurant installations. More than just powered subwoofers, our active models depart from traditional subs in that their "smart" design puts electronics as the central component, transforming the mid-low frequency loudspeaker into a proper tool for the management and processing of the audio signal. The Thunder-KS self powered subwoofers implement a 4-channel power amplifier module with built-in DSP that can be managed and controlled via the dedicated K-array Connect app or the K-framework3 software.
