The Problem
Typically, subwoofers are omnidirectional, radiating sound equally in all directions. This results in troublesome, unwanted low-frequency build-up on stage as well as undesired, wasted LF energy at the rear of the system. In more recent years, concert sound providers have been able to create cardioid (heart-shaped) coverage of their subwoofer arrays through some clever manipulation of placement, delay and polarity, redirecting desired LF energy forward and minimizing energy at the sides and rear. Un- fortunately, this technique is costly and requires multiple enclosures, amplifiers and processors.
The KS212C Solution
Representing a breakthrough in innovation and design, the KS212C uniquely provides all the benefits of a cardioid subwoofer array, but in a single, compact enclosure. “Keeping bass in its place” for mobile entertainers, AV production and rental professionals, as well as modestly-sized performance venues, the KS212C is unparalleled in its ability to manage low frequencies on the stage, or any application where undesirable low frequency energy needs to be minimized.
