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) cov-
erage 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.

Typical Subwoofer Energy Dispersion
Most subwoofers radiate energy around the entire enclosure, leading to
undesirable LF build-up on stage and wasted energy around the sides
and rear of the system.
Cardioid Subwoofer Energy Dispersion
The KS212C keeps “Bass in its Place” with a single-box cardioid
array that produces an amazing 15 dB more output at the front than at
the rear.
