you against improper or potentially harmful activities.
The EX1.2 can be used in a variety of system applica-
tions. This low prole design makes it a fantastic choice
for discreet installations as it can be installed both
horizontally or vertically. It can add high performance
bass reproduction to active speaker systems such as
KV2 Audio’s EX10 loudspeaker, or it can be easily used
with passive speaker systems. The built in electronic
high pass lter, phase and independent output level
controls provide high precision, easy to use system
integration circuitry.
Electronics
Amplier power, electronic crossovers, equalization
and speaker protection are integrated into the EX1.2’s
amplier module. On-board electronics ensures fast,
easy set up and complete control making it easy to set
up and provides long-term reliability. An improved
version of KV2 Audio’s switch mode, current enhancing
low frequency amplier has been specially developed
for the EX1.2 . The new design improves overall system
eciency to over 90% and delivers 500 watts of
continuous power.
KV2 Audio has developed an amplier topology that
possesses two unique characteristics that are critically
important for high performance, active subwoofer
systems. The EX1.2 amplier topology delivers very
high eciency and generates minimal thermal losses
allowing the amplier to deliver extremely high power
levels reliably whilst employing a simple cooling
system.
Secondly, in order to reproduce low frequency infor-
mation with high transient content and extend the
operational boundaries of the acoustic design, the
amplier needs to deliver an extraordinary amount of
current in order to keep the woofer’s high mass under
control. This is especially true under typical “phase
shift” conditions, in which the amount of the current
requirement is sometimes doubled. Through the
implementation of a proprietary, switch mode ampli-
er technology, the EX1.2 amplier provides extremely
high eciency with low losses and delivers the highest
woofer control by delivering higher current levels
under “phase shift” conditions.
Introducing the EX1.2
The EX1.2 is a incredibly compact size, active
subwoofer system. Through the use of proprietary
amplier technology, a precision manufactured state
of the art woofer component and the innovative
implementation of a high eciency, twin chamber
acoustic design, the EX1.2 delivers tight, fast, control-
led bass response at high output levels. This system
falls directly out of KV2 Audio’s philosophy to develop
products with increased dynamic range, high output
and a consistent sound character no matter what the
output level.
The system establishes new performance standards
for an active powered subwoofer that can only be
achieved through the integration of new amplier
topologies, transducer designs and electronic control
technologies that are closely tied to a passion for
taking performance to the next level.
