EX 2.2 ACTIVE BASS MODULE
1000 Watt Dual 12-inch Subwoofer
with current-enhancing Switch Mode technology
The EX 2.2 is a compact, high output active subwoofer
system. Through the use of proprietary amplifier technology, precision
manufactured, high-tech woofer designs and the innovative implementation of
a high efficiency, twin chamber acoustic design, the EX 2.2 delivers tight,
fast, controlled bass response at very high levels. It falls directly out of
KV2 Audio’s philosophy to develop products with increased dynamic range,
very high output and a consistent sound character no matter what the output
level. The system establishes new performance standards for a compact
subwoofer that can only be achieved through the integration of new
amplifier, transducer and electronic control technologies that are closely
tied to a passion for taking performance to the next level.
The EX2.2 is can be used in a variety of system
applications. 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 filter,
phase and independent output level controls provide high precision, easy to
use system integration circuitry.

Electronics
Amplifier power, electronic crossovers, equalization and speaker protection
are integrated into the EX 2.2’s amplifier module. On-board electronics
ensures fast, easy set up, complete control making it easy to set up and
long term reliability. An improved version of KV2 Audio’s switch mode,
current enhancing low frequency amplifier has been specially developed for
the EX 2.2. The new design improves overall system efficiency to over 90%
and delivers 1000 watts of continuous power.
KV2 Audio has developed an amplifier topology that
delivers two unique characteristics that are critically important for high
performance, active subwoofer systems. The EX 2.2 amplifier topology
delivers very high efficiency and generates minimal thermal losses allowing
the amplifier to deliver extremely high power levels reliably and
simplifying the cooling system. Secondly, in order to reproduce low
frequency information with high transient levels and extend the operational
boundaries of the acoustic design, the amplifier needs to deliver an
extraordinary amount of current in order to maintain the woofer under
control. This is especially true under standard “phase shift” conditions in
which the amount of total voltage the amplifier can deliver is limited and
the current requirement is sometimes doubled. Through the implementation of
a unique, switch mode amplifier technology, the EX 2.2 amplifier delivers on
both objectives, providing extremely high efficiency, low losses and
delivering the highest woofer control by delivering higher current levels
under “phase shift” conditions.
The electronics are fitted onto to a large format,
finned, aluminum alloy heat sink providing high flow, passive cooling and
eliminating standard maintenance cycles associated with forced cooled
amplifier designs. The entire mechanical assembly is fitted on a mechanical
suspension system that isolates low frequency energy and ensures long term
reliability.
Acoustic
Components
The EX 2.2’s woofer technology is based around high efficiency woofer
designs. The devices feature, high temperature polymide voice coil
assemblies that undergo multiple baking and curing processes as well as
advanced magnetic structures with complex cooling systems. The woofer cones
have been specially developed to withstand the demanding environment created
by the high loading inside the EX 2.2.
The EX 2.2 was designed using new concepts in twin
asymmetrical acoustic chambers that deliver very high speaker loading and
output from a relatively small cabinet footprint. It is ideal for use in
live applications that require reproduction of low frequencies with very
high transient content at high output levels.
Enclosure
Design
The EX 2.2 is a very compact, lightweight enclosure featuring a number of
ergonomically designed parts that make it an easy system to set up and use.
KV2 designed and tooled a new very compact “side handle” that is recessed
into each side of the cabinet. There are eight custom molded, low friction
feet placed at the bottom and back of the cabinet. Routed “foot” cutouts
allow easy stacking.
There are two industrial grade, internal braces placed
at the top of the cabinet. Each brace is held in place by four M8 bolt and
feature two M10 hang points providing a wide range of installation and
suspension flexibility. There is also a pole mount “top hat” located at the
top of the cabinet.
