EX1.2 USER GUIDE P. 4
Acoustic Components
The EX1.2’s woofer technology is based around high
eciency, high power woofer designs. The device
features: 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 acous-
tic loading inside the EX1.2 chambers. The EX1.2 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
There are four industrial grade, internal braces two
placed at the top and two at the bottom 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 exibility. There
is also a standard 33mm pole mount “top hat”
located on the top side of the cabinet.

AC POWER
The EX1.2 is an advanced self-powered loudspeaker
system with on-board amplication and control
systems. Understanding power distribution, voltage
and current requirements, as well as electrical safety
issues, is critical to the safe operation of the EX1.2.

Voltage Requirements
The EX1.2 operates safely and without audio disconti-

window of 100V÷120V in 115V mode and 205V÷250V
when working in 230V mode, at 50 or 60Hz.
If the voltage drops below the low boundary of its safe
operating range, the loudspeaker will shut down if the
voltage does not rise above the low boundary before
storage circuits are depleted. How long the loud-
speaker will continue to function during brownout
depends on the amount of voltage drop and the audio
source level during the drop.
If the voltage increases above the upper boundary of
the range, the power supply can be damaged.
