EX1.8 USER’S GUIDE P. 4
Acoustic Components
The EX1.8’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 EX1.8 chambers. The EX1.8 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 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
exibility. There is also a pole mount “top hat” located
on the top side of the cabinet.

AC POWER
The EX1.8 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 EX 1.8.
