CHAPTER 1: INTRODUCTION

Designed specifically for cinema, the Acheron horn features
a very soft roll-off beyond its 80-degree horizontal by 50-
degree vertical coverage pattern. The extremely well-
behaved horn ensures an accurate acoustic crossover and
consistent vertical coverage pattern through the critical
crossover range between the low- and high-frequency driv-
ers. The optimized crossover point places most of the dialog
in the horn, which is ideal for cinema applications.
Designed and manufactured at Meyer Sound's headquar-
ters in Berkeley, California, the Acheron Designer’s drivers
include one 12-inch low-frequency cone driver, housed in an
optimally tuned, ported enclosure, and one high-frequency
4-inch diaphragm compression driver. The drivers yield
uncompromising quality and are powered by sophisticated
onboard amplification. The self-powered design ensures
consistent results and simplifies installations in both new
and existing rooms.
A proprietary two-channel, Class-D amplifier powers each
driver channel independently. Onboard processing includes
driver protection circuitry, an electronic crossover, and cor-
rection filters, ensuring flat frequency and phase responses.
The rear-mounted, recessed heat sink yields efficient con-
vection cooling, and allows the unit to be placed flat against
walls, when necessary.
The optional RMS™ remote monitoring system provides
comprehensive monitoring of system parameters on a
Windows
®
-based computer.
The Acheron Designer enclosure is constructed of premium
birch plywood and coated with a low-gloss, black-textured
finish. The cabinet bottom is fitted with two threaded M6
attachment points for the optional MYA-DES cradle-style
yoke, allowing the unit to be suspended from a single hang-
ing point.
An optional, black cloth grille frame update kit is available
for installations where the Acheron Designer is not placed
behind a screen.
