Eastern Acoustic Works’ Product Usage Guide:
An Introduction
This is the sixth installment in the Eastern Acoustic Works
Product Usage Guide series. The goal of this series is to offer
concise, accurate guidance on the use EAW loudspeaker
products.
Each guide will offer a concise overview of a particular
product series and illustrate the most common methods of
use. Complementary systems, such as subwoofers, will be
recommended for each system and the appropriate MX
Series Close Coupled Processor configuration for each
combination will be discussed.
This chapter will focus on the MQ Series of dedicated
mid/high and low frequency VA 4 loudspeaker systems.
MQ Series Systems
The MQ Series of loudspeakers are specifically designed for
high-performance in permanent installations. This guide
will explain some of the performance features and capabili-
ties and show how MQ Series loudspeakers can be used in a
variety of different ways.
MQ Series Background and Description
The MQ Series comprises an integrated set of biamplified
two-way mid/high frequency modules and low frequency
modules optimized to array with them in specific combina-
tions. The MQ Series is intended exclusively for permanent
installations. Each mid/high module uses one or two horn-
loaded VA
4 10-in mid cone/radial phase plug assemblies and
a 2-in exit/75mm horn-loaded HF compression driver.
Horn-loading of the mid and high frequency drivers allows
the MQ Series modules to maintain accurate pattern control
over their operating bandwidths. This lets the modules array
with minimal interference and makes them suitable for a
variety of applications where fidelity, control and high
output are required. Beamwidth vs. Frequency charts are
presented in the appendix to this Application Guide.
The MQ Series mid/high modules offer a variety of
horizontal and vertical dispersion patterns. Table 1 below
summarizes the primary specifications.
