Description
The QRx-212H/75 is two-way, full-range loudspeaker
system incorporating two 12-inch woofers and a 3-inch
voice coil compression driver on an asymmetrical 75-
degree x 50-degree fully rotatable constant-directivity
horn. In factory delivered position when used
horizontal, this provides a 15-degree up/35-degree
down vertical coverage pattern. The multi-angle
cabinet design allows this system to easily conform to
limited space clearances. The fully rotatable horn
allows optimal coverage regardless of cabinet position.
The configuration of horn in the center of two LF
transducers each driven by different frequencies
provides smooth horizontal coverage. The
QRx-212H/75 is a good solution for medium size
rooms and audiences as a main PA providing moderate
levels with good bass response and added punch in
the lower and mid frequencies, satisfying most DJ and
live band applications. The asymmetrical horn can
allow a single box to direct the high frequencies as
needed, as well as streamline multi-cabinet arrays
when rotated by extending horizontal coverage while
minimizing overlapping and allowing tighter packs
between the cabinets. The small height requirement
makes it ideal for dance floor installations. The
addition of the QRx118 or QRx218 subwoofer
completes the perfect high level dance rig. The M212
processing module for EV’s Modular Precision Series
Amplifiers Provides optimized processing for full-range
use, or in any combination with QRx subwoofers.
