The CQ™ Series self-powered loudspeakers contain
independent amplifier and control electronics for one
15” bass-reflex cone driver and one 4” diaphragm horn
driver in a compact enclosure. This integrated design
eliminates amplifier racks, simplifies setup and
installation, and improves durability and reliability.
The CQ Series, consisting of the CQ-1 (low Q) and
CQ-2 (high Q), are efficient full-range speakers and
ideal companions for the PSW-2, PSW-4, and 650-P
self-powered subwoofers. The CQ Series have the
following acoustical specifications:
Frequency Response ±4 dB 40 Hz – 18 kHz
Phase Response ±90° 50 Hz – 16 kHz
Max Peak SPL at 1 m CQ-1: 136 dB; CQ-2: 139 dB
Dynamic Range > 110 dB
The CQ is phase-corrected through the crossover, which
yields exceptional system impulse response and
accurate signal reproduction.
The beam width of a horn is the angle at which the
sound pressure at a given frequency decreases to half
(–6 dB) its on-axis value. Most horns have a beam width
that varies with respect to frequency, nonuniform
frequency response within their coverage area, and
significant side lobes outside their beam width. These
undesirable characteristics are easily identified by
viewing polar patterns plotted at various frequencies.
Meyer Sound developed the CQ Series horns in an
anechoic chamber by measuring coverage patterns
using angular and frequency resolutions of 1° and
1
⁄24 octave, respectively. The CQ Series horns exhibit
Constant Q: the beam width remains consistent across
the horn’s operating frequency range in both the vertical
and horizontal planes. The CQ-1 has a wider horizontal
beam width than the CQ-2. The CQ Series have the
same vertical beam width and share the following
remarkable attributes:
• uniform frequency response within the beam width
• rapid and uniform amplitude attenuation for all
frequencies outside the beam width
• minimal side lobes
The CQ horns are an unprecedented development in
acoustical measurement, design, and manufacturing.
The CQ Series loudspeakers are ideally suited for venues
requiring precise coverage with minimal interaction
between subsystems but are appropriate for any
acoustical environment.
The CQ can be equipped to operate with the Remote
Monitoring System™ (RMS) interface network and
software application. RMS displays signal and power
levels, driver and cooling fan status, limiter activity, and
amplifier temperature for all speakers in the network on
a Windows-based PC.
