Engineers’ and Architects’
Specifications
The loudspeaker shall be a multiple driver,
full-range system with matched active
equalization as follows:
The transducer complement shall consist of
twelve 2.25" (57mm) high-excursion, weather-
resistant drivers mounted in an Articulated Array
®
loudspeaker design. Each driver shall have a rated
impedance of 5g and wired in series/parallel,
resulting in a composite nominal impedance
of 8
g.
The nominal horizontal beamwidth of the
loudspeaker shall be 160°, and the vertical
coverage is a band of constant height. The
power handling capacity of the loudspeaker
shall be 150W continuous pink noise, band –
limited from 75 Hz to 13 kHz (-3 dB).
The loudspeaker shall be provided with a ducted
vent system, tuned at 75 Hz. The input connector
of the loudspeaker module shall consist of two
parallel-wired Speakon
®
NL4 receptacles and
two two-conductor barrier strips.
The enclosure of the MA12EX speaker module
shall be aluminum. Its outer dimensions shall
be 38.8" H x 4.1" W x 5.5"D (986mm x 104mm
x 140mm). Its weight shall be 20.8lbs.
The loudspeaker shall be the Bose

MA12EX modular line array loudspeaker.
Safety and Regulatory Compliance
The MA12EX loudspeaker complies with
ANSI/EIA-636 Recommended Loudspeaker
Safety Practices.
Rigging
MA12EX loudspeakers can be mounted as a
single element or stacked in multiples to achieve
line array performance. Bose MA12EX loudspeaker
mounting brackets are available and tested for
use with single-, double- and triple-stack MA12EX
loudspeaker installations. For installations of four
or mor
e MA12EX loudspeakers, obtain your
mounting system from a reputable manufacturer.
Select a system design that works for your loud-
speaker of choice and its intended use. Always
have a licensed professional engineer review the
design and fabrication for structural integrity and
safety in the intended application.
How our Loudspeakers
are Measured
1. Frequency Response and Range
Data is the average response in the typical
coverage area with the recommended
equalization applied.
2. Calculated Max SPL
Calculated based on input sensitivity with
recommended equalization applied and
maximum input power rating exclusive of
power compression.
3. Input Power Rating
Pink noise with a 6 dB crest factor is bandpass
limited to the operating range of the
loudspeaker and applied for 100 hours.
4. Axial Sensitivity
Full-bandwidth pink noise with recommended
equalization amplified to a level of 1 watt and
applied to the loudspeaker in an anechoic
environment.
