Panaray® MA12EX
full-range modular line array
Key Features
• Twelve 2.25" (64 mm) full-range drivers mounted in a vertical line array
deliver wide horizontal coverage with narrow vertical pattern control
• Modular design allows stacking of multiple enclosures in a line
array configuration to provide increased vertical pattern control which
improves “throw” distance and reduces unwanted floor/ceiling reflections
• Articulated Array® design provides wide 160° horizontal coverage
with 20° nominal vertical coverage for a single module. Actual vertical
coverage varies with number of modules in line array configuration
• Frequency range down to 58 Hz allows full-range speech and light
music reinforcement without separate low-frequency loudspeakers. For
extended bass and higher output levels, use with Bose MB4, MB12, or
MB24 modular bass loudspeakers
• Optional brackets allow easy installation of single-, double- or triple-
stack line array modules
Product Overview
The Bose® Panaray® MA12EX is a full-range modular line array loudspeaker designed to provide outstanding vocal intelligibility in
acoustically demanding spaces. The slim column enclosure blends with almost any décor. The "EX" version adds an Articulated Array
design to provide wider 160° horizontal coverage and weather-resistant components to allow outdoor applications.

Footnotes:
1 Frequency response and range measured on-axis with recommended active EQ in an anechoic environment.
2 Vertical coverage varies by number of modules vertically arrayed and distance from line-source boundary. Use Modeler® software for the best prediction.
3 Power handling tested using pink noise filtered to meet IEC 268-5, 6 dB crest factor, 100 hours, with recommended EQ.
4 MA12EX PowerHandling. 150W for full-range music and speech applications. Speech-only applications (155 Hz to 12 kHz), power handling (continuous) at 300W/1200W.
5 Sensitivity measured in free field (no boundary-loading gain) with recommended active EQ, referenced to 1W/1m.
6 Maximum SPL calculated from sensitivity and power handling specifications, exclusive of power compression.

Architects’ and Engineers’
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" (57
mm) high-excursion, weather-resistant drivers mounted in an
Articulated Array® loudspeaker design. Each driver shall have a
rated impedance of 5 ohms and wired in series/parallel, resulting
in a composite nominal impedance of 8 ohms.
The nominal horizontal beamwidth of the loudspeaker shall be
160 degrees, and the vertical coverage is a band of constant
height. The power handling capacity of the loudspeaker shall be
150 watts 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 NL4 Neutrik
Speakon® connectors and two (2) two-conductor barrier strips.
The enclosure of the MA12EX speaker module shall be
aluminum. Its outer dimensions shall be 38.8" x 4.1" x 5.5" (985
mm x 104 mm x 139 mm). Its weight shall be 21 lb (9.4 kg).
The loudspeaker shall be the Bose® Panaray® MA12EX modular
line array loudspeaker.
