Applications

  • Houses of worship
  • Multi-purpose spaces
  • Recreation
  • Restaurants and bars
  • Auditoriums
  • Transportation facilities
  • Gymnasiums
  • Atriums and malls

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

Footnotes:

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

 

Architects' & 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.
