Bose Panaray MA12EX – Modular Line Array Loudspeaker, White

Product Overview

The Bose Panaray MA12EX White (SKU 317302-0200) is the white-finish variant of the full-range modular columnar array loudspeaker engineered for demanding speech intelligibility applications in commercial and institutional environments. Its Articulated Array design delivers 160° wide horizontal coverage with 20° nominal vertical control per module — a pattern suited to conference rooms, houses of worship, government spaces, and auditoriums where wide horizontal throw and controlled vertical directivity are required. The white powder-coated aluminum enclosure blends with light-colored walls, ceilings, and architectural trim in modern interior spaces. Performance specifications are identical to the black (317302-0100) version.

Product Description

The MA12EX is built around twelve 2.25-inch high-excursion, weather-resistant full-range drivers arranged in a vertical Articulated Array. This geometry provides wide, consistent horizontal coverage down the length of a room while maintaining narrow vertical control that reduces floor and ceiling reflections — a critical factor in spaces with hard surfaces and reverberant acoustic conditions. Modular stacking allows multiple enclosures to be combined vertically to increase effective throw distance and further tighten vertical pattern control for longer spaces.

Frequency response extends from 75 Hz (±3 dB) to 13 kHz, with usable output down to 58 Hz (−10 dB), providing full-range speech and light music reproduction without a dedicated subwoofer in most mid-size rooms. Sensitivity is rated at 87 dB-SPL (1 W / 1 m), and maximum calculated SPL reaches 112 dB (118 dB peak). The 150 W continuous power handling (600 W peak) scales to 300 W continuous in speech-only operation (155 Hz to 12 kHz).

Two parallel-wired NL4 Speakon connectors and two-conductor barrier strips support through-wiring in multi-cabinet line arrays. Six rear M6 threaded inserts accommodate standard Bose Professional single, double, or triple-stack mounting brackets. The IPX5 weather-resistant rating per IEC 529 extends the MA12EX’s application range to covered outdoor environments. Active loudspeaker EQ and a high-pass filter at 65 Hz are required for optimal performance. An optional CVT-MA12EX transformer enables use on 70V or 100V constant-voltage distribution systems. Available from Creation Networks at a reduced price from the original $2,004.00 list.

Key Features

• 12 High-Excursion 2.25-in Drivers — Weather-resistant drivers in a vertical line array; series/parallel wired to 8 Ω nominal impedance.
• Modular Stacking — Vertical stacking of multiple modules increases throw and reduces floor/ceiling reflections in long or reverberant rooms.
• Full-Range to 58 Hz — Usable output from 58 Hz supports speech and light music without a subwoofer in most installations.
• 150 W Continuous / 600 W Peak — 300 W continuous in speech-only mode; PTC/lamp overload protection.
• 112 dB Max SPL @ 1 m — Calculated from 87 dB sensitivity and rated power handling.
• IPX5 Weather Resistance — Suitable for covered outdoor applications per IEC 529.
• Dual NL4 Speakon + Barrier Strip — Parallel-wired through-connection for multi-cabinet array installations.
• White Powder-Coated Finish — Extruded aluminum sidewalls and zinc-plated steel endcaps; integrates with light-colored architectural interiors.
• Optional 70V/100V Transformer — CVT-MA12EX constant voltage transformer available for high-impedance distribution systems.

Technical Specifications

Frequently Asked Questions

What is the difference between the black (317302-0100) and white (317302-0200) MA12EX?

The only difference is the enclosure finish. Black (317302-0100) uses a black powder-coat; white (317302-0200) uses a white powder-coat. All acoustic and electrical specifications are identical.

How many MA12EX modules should I stack for a large auditorium?

The required number depends on room dimensions, throw distance, and target SPL. Bose Professional’s free Modeler software provides accurate acoustic prediction for MA12EX arrays. Two-module stacks cover most medium spaces; three or four modules address longer throws in larger auditoriums.

Does the MA12EX require active EQ?

Yes. Loudspeaker EQ (active equalization) and a high-pass filter at 65 Hz are required for full-range performance. Bose Professional ControlSpace EX amplifiers and processors include matching presets. Third-party DSP can be configured with the appropriate EQ curve.

Is the MA12EX suitable for outdoor installation?

The MA12EX is rated IPX5 per IEC 529, suitable for covered outdoor environments. It is not rated for direct rain or submerged exposure. For fully exposed outdoor use, consult a Bose Professional dealer about alternative enclosures.

Can the MA12EX operate on a 70V or 100V constant-voltage system?

Yes, with the optional CVT-MA12EX constant voltage transformer. Without the transformer, the MA12EX operates at 8 Ω nominal impedance on standard low-impedance amplifier outputs.

What is the warranty period?

Bose Professional loudspeakers carry a limited warranty. Contact Creation Networks for warranty details and commercial installation support.
