Bose Panaray MA12EX – Modular Line Array Loudspeaker, Black

Product Overview

The Bose Panaray MA12EX is a full-range modular columnar array loudspeaker engineered for high intelligibility in acoustically demanding commercial and institutional spaces. Twelve 2.25-inch high-excursion drivers deliver the MA12EX’s 160° wide horizontal coverage with 20° nominal vertical pattern control — a configuration that maximizes direct-to-reverberant ratio in large conference rooms, auditoriums, houses of worship, and government spaces. The “EX” designation adds Bose’s Articulated Array design and weather-resistant driver construction, extending the MA12EX’s application range to covered outdoor environments. The black powder-coated aluminum enclosure (SKU 317302-0100) integrates into dark-trimmed architectural interiors without visual disruption.

Product Description

The MA12EX measures 985 × 104 × 139 mm and weighs 9.4 kg, occupying a slim vertical footprint suitable for wall mounting at column positions, flanking a projection screen, or deploying as a floor-standing monitor in broadcast applications. Its modular design supports stacking multiple enclosures vertically to extend throw distance and tighten vertical pattern control — a technique used in auditoriums and long reverberant spaces to reduce floor and ceiling reflections.

Frequency response extends from 75 Hz (±3 dB) to 13 kHz, with usable range down to 58 Hz (∓10 dB), enabling full-range speech and light music reinforcement without a separate subwoofer in most installed configurations. For extended bass response, the MA12EX pairs with Bose Professional MB4, MB12, or MB24 modular bass loudspeakers. Power handling is 150 W continuous (600 W peak) with sensitivity rated at 87 dB-SPL (1 W / 1 m), yielding a calculated maximum SPL of 112 dB (118 dB peak) at 1 m — sufficient for medium to large room coverage in most commercial and institutional applications.

Two parallel-wired NL4 Speakon connectors and two-conductor barrier strips allow through-connection for multi-cabinet arrays. Six M6 threaded inserts on the rear facilitate bracket mounting via standard Bose Professional mounting hardware. A recommended high-pass filter at 65 Hz and active EQ are required for optimal performance. The extruded-aluminum sidewalls with zinc-plated steel endcaps carry an IPX5 weather-resistant rating per IEC 529, supporting covered outdoor installations. Available from Creation Networks at a reduced price from the original $2,004.00 list price.

Key Features

• Articulated Array Design — 160° horizontal × 20° vertical nominal coverage per module; actual vertical coverage narrows when modules are stacked vertically.
• 12 High-Excursion 2.25-in Drivers — Weather-resistant full-range drivers mounted in a vertical line array for consistent horizontal coverage and controlled vertical directivity.
• Modular Stacking — Multiple enclosures stack vertically to increase throw and reduce floor/ceiling reflections in long or reverberant spaces.
• Full-Range Performance to 58 Hz — Usable frequency range extends to 58 Hz (−10 dB), supporting speech and light music without a separate subwoofer in most rooms.
• 150 W Continuous / 600 W Peak Power Handling — Handles 300 W continuous in speech-only applications (155 Hz to 12 kHz).
• 112 dB Max SPL @ 1 m — 87 dB sensitivity; 118 dB peak SPL calculated from sensitivity and power handling.
• IPX5 Weather Resistance — Rated for covered outdoor use per IEC 529; weather-resistant driver components throughout.
• Dual NL4 Speakon + Barrier Strip Connectors — Through-connection for multi-cabinet array wiring.
• Extruded Aluminum / Zinc Steel Enclosure — Powder-coated black finish; 985 × 104 × 139 mm; 9.4 kg.
• Optional CVT-MA12EX Transformer — 70V/100V constant voltage transformer available for high-impedance distribution systems.

Frequently Asked Questions

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

The required number of modules depends on room dimensions, throw distance, and target SPL. Bose Professional’s free Modeler software provides accurate acoustic prediction for MA12EX arrays. As a general guide, two-module arrays are common in medium spaces (up to ~15 m throw), while three or four modules are used for longer throws in larger auditoriums.

Does the MA12EX require an amplifier with specific EQ?

Yes. The MA12EX requires loudspeaker EQ (active equalization) and a recommended high-pass filter at 65 Hz for full-range performance. Bose Professional ControlSpace EX amplifiers and processors include appropriate presets. Third-party DSP amplifiers can be used with manual EQ configuration.

Is the MA12EX suitable for outdoor use?

The MA12EX carries an IPX5 weather-resistant rating per IEC 529, making it suitable for covered outdoor applications such as covered patios, outdoor worship areas, and covered stadium concourses. It is not rated for direct rain exposure.

Can the MA12EX be used on a 70V or 100V distribution system?

Yes, with the optional CVT-MA12EX constant voltage transformer accessory. Without the transformer, the MA12EX operates as a standard 8 Ω low-impedance loudspeaker.

What brackets are available for the MA12EX?

Bose Professional offers optional mounting brackets for single, double, and triple-stack line array configurations. Bracket part numbers and load ratings are available from Creation Networks.

What is the warranty period?

Bose Professional loudspeakers carry a limited warranty. Contact Creation Networks for current warranty terms applicable to commercial installations.
