Product Overview

The Bose Professional Panaray MA12 is a modular vertical line-array loudspeaker designed for commercial AV installations where controlled directivity and consistent speech intelligibility are required across large seating areas. The white finish variant (SKU 40188) is the preferred choice for installations in brightly lit spaces, white ceiling environments, and facilities where speaker equipment should blend with the architectural interior rather than stand out. The MA12 is widely deployed in houses of worship, conference rooms with high ceilings, auditoriums, and government facilities.

Product Description

The MA12 column speaker uses twelve 2-inch full-range transducers arranged in a vertical line to produce a precisely controlled dispersion pattern: 25 degrees vertically and 180 degrees horizontally. This combination is fundamental to how the MA12 solves the intelligibility problem in reverberant rooms. The narrow vertical pattern prevents sound energy from reaching ceilings and floors where it would reflect back into the room and create late-arriving echoes that mask speech clarity. The wide horizontal pattern simultaneously ensures even level distribution from left to right across the seating area without requiring additional speaker positions.

The white finish MA12 is acoustically identical to the black variant and is a common specification for worship spaces with white or off-white painted walls, training rooms with white perimeter walls, and corporate environments with clean modern interiors. Multiple MA12 modules can be stacked to increase output SPL for larger spaces, with Bose Professional’s Panaray System Design software available to predict coverage and select the optimal configuration before installation.

At 200 watts continuous and 8 ohms impedance, the MA12 is compatible with a wide range of commercial power amplifiers. The standard NL4 Speakon input connector simplifies wiring to amplifier rack systems. Wall-mount brackets and flown rigging hardware are available for flexible installation configurations across different room types.

Key Features

Frequently Asked Questions

What is the difference between the MA12 white (40188) and the MA12 black (40189)?The two variants are acoustically identical. The only difference is the finish: white (40188) for light-colored room environments and black (40189) for darker installations. Specifications, mounting hardware, and compatibility are the same.How does the MA12 improve speech intelligibility compared to a conventional point-source speaker?The MA12’s narrow 25-degree vertical dispersion pattern directs sound toward the audience and away from floor and ceiling surfaces. This reduces early reflections and reverberation in the listening area, which are the primary causes of reduced STI (Speech Transmission Index) in reverberant rooms such as worship spaces and large conference halls.What amplifier should I use with the MA12 white?The MA12 is rated at 8 ohms and 200W continuous. Bose Professional PowerSpace amplifiers are a natural pairing for integrated ControlSpace system designs. Any commercial power amplifier capable of 200400W into 8 ohms is appropriate.Can the MA12 be used outdoors?The standard MA12 is designed for indoor installation. Bose Professional offers outdoor-rated variants in the Panaray lineup. The standard MA12 should not be permanently installed in exposed outdoor environments.What is the warranty on the Bose Panaray MA12?Bose Professional products carry a limited warranty. Contact Creation Networks at for warranty details and commercial service support.Is Panaray System Design software free?Yes. Bose Professional Panaray System Design software is available as a free download for AV integrators and system designers to model array configurations, coverage patterns, and SPL predictions before installation.
