Meyer Sound M3D: The Line Array Loudspeaker That Transformed Touring Audio

When the Meyer Sound M3D debuted, it wasn’t just another speaker—it was a revolution in sound reinforcement. As one of Meyer Sound’s first self-powered, high-power line array loudspeakers, the M3D introduced radical innovations that shaped how large-scale concerts and festivals are amplified.

With its patented directional control, twin 15” drivers, and integrated power system, the M3D offered a combination of power, precision, and simplicity never seen before in a line array. Even today, it’s remembered as the box that helped define modern touring sound.

Why the Meyer Sound M3D Was a Game-Changer

Pioneering Directional Control

Meyer introduced Controlled-Coupling Technology™ with the M3D. This system offers unprecedented horizontal pattern control and minimizes side lobes, allowing audio to reach the audience—not the walls or ceiling.

Self-Powered for Efficiency

Forget amp racks and power-hungry chains. The M3D includes multi-channel internal amplification, delivering plug-and-play performance and saving truck space and setup time.

Touring-Grade Construction

From the aluminum front grille to the birch plywood enclosure and integrated rigging, every inch of the M3D is built to endure the rigors of touring while maintaining flawless performance.

Massive Output with Stunning Detail

Pumping out up to 145 dB peak SPL, the M3D is capable of covering stadiums, festivals, and arenas—but with the clarity expected in a studio monitor.

What Made the M3D Unique

• Controlled-Coupling Technology™: Maintains consistent horizontal coverage

• Self-Powered Modules: Reduces cabling and amp racks

• Integrated Rigging: Simplifies stacking and flying in arrays

• Phase-Coherent Design: Maintains intelligibility across long distances

• Smooth System Integration: Designed to pair with Meyer 700-HP, 650-P, and 600-HP subs

Why Engineers Still Trust the M3D

• Predictable performance, gig after gig

• Less setup time due to internal amplification

• Reliable under extreme conditions

• Tight pattern control means fewer room reflections

• Ideal for legacy systems still in operation worldwide

The M3D may not be the latest model, but it’s still one of the most respected in the business.

FAQs About the Meyer Sound M3D

Is the M3D still in production?
No. It’s a legacy product, but it’s still supported and available from authorized dealers and rentals.

What kind of amplifier does it use?
It uses a multi-channel Class AB/H self-powered amplifier system designed specifically for the drivers inside the cabinet.

Can it be used with newer Meyer arrays like LEO?
Not typically. However, it works well within its own ecosystem and with legacy subs like the 650-P, 700-HP, and 600-HP.

Is it suitable for modern installs?
Yes, especially in budget-conscious or legacy-compatible systems that demand high output and wide coverage.

How is the rigging handled?
Each M3D includes integrated rigging hardware for quick and secure flown arrays.

Does it require DSP?
Basic DSP is built-in, but it integrates best with Meyer Galileo processors for full system tuning and control.
