Meyer Sound’s LEO-M full-size powered line-array system is a large-scale sound-reinforcement system known for providing ultra-high-quality audio to large venues like stadiums, arenas, and more. Each LEO cabinet contains two 15-inch low-frequency drivers and four 4-inch high-frequency compression drivers, creating an operating frequency range of 55Hz–16kHz.
The Meyer LEO System includes the LEO-M full-size line array, LYON compact line array, 1100-LFC subwoofer, Galileo GALAXY Network Platform, MDM-5000 Distribution Module, and associated rigging equipment. The LEO System has been used to reinforce concerts as diverse as the New York Philharmonic, Shania Twain, Marc Anthony, Metallica, and Ed Sheeran. The LEO family of products is also installed at Ford Field, the home stadium of the Detroit Lions.

From the Manufacturer
Sonic linearity at any output level defines the LEO®‑M advanced linear array loudspeaker. Conceived for long-throw applications, with exceptional headroom, extremely low distortion, and optimized rigging options, LEO‑M forms the nucleus of Meyer Sound’s next‑generation LEO array systems. Pair LEO arrays with Meyer Sound’s 1100‑LFC low-frequency control element for bass reproduction, and the LYON® linear line array loudspeaker for downfill. Drive entire systems with Meyer Sound’s Galileo® GALAXY Network Platform, which provides 24-bit, 96 kHz audio, matrix routing, alignment, and processing for array components.
To guarantee optimum system performance, design LEO array systems with Meyer Sound’s MAPP™ System Design Tool. This intuitive, cross-platform application accurately predicts coverage patterns, frequency and impulse responses, and linear peak SPL for LEO array systems, ensuring that systems deliver the required SPL and ideal coverage for the intended audience areas.
LEO‑M’s high-frequency section comprises two proprietary compression drivers coupled to a constant-directivity horn through a patented REM® manifold. The manifold’s smooth radiating characteristics afford tight vertical coverage. The low‑frequency section includes two long-excursion cone drivers, also proprietary, capable of withstanding high continuous output levels. Precise phase and magnitude alignment between low‑ and high-frequency drivers yields consistent and well‑behaved system responses.
The unit’s power amplifier operates at nominal voltages from 208—235 V AC at 50—60 Hz. TruPower® limiting ensures maximum driver protection, minimizing power compression while yielding high constant output under high continuous and peak power conditions. A single field-replaceable module located on the rear of the cabinet contains the amplifier, control electronics, and power supply.
Meyer Sound’s RMS™ remote monitoring system comes standard with all LEO‑M loudspeakers and provides comprehensive monitoring of system parameters on a Mac® or Windows®-based computer. Convenient XLR 5-pin connectors allow the use of composite cables carrying both RMS and balanced audio.
LEO‑M offers intuitive rigging with captive GuideALinks™ that users can set to the desired splay angles while cabinets rest in caster frames. The MTG‑LEO‑M top grid flies arrays of up to 22 LEO‑Ms at a 5:1 safety factor (with some restrictions). Fly LYONs below LEO‑M arrays for downfill with available optional transition frames. Securely transport stacks of up to four LEO‑Ms with the optional MCF‑LEO‑M caster frame; Protect the cabinets during transport with optional durable nylon covers that accommodate stacks of two, three, or four units.
Meyer Sound builds the vented LEO‑M cabinet with premium multi‑ply birch and coats it with a slightly textured black finish. A powder-coated, hex‑stamped steel grille with acoustical black mesh protects the unit’s drivers. The weather-protected cabinet and included collapsible rain hood that shields user panel connectors from water intrusion accommodate a variety of applications.
