  • High peak power output with exceptional linearity and transient reproduction at any operating level
  • Self-powered for simplified setup and increased reliability
  • Medium- to large-scale applications
  • Arenas, performing arts centres, theatres, churches, and other fixed installations
  • Touring sound reinforcement
  • Downfill, midfill, sidefill, and outfill for LEO-M systems


The self-powered LYON linear line array loudspeaker is a member of Meyer Sound’s LEO Family of linear loudspeakers, designed to reproduce audio faithfully with tremendous power and clarity, without colouring the sound, even when pushed to the limit. LYON delivers the same headroom and precision as the acclaimed LEO-M with the same cutting-edge technology housed in a lighter and more compact cabinet. Optimized rigging and self-powered configuration streamlines both setup and breakdown for LYON systems. LYON is ideal for medium- to large-scale array applications that do not require the extreme long-throw capability of LEO-M.

For greater flexibility, LYON is available in two models: LYON-M for primary array coverage and LYON-W for wide coverage. LYON-W can be used wherever wide coverage is needed in LYON arrays, at the bottom or in the middle of primary arrays, or even at the top of outfill arrays. Because LYON-W matches the acoustical characteristics and vertical coverage of LYON-M, transitions for horizontal coverage are seamless. Both LYON models are matched acoustically to LEO-M and can be used for downfill and midfill at the bottom of LEO-M arrays, and as supplemental sidefill and outfill arrays in LEO-M systems.

LYON arrays are ideally paired with Meyer Sound’s 1100-LFC low-frequency control element for bass reproduction. Entire systems are driven by Meyer Sound’s Galileo Callisto 616 array processor, which provides matrix routing, alignment, and processing for array components. To guarantee optimum system performance, including coverage patterns and maximum peak SPL, LYON systems should be designed with Meyer Sound’s MAPP Online XT™ acoustical prediction software.

LYON’s high-frequency section is comprised of 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 onboard power amplifier operates at nominal voltages from 85–134 V AC and 165–264 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. The amplifier, control electronics, and power supply are contained in a single field-replaceable module located on the rear of the cabinet.

Meyer Sound’s RMS remote monitoring system comes standard with all LYON 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. XLR 3-pin audio connectors are also available.

LYON offers intuitive rigging with captive Guide-A-Links that can be set to the desired splay angles while cabinets rest in caster frames. The MTG-LYON top grid flies’ arrays of up to 18 LYONs at a 7:1 safety factor (with some restrictions). The optional MTF-LEO/LYON transition frame flies LYONs at the bottom of LEO-M arrays. Stacks of up to four LYON cabinets can be securely transported with the optional MCF-LYON caster frame; durable nylon covers, accommodating stacks of two, three, or four units, are available to protect the cabinets during transport.

The LYON cabinet is constructed of multi-ply hardwood and coated with a black-textured finish. A hex-stamped, steel grille with acoustical black mesh protects the unit’s drivers. Other options include weather protection and custom colour finishes for fixed installations and applications with specific cosmetic requirements.
