MILO is a self-powered, four-way loudspeaker designed for vertical curvilinear arraying. It has ample power reserves (140 dB SPL peak output at 1 meter) for high output level, longer throw applications in large venues, yet its weight and cabinet dimensions allow for its use in more compact spaces.

MILO was designed to easily integrate with other Meyer Sound loudspeakers, particularly the M3D™ line array, M3D-Sub directional subwoofer, M2D compact curvilinear array and the CQ-2 full-range narrow coverage loudspeaker. Though substantially smaller than the M3D/M3D-Sub in height and depth, MILO shares the same width for seamless integration. When MILO arrays also include M3D-Subs, the combination exhibits dramaticly attenuated off-axis low-frequency response. This allows system designers to configure arrays that effectively steer bass energy away from areas located behind the arrays, such as the stage and monitor mix position, where minimum levels are desired.

The MILO low/low-mid section comprises two neodymium magnet 12-inch cone drivers with 4-inch voice coils. These drivers function in a two-way arrangement, with both drivers active below 300 Hz for maximum low frequency impact. Above 300 Hz, an integral crossover rolls off one driver to maintain optimal polar and frequency response.

The mid-high section uses a 4-inch diaphragm (1.5-inch exit) compression driver MILO™ : High-Power Curvilinear Array Loudspeaker coupled to a 90° constant directivity horn through Meyer Sound’s REM™ ribbon emulation manifold (patent pending). REM produces a wave front similar to that of a ribbon driver, but allows the far higher output generated by a compression driver. A dedicated very-high frequency section, with extended range to 18 kHz, employs three 2-inch diaphragm (0.75-inch exit) compression drivers coupled via a second REM to a 90° horn.

All MILO transducers are designed and manufactured in-house by Meyer Sound, and are driven by an on-board, four-channel class AB/H amplifier that provides more than 3935 watts of total output power. The integrated amplifier/processing circuitry includes TruPower* limiting to protect the drivers and hold long-term power compression to less than 1 dB. The field-replaceable electronics module incorporates Meyer Sound’s Intelligent AC™ power supply, which automatically adjusts for any line voltage worldwide and provides both soft turn-on and transient protection.

Meyer Sound’s RMS™ monitoring system interface is fitted as standard on MILO. RMS allows engineers to monitor and troubleshoot all key operating parameters on each MILO – as well as any other RMS-equipped Meyer Sound cabinets – from a remote Windows-based computer.

MILO systems may be deployed in either flown or ground-stacked configurations.


Captive QuickFly® rigging hardware uses rigid AlignaLinks for coupling the units, and allows nine splay angles between 0° and 5°. The rigid connections make for easy adjustment of array tilt, and often eliminate the need for a pullback strap in flown configurations. An optional MG-3D/M multipurpose grid accommodates a variety of flown or stacked configurations, including multipoint support and bridles. A single flown array can include up to 24 MILO loudspeakers, or the equivalent weight of MILOs, M3Ds, M3D-Subs, M2Ds, CQ-2s and rigging hardware. Stacking no more than six cabinets is advised.

With its unique combination of high power and compact size, MILO can serve as the key component in scalable, building block systems comprising any or all M Series products and certain other Meyer Sound models. MILO can be combined with the M3D for very large venue applications, or transition to M2D or CQ-2 loudspeakers for near field coverage where appropriate.

A weather-protected version with a folding rain hood that safeguards the electronics is optionally available.
