Meyer Sound MILO Powered Line Array Loudspeaker

Meyer Sound MILO Powered Line Array Loudspeaker

MILO is a self-powered, four-way loudspeaker designed for vertical curvilinear arraying. It has ample power reserves (140dB 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.

Features:

• Extremely high power-to-size ratio for lower costs and flexible installation
• Exceptional fidelity and peak capability assure clean, high-impact response
• Seamless integration with other M Series models
• QuickFly rigging system simplifies use in flown or ground-stacked arrays
