The newly expanded AMU multi-use loudspeaker series combines a powerful mix of driver configurations and coverage patterns with a variety of mounting options and orientations. Together with indoor/outdoor flexibility and two colors, AMU offers virtually endless installation options to solve your specific needs.
Featuring high-output sound, exceptional vocal clarity, and rich musical depth, the AMU Series shines in both large distributed and small- to mid-sized audio systems. The integrated 70/100V transformer includes a bypass switch for live sound reinforcement. Systems can be enhanced with the MB210-WR dual 10-inch weatherized subwoofer, and PowerShareX amplifiers include factory-optimized presets for peak performance and simplified installation.
