Bose Professional AMM multipurpose loudspeakers feature a passive, coaxial two-way design and purpose-built versatility. Deploy them as mains, monitors, fills, or delays in portable setups or permanent installations. Consistent voicing with Bose AM array modules and Bose AMU utility loudspeakers means you can easily mix and match models from all three lines to create different types of systems. The AMM line is comprised of two full-range loudspeakers and a companion subwoofer, which require Bose DSP to ensure the best possible performance and loudspeaker protection. With a proprietary Bose Beamwidth Matching Waveguide, AMM loudspeakers ensure signature Bose sound quality, delivering consistent frequency response, clarity, and projection across the coverage area — a remarkably powerful audio experience for both performers and audiences.
