DISTRIBUTED MODE LOUDSPEAKERS
Distributed Mode Loudspeakers (DMLs) utilize bending wave modal physics to propagate very wide directivity, predominantly diffuse acoustic energy into a given space. Unlike traditional loudspeaker systems, the net effect is a single, large drive unit that radiates audio over almost eight octaves in a very wide and diffuse manner.
You can currently find them in airports, gymnasiums, ballrooms, luxury hotels, houses of worship and professional music studios. They’re even in the government chambers at the South Carolina House of Representatives. Really, the sky’s the limit.
