A problem that took mathematicians decades to solve, based on original bending wave equations developed by Sophie Germain and Lord Rayleigh, DML is founded on this math, which was famously quoted by Lord Rayleigh in, The Theory of Sound, to be “of considerable difficulty.”

NXT continued this research with a team of over 40 mathematicians and physicists focused on developing a bending wave device for sound reproduction.

The Essence of a DML

Through careful selection of plate material, geometry, boundary conditions and excitation point(s), it is possible to evenly distribute the bending wave modes across the desired frequency range. This ensures a smooth frequency response spanning over seven octaves producing extremely wide and predominantly diffuse sound coverage.



Room Dimension Adaptation

Due to the largely diffuse nature of the sound radiation from a DML, they are more tolerant to room dimensions and construction. This results in a sympathetic acoustic interaction with the space.

Fewer Speakers Required

DMLs deliver extremely wide directivity across the whole frequency range from a single panel. This benefit, combined with the diffuse nature of the sound radiated from a DML, fills the entire room evenly.

Design Flexibility

The mounting methodology for Distributed Mode Loudspeakers is simple due to the flat panel design allowing flexibility in placement and mounting. There is also a considerable weight savings associated with DMLs due to the slim form factor, which makes transporting and installing them a piece of cake.


Remarkable Intelligibility

Whether projecting beautiful music or imparting words of wisdom, the DML was designed for your audience to hear every spoken word and subtle detail in the music. Resulting from the wide directivity and largely diffuse nature of the radiated sound, this is in contrast to a conventional loudspeaker, which generates complex interference patterns and strong reflections within the room.

Simplicity is Key

The entire vocal range is being produced by a single loudspeaker drive unit. This means no crossover in the vocal range or in the critical hearing range. (1-3kHz)
