What is DML?

​

• DML is a revolutionary loudspeaker technology that embraces diaphragm resonance instead of suppressing it, contrary to traditional loudspeaker design principles.

• It is based on Distributed Mode Loudspeaker (DML) technology, where the panel vibrates in a complex, pseudo-random manner over its surface.

​

Problems with Conventional Loudspeakers:

​

• Rely on pistonic motion, meaning the diaphragm moves as a rigid unit.

​

This leads to:

​

• Narrow sound dispersion (beaming) at high frequencies.

• Frequency-dependent directionality.

• Need for multiple drivers and crossover networks, introducing distortions and phase issues.

• Uneven room interaction and listener experience.

​

How DML Works:​

​

• Abandons pistonic motion for distributed bending waves across a flat panel.

• Generates sound using multiple, overlapping resonant modes, creating a random like motion.

​

Results in:

​

• Omnidirectional radiation, even from large panels. 

• Consistent sound across different listener positions.

​

Benefits of DML:​

​

• Wide frequency bandwidth (greater than eight octaves) with a single panel.

• Scaleable design – panel size doesn’t limit high-frequency performance.

• Consistent stereo imaging, even off-axis.

• No need for crossovers or enclosures, reducing distortion and coloration.

• Improved room interaction – more even sound distribution and less critical placement.

• Thin and low-profile design – panels can be wall-mounted or integrated into displays.

• Dual-sided output – useful for high-end and open-space application
