What‘s DML Technology?

A DML - Distributed Mode Loudspeaker - is a panel-type speaker which produces sound via vibrational modes, propagating across the whole panel surface. DML speakers are actuated by very sophisticated audio exciters – a type of transducers specifically designed to excite the entire panel surface.


It uses micro-vibrations to generate digital sound, allowing the ultra-thin construction of visible Hidden Sound speakers with unprecedented elegance and lightness. Or even the installation of invisible, completely over-paintable versions of the DML speakers into any drywall or dry ceiling construction.



In 1991 UK’s DERA (Defence Evaluation & Research Agency) discovers DML technology for military usage of sound, but only later UK hi-fi companies try to develop it for commercial usage, and fail to launch a successful consumer product.


DML arguably marks the biggest revolution in the 100 years history of loudspeakers.

DML speakers are actuated by sophisticated audio exciters – a type of transducer specifically designed to excite the panel surface.


It uses micro vibrations to generate digital sound, allowing the ultra-thin design of visible, and even invisible, HIDDEN SOUND loudspeakers to be produced with unprecedented lightness, or even built into any dry-wall or -ceiling construction, and be painted over.


The secret of turning DML speakers into an audiophile HiFi system, lays in our unique, signatory DSP (Digital Signal Processing) engineering – the brain of the system – which is built into the HIDDEN CUBE, driving the whole sound system with its speakers.
