It is through this multiplication process that the initial acoustic sound generated by the exciter is acoustically amplified. The sound-board in turn excites the adjacent air molecules, causing sound vibrations to enter the room in an almost non-directional manner. Hence, a DML panel is perceived to always be facing the listener, regardless of location.Established well over a decade ago, Amina® is now the world’s leading supplier of totally invisible loudspeaker solutions.
