Conventional Loudspeakers generate Sound with the piston movement and the resulting vibration of the membrane. This design also requires a rather large volume of the loudspeaker housing. The limitations and shortcomings of the conventional technology are commonly known. The NXT-Technology of New Transducer Limited represents a new and radically different principle. An exciter unit actuates a flat panel into vibration. As a result a complex pattern of uncorrelated bending waves develops that produces the sound (DML - Distributed mode Loudspeaker).
