nxt vibrating panel

NXT - Simeon Canada

Doesn't all this resonance in the panel colour the sound unacceptably? The surprising answer is no, it doesn't, because of the highly complex nature of the panel's vibration. An NXT panel's impulse response figure 4 displays a long resonant 'tail' which would damn any conventional loudspeaker, but its sound is clear and...

21st-NXT/Azima - Vxm.com

An NXT panel closely approximates a randomly vibrating diaphragm, and so behaves similarly. Distributed Mode operation is therefore ideal for a loudspeaker: it guarantees consistent output level and undistorted time response in all directions. In other words, all the radiated energy appears to originate from a single point.
