NXT Exciters

[Ron E]

Has anyone done anything with these? It seems like they could be useful for noncritical applications or unique art exhibits. How picky are they about diaphragm shape, stiffness, thickness, etc? Are there any frequency response plots of DIY results out there?

There is a really long thread about this subject in the Planars & Exotics forum. Can't remeber the name of the thread though.

EDIT: Here it is....

also as you'll find in that thread they are used in the podium planar loudspeaker which got good 'hi-fi' reviews... an honeycomb stiff leightweight panel seems to take the best out of them in the podiums:

also from nxt studies the balanced mode radiator was developed which is used in the Naim Ovation floorstander

There's also a long thread over at AudioCircle on this here:
NXT.......rubbish??....THINK AGAIN! with lots of experiments with different exciters and panels.

NXT generated a whole lot of AES technical papers.
