Hello Harron,

I happened to come across your posting regarding the NXT driver. I haven't seen the original Industry Update comment (if you could post the gist of it it would be great) but suspect it concerns NXT and their BMR (Balanced Mode Radiator) technology. NXT, as you may possibly be aware, are a UK based organisation that have been developing flat panel transducers that while having some excellent characteristics and wide ranging applications are severely restriced in low end frequency capabilities. Hi-fi they are not. However the BMR technology may just address that. I had never heard of Manger transducers before but in the overviews I have read BMR seems to have a lot in common with this much earlier developed Manger technology giving a wide frequency range, relatively flat profile, non-point source etc. In fact the only difference that I have noticed to date is that while BMR expected to be simple and cheap to manufacture I get the impression that Manger transducers are hand-made and as such expensive.

I would be very intersested in your feedback on commonality / differences between the technologies. As it is new BMR has yet to be released commercially but you may wish to look at the NXT site www.nxtsound.com and a review of a prototype speaker at http://202.186.86.35/audio/story.asp?file=/2005/12/8/audiofile/08golddec&sec=audiofile

With respect to NXT driver: I think it is not a new thing or maybe I am wrong if I am considering already successful Manger driver.

The Manger driver operates in bending-wave mode, so is, I believe, very different from the original NXT drive-unit, which appears to "shake" in a mathematically chaotic manner. The new NXT driver is somewhat different from the original but is, I thought, still not a true bending-wave unit.

(Sorry about the tardy response.)
