A revolution in sound reproduction or a flash in the pan like NXT?
Anyone heard one?

It looks like an undersized speaker with a high powered amp and bass
boost to give a flat response down to a claimed 16Hz(-2dB) at low
levels, or 49Hz(-2dB) at high power levels.

99dB from 750 watts? They have to be kidding. Anyone can make a speaker
nominally flat by attenuating all the power above the lowest frequency.
These may prove to be more popular in winter than summer.

I'm guessing as I know nothing about the speakers. However I suspect
Devialet will be using a 'digital' sic amp and using some kind of DSP to
'correct' for the speaker's impedance and distortion characteristics. If
so, it may not be as wasteful of power as a traditional type of power amp.
That said, I have no idea how successful the results will be. No doubt it
will intrigue reviewers for its novelty, etc.

Well, 750 watts is producing what 1 watt should do, which means they
are suppressing everything but the lowest bass by about 28dB.
