Devialet's newest technology...?

[f1eng]

I am curious about the driver technology used in the Phantom but I have not seen anything except the the slogan "heart bass implosion". I can see Devialet's expertise in amplification and DSP allowing them to design an excellent active speaker but the claim of zero distortion is difficult for me to understand. I have not seen any woofers (or sub) with distortion levels below 1% at frequencies under 80Hz or so. Feed back or more like with Devialet feed forward speaker correction can correct electric driver behavior and therefore reduce distortion but mechano acoustic behavior of drivers and box can not be eliminated just through DSP.

The mechano-acoustics errors of the entire driver/enclosure are part of what is measured in producing a SAM correction so is indeed included in SAM.
As long as there is enough DSP to run the inverted transfer function of the speaker error in real time all of the faults in the speaker behaviour measured by the SAM procedure will be compensated for (not eliminated). Since the measurements include the audio output, all the errors are compensated for.
