Devialet's newest technology...?

[Music or sound]

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.

As far as I can understand it DSP can correct for some types of distortion but not all.
Let's assume that the signal is 100Hz and its overtone of 200 Hz. Any error in timing and level between these frequencies can be corrected through DSP like SAM if one knows the system. It also could correct for different behaviors at different absolut levels.
If that signal causes also some enclosure vibrations at 300Hz (enclosure and membrane vibratios are chaotic in nature and not necessarily idential to the stimulating frequency)any correction at 300Hz would not be effective as the signal does not contain 300Hz.
