Devialet Sam for TAD CR1

SAM processes in real-time the musical signal, ensuring that the sound pressure reproduced by the speaker matches exactly the one recorded by the microphone.

This audiophile's dream is working through the very powerful DSP implemented in each Devialet.

Phase alignement over the full spectrum

Extension of the low frenquency response (down to 25Hz)

Effective protection of the loudspeaker, helping to prevent any damage due to listening at high levels

SAM doesn't require any hardware modification, neither on your Devialet nor on your speakers.

Simply activate SAM on the online configurator, your Devialet will automatically recognize your speaker's profile and will be ready to send the perfect matched signal in a few seconds.

So it adjusts the frequency response and aligns phase. How can this company possibly do this better than the loudspeaker designers? Freq extension is physically not possible. This all done via a real time DSP which brings along its own issues.

Freq response adjustment via DSP is a great tool but only when flattening out a response due to room boundary influences, this is not what is being done here.

My feeling is also that the Devialet SAM thing sounds gimmicky.
If it is not a gimmick, Devialet should maybe publish an article on it a well respected scientific journal.

It has been done in studio monitors for years. You can flatten the freq response and phase in DSP very easily (it is much easier than working on room response). Thay also probably add a steep subsonic filter, to limit the bass driver's excursion (and distortion).
