Devialet Ensemble System

[Jean-Marie]

If you go to devialet.com/speakers and clic on a SAMed speaker you can see the lowest frequency before and after SAMing.

It would be nice if Devialet qualified these figures by stating the spl at which the quoted figures are measured, i.e. -3dBA or -6dBA or whatever. Looking at the figures, it looks as if -6dBA or possibly even lower is used, so a bit like the quoting power outputs a 6ohm when the rest of the world uses 8.

I know that the Atohm GT1s were measured at -3dBA. Below is the reference from the Devialet website. No idea about the other speakers that have received the SAM treatment.

Unique design by Devialet
Power handling : 100 Weff
Peak power : 200 W
Impedance : 6 ohms
Sensitivity level : 89dB/2.83V/1M
Frequency response with SAM : 25 Hz (- 3dB)
Cut-off frequency : 2,5 kHz
Atohm ZEF mini speaker cables

Although I have no other evidence than the principle of the Occam Razor I would then be enclined to think that this is the same -3dB for all speakers. I don't see a reason why they would change their protocols with the speakers, nor why they would use a more stringent norm for the Atohm speakers that they sell and less stringent for the other speakers.
