Normally a speakers specs are quoted as +/- 3db. I think i recall reading somewhere that they may be quoting their numbers at +/- 6db...
I am almost certain that they are using a -10dB figure.
I am not sure of that. For instance with Kef LS 50 : without SAM, Devialet announces 44,8 kHz. Kef site tells 47Hz - 45kHz (-6 dB).
I think they have their own protocol, as their sound pressure graphics : "Measurement realized on Angel by Massive Attack ". Non conventional protocol
