Kef Reference 3 + Devialet 200

[dogbait]

People seem to be getting confused between bass volume and bass frequency.
These small speakers will not be able to go very loud at the low frequencies, obviously, and with the thermal and displacement mapping so well explained on the web site if you turn them up a lot the low bass will be progressively reduced relative to the mid range.

I see, so for instance the SAM database gives 28.6Hz for the KEF LS50. However the bass volume (SPL?) would be very low for that versus a much larger speaker which also only goes down to 28.6Hz?

If so what is the point of the SAM figure? Shouldn't it be quoted ideally with a SPL value as well?
