Stereophile Class A and Frequency Response


According to the Recommended Components Loudspeaker section in Stereophile, "to be eligible for inclusion in Class A, the system must be full range- ie feature bass extension to 20Hz."

I then noticed that the B&W 802D which is in Class A has a frequency response of 34Hz–28kHz (as mentioned in Stereophile's report on the speaker), which is nowhere near 20Hz.

Why is this speaker included in Class A?

Eldartford- I agree 30hz is good enough for most music, I listen to J.S Bach's wonderful Organ music so like to feel the additional true sub-bass.
