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?

Gawdbless,,,It's that last octave, down to maybe 16 Hz, which lets you FEEL some organ music. If you don't play that kind of music 30 Hz is plenty good.

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.

Kinda like the Car companys all claim at least 3 miles per gallon better than they actually get on an average useage.. Never believe everything unless proved in truly optimal environments and that means the ones we actually use not some perfect built isolation booth.
