Does Stereophile specify what the deviation from 'flat' can be at 20hz and still qualify for 'Class A'? Perhaps your 802's fall within their range. Normally one thinks of +/- 3db when talking about a frequency response range, but for example down 6db (or even more, depending on your room size)20hz is still excellent output. FWIW.
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?
