Stereophile Class A and Frequency Response

The definition of "bass extension" is a bit subjective, and said to be responsive to advertising revenue.

B&W has always been a favorite of Stereophile and they do make great speakers. However, to include a speaker with limited bass in that category is misleading, at best. By their own measurements, the 802D is -10 dB at 20 Hz!

Soundstage/Ultra Audio measured 0 dB at 20 Hz.

Who to believe? Also, there is a hump at 60-70 Hz which gives the feeling of fullness in the bass and may compensate for the roll-off above Stereophile's measurements. I would argue that -10 dB is significant at any frequency. Companies should tell the customer whether the measurements are anechoic or in room, +/- 1 dB and +/- 3 dB, and if that is flat across all frequencies. It doesn't tell you if the speakers sound good, but is a basis of comparison between speakers. Personally I find deep bass indispensable to all music I listen to and for my money, if a speaker is down 10 dB at 20 Hz, it needs a subwoofer. Just my opinion. (Lets the flames begin!)

Whats half an octave (or less) between friends?

I guess the late great John Dunlavy wasn't a friend?

Ah America, the land of stats, stats and more stats.
