Actually it’s what we call misinformed. And that’s being nice. The "wall of sound" was a technique of Phil Spector who liked to create a sound stage wide and flat and in your face. As such it is a recording technique not a speaker characteristic. Speakers cannot create a wall of sound, they can only recreate the wall of sound if present on the recording. Bose used 9 drivers in a configuration designed to create wide diffuse sound, the opposite of a wall of sound. The drivers are midrange not tweeters. Eight of them fire at the wall, not towards the listener. As such the Bose 901 is totally incapable of creating a wall of sound, even if one is there on the recording.
So as you can see this is not at all damning with faint praise.
I think that pretty well does it for tearing that one apart.
