Don't you see? It's expensive; therefore, it is good! It doesn't matter how it sounds or how it measures! You just have to look at the price tag. That tells you everything you need to know!
In all seriousness - as to why it could measure the way it did and yet get no mention of it in the subjective listening review:
Like I keep on saying here, what the speaker is putting out is only half of the equation. The room is the other half and when it comes to mid-bass, room interaction can be all over the place!
Combine that with the fact that human hearing and memory is just plain unreliable and the even more important factor of the human brain's ability to ignore a tremendous amount of distortion and extraneous sounds and it's very easy for a SERIOUS flaw to be over-looked. And that's not even mentioning the effect of knowing a speaker's price, liking its looks and thus deciding before ever listening to them that you're going to like them.
It comes up all the time: people see amazingly bad measurements and ask with indignation, "how can that be?! I liked what I heard! The measurements must be wrong!"
Measurements CAN, of course, be wrong sometimes. But if they are accurate and just happen to be "bad", but a person still liked what they heard? Doesn't really mean a thing. It's just more proof that human hearing is anything but the pinnacle of a reliable metric.
