I am not sure where the low listening levels come from because we have also sold them to recording and mastering studios.
The proof is in the listening of course , five minutes is all it takes .

The issue with high low end distortion at medium and high listening levels can be seen in the review here.
You yourself posted a review here which referenced this and moreover said:
The trade-off for such a compact design is always going to be increased distortion / restricted SPL - the graphs in the review linked just above show that over about 90dBSPL things start to get hairy down low. Some people have flagged this as an absolute show-stopper, and they're right in as far as it's a potentially serious failing.
The reviewer was content to live with this limitation; many would not be. Claiming response down to 19Hz +/- 0.5dB at any decent listening level is just utter nonsense.
