At last here is the reply from Dali:
Dear Tony,
Thank you for your e-mail.
The LEKTOR 2s are designed for wall mounting.
	The performance from the speakers will vary from room to room depending on the
	acoustical properties of the room. I do not know under which conditions
	WHAT HI-FI tested the speakers under, so it is very difficult for
	me to comment on their judgement of the speakers.
It will also be possible to stand mount the
	LEKTOR 2s, but expect, that the bass output will be slightly reduced in
	comparison with on-wall positioning. My recommendation is, that you audition the
	speaker in the nearest authorized DALI dealer. There you will most likely also
	have the opportunity to hear the speakers on-wall and on a stand (or
	longer from the wall).
Med venlig
	hilsen / Best regards,

Well no surprises there!! Best to audition but it does sound like they should be ok against a wall.
