I go your way. Especially single speaker pink noise audition can pick up resonances that become obscure in stereo.

That is why they image peculiar. Its this room factor they excite a lot. I am sure they were imaging a bit soft but grandiose in Mirage headquarters when designed. such speakers as panels need much room and attention. A pain in the behind really.

Interesting issue

I often find small adjustments in crossover have influence on imaging and soundstage and in particular focus

You cant judge that in mono, I have tried and it always changes when I listen in stereo afterwards - like Svante said, "you measure in mono", and I guess there is no other way

Question is if a perfect stereo pair is different from the one which measure perfect in mono, and when, in which way

BTW, I sure would know how to measure a bipole or dipole like MIRAGE or others of the kind

Listening position only. Anything else is meaningless for the most part.

Well, what I actually think is that a speakers ability to reproduce soundstage, imaging and focus on soloists must be phase related

Actually wouldnt there be a phase problem between left and right
I mean they are so far apart, which in normal terms would lead to phase issues - maybe one have "cheat" on this part

For all measurements mono (outdoors if practical). For initial voicing, mono because it is quicker and easier to spot major issues. For final voicing, always stereo because it is more revealing of subtle performance issues like soundstage and imaging. Partway through the process, I may switch back and forth between mono and stereo, depending on what I'm hearing.

Hi again Salas,

You are right about peculiarity of image due to bipolar radiation.
But I have serious doubt about how they
can sound in the "headquarters".
My friend have a big room and we have spent long time in
positioning the M1 . Are 2 metres from rear wall sufficient?
We have tried also 2,5 metres but .....nada!
I think they image exactly so.
Subjectivaly an Avalon , Thiel, Manger are another world.
Excuse me for the OT.

Cheers,
Inertial
