"Filling the room with emotion" What does that even mean? Note that how the recording was produced helps define the intended soundstage and no recording, mixing, or mastering studio uses dipoles, so you're not getting the intended soundstage. This goes back to the personal decision of wanting accurate reproduction or to be entertained.
True, I should use less poetry in my posts

,
I meant having an enveloping soundstage, I simulate that by having my current speaker quiet close to the wall and orient them not directly at my hears but
1 meter from my shoulders. I can hear a central image and left right cues in tha sound. With the Martin Logan, it's coming from all directions.
The type of sound I like is the sound you hear in events and regardless of the studio recording technics.
I am not sure, but I don't think sound engineers think about dipole either, they certainly focus more at apple earpods and car audio system where 99% ofthe people will listen to music. If it was to reproduce a studio type of sound, then I'll buy studio monitors same brand and model than in studios, but I don't think I have the same goal in term of accuracy and sound analysis to tweak a recording, versus a listening experience that conveys a life and feeling of beeing at the event. Basically when I listen to speakers and it makes me more checking boxes than nodding my head, I am not really convinvced.
"Boomy sub..." What sub is this? Do you own this sub? What "very well treated room" are you talking about? If the room is "very well treated" how is it vibrating? This is a common compliant of cheap subs - one note, lacks definition. Have you tried repositioning, adjusting phase/volume?
It was the SUB in the 15k Martin Logan, so I don't own it ... yet

, and the setup was done by the staff of the retailer, and when the sound was put at a high volume, the panels started to vibrate. And no we didn't try to adjust the Phase and volume, but I'll ask the guy to do it in my next audition. I,ll ask for a smaller model as well, I think the room was too small for that pair of speakers overall, so I'll keep you posted, I think the adjustment and fine tuning should be a good way to refine the sound.
"Voice projection equally from speaker and (front) wall..." Welcome to dipoles/open baffles. What else would you expect? There is no perfect speaker, so pick your medicine.
Expeccting a miraculous silver bullet speaker solving all the earth problems

, you are right, I'd choose clarity speed and openess then

"...very fragile..." Yep. Had a 6 pound cat tip over a large monitor on a 12 inch tall stand (broke the binding post).
Oh my ....., I can only imagine your reaction in slow motion watching the scene !!!. BTW I have the cat and the 50 pounds little boy .... So ... RED FLAG for me !
