Not really... Why does someone like StigErik treat his room the way he did? He doesn't like "realism"?

For Bob Richards: Have you ever heard the "spoken word" recording "I am sitting in a room"?
I Am Sitting in a Room - Wikipedia, the free encyclopedia
We "studied" this in a college class (Electronic Music) and it illustrates the increasing room resonances as each generation of recording is repeated. You don't have to listen to the whole thing

I did that too, back when I had Maggies with the "true ribbon" tweeter . . . they were just too bright otherwise. But there are better ways to address the negative effects of excessive high frequency reflections without losing the benefits of reflection in the mids . . .

A 2" FR lacks the surface area for the needed low end boost in a dipole, unless you have about 20 drivers on a side which will wosen comb filtering paticularly if not being low passed at 6-7 khz.

I "experienced" that effect just last night . . . I was walking on the UCB campus talking on my cell phone (I'm so ashamed ) and passed under a covered walkway (at the Music Building of all places) and the reflection of my voice from the roof made me stop . . . my wife could hear it even over the phone as I walked back and forth from under the "ceiling" . . .

Indeed. That's why I don't think that anything omni is a good idea unless one wants realism "on the cheap".
Why do you consider an Omni so inferior to a dipole ?! An omni like pluto sure sounds more realistic than simple boxed monopoles . And as per comparison between pluto and orion by SL himself, these two speakers sound quite similar. Actually pluto can sound like orion at a closer listening distance making omni preferrable to dipole in a small room.

Adjustable rear tweeter? But what's so desirable about very early, very loud front wall reflections?

I don't. I consider both inferior They do sound more realistic than high(er) directivity speakers but they also sound like this:

Where do you get "very early, very loud" ? ? ?

If the single "between the speakers" specular reflection is diffused or absorbed then the reflections are twice reflected, multidirectional and delayed by at least 15-20 milliseconds . . . and individual reflections are generally 10-12 dB down, often more. The resulting diffuse sound field is much more satisfying than multi-channel synthetic reverb from a couple more point source speakers.
