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.
Care to share a typical dipole ETC?

I meant "blurry", no clarity. Low level details get lost. Which is exactly what a concert hall does but do you really want to hear each and every recording "concert hall style"?

Which omni and dipole designs have you auditioned, properly setup, at the right listening distance in a suitable room to justify your statements ?

Orion What is a suitable room and what setup is best? When I read through the posts of most omni/dipole proponents here, completely opposite setup recommendations can be found.

I felt inclined to play around with a simple low SPL (mean 75 dB) nude dipole. I attached the nice 3" Vifa full range to 10" woofers and cross electronically around 500 Hz. I wanted to see how they differ from omni.

One thing that bothers me about these types of speakers (omni, dipole) and their need to be away from walls, is that they force you into the near field where the problems with stereo are accentuated. Small physical movements become large w.r.t. the stereo triangle.

I really think it's better to get the speaker as far away as possible, if one wants to give stereo a chance.

Talking about MBL - is this the best way to place an omni?

I'm not so sure the traditional stereo triangle is an optimal layout for dipoles. I prefer a setup that puts the speaker(s) an equal distance to the listener (slightly off axis to the listener) ... and almost twice that between the L/R channels. So, a triangle with a much wider base. The sound stage seems to be broader.

Not true at all.

Well, its surely better than a 1" dome...no?
It would also be open backed, so no need for 2.
I'm sure a 2" could be crossed at 3kHz rather than 7kHz for better vertical polar response?
