^^ here's a video showing how time intensity trading works.
Way back in the 1970's or early 1980's, Leslie (the organ speaker people) came out with a home speaker system that had a narrow dispersion, but uniform frequency response on and off axis, and the drivers positioned so that the response axis crossed well in front of the listener even when the boxes were pointed straight forward. The Leslie speaker is doing exactly what is shown in the video for trading volume intensity and the timing of arrival. I thought the trick sort of worked, but, the speaker did not sound that great.
I've tried the extreme crossing angle myself, and I did not really like what it did to other aspects of imaging, such as the sense of depth and the sense of sound enveloping the listener. Still, it is a "free" upgrade if it works, and a reversible one if it does not.
Yes, indeed, though the Ohm Walsh crowd seems to be OK with this. Maybe because some were only omni’s up to a point?

Regarding room interactions, you look at the Relative Power #s at the various frequencies on/off axis in the diagram at the bottom of the page linked to above, you will see the Ohm Walsh’s are specifically designed to address that, unlike full omni speakers.
You will find they can go closer to walls than many others for that reason, and definitely closer than full omnis like GP or mbl. Very easy to set up and get very good results though fine tuning as always will still yield improvements.
a point source (Tannoy, Shindo, Duevel, Fostex) creates much better integration of direct and indirect sound as well as a larger sweet spot
The other speakers I own and enjoy besides my two pair of Ohm Walsh are KEF ls50 (originals and metas). The Metas in particular have very good off axis dispersion and a decent sweet zone, especially for a more "conventional", though technically advanced, box design.
