I love me some Linkwitz. I've poured over his pages of data and learned a great deal. His scientific method appears solid, however nobody is immune to the subtle effects of bias,...and I found these quotes wrt center vs. phantom;"This is not a system for home theater""At this point I am not convinced that a center speaker in my system is worth it, even if it is placed out of sight most of the time. Sitting in front of such speaker is visually highly distractive and its benefit for multi-channel sound is marginal, given the satisfying sound stage that is set up by the ORION.""The center speaker adds additional signals at the ears that are not necessarily time coherent with the other two speakers' signals, because of the overlap in the three microphone pickups. This may have caused the effect that was observed."
These aspects are fundamentally oriented toward systems that are primarily geared toward music,...whereby the acoustic information from the recorded event is spread across the three mic elements. Additionally, although it states last revised as of this month, much of the information on that page appeared somewhat dated. With multichannel material that's associated with contemporary techniques in film and TV mixing today, the hard panning and dedicated center channel material and dialog, translates solidly to a multi-person group of listeners in typical residential rooms. Regardless where someone experiences the recorded event from in the room, the dialog is entirely correlated (no phase issues) and solidly placed as centered with the visual element.
In my non-dedicated listening/HT room, listeners are splayed all across the room, and spaced at different distances front to back. Aside from the detrimental HRTF transfer function I stated above (two octave wide 2khz dip), a dedicated center locks the hard panned CC material to the image, and retains clarity and intelligibility to a high degree.
Just my 2 cents

The Danley Synergy Horn
designs may be of some interest. They work in concert with the subsequent wall corner angle that results from corner placement, and I've seen them recommended by Danley to individuals in this scenario in which you find yourself. So, food for thought. Clearly, their designs are very low distortion, high output oriented, and controlled directivity approach,...directing the acoustic energy off the sidewalls, and toward the LP,... allows for further clarity and less detrimental effects of less than ideal acoustics.
Hope this helps. Even if you didn't pursue the Danley mains, perhaps this opens things up a bit and facilitates you finding some avenue that gets you there. The Danley products are availed to consumers in custom skins as well as the typical pro style, AFAIK.
