Going all the way back to the OP's original lost, the speaker / room interface is typically corrected in the passive realm via room treatment, correct?
Bill Dudleston at Legacy Audio came up with some crazy speaker designs to combat room coloring, mainly the Focus which used the typical D'Appolito config to create the midfield 'lobing' (sacrifing vertical vs horizontal dispersion) and then more exotics like the Whisper.
I never did like the Focus, nor designs like it. The Whisper was fa more neutral, but used a stupidly complex driver arrangement to cancel out average room interactions. The net result is both speakers were very large, but sounded very small, and were very $$$$.
Room treatment seems a more practical alternative. We also have to realize speaker drivers radiate in all directions unless waveguide / horn loaded, hence wasting power and efficiency and creating unwanted room interactions. Focusing / nulling out this problem with DSP seems to be an increasing trend.
I still think the idea of using multiple driver arrays with each driver having it's own discrete active driver is the way to go, and would yield incredible amounts of control. Or just use headphones.
