The short answer is yes. Just design your listening room without any parallel surfaces and have the dimensions increase from the front wall back, much in the shape of a horn. This way, room modes and standing waves are eliminated.
Most all concert halls, movie theaters and ampi-theaters have width and height dimensions increasing as it fans out from the sound source. It's done so that every seat hears the sound at the same volume. Also, every stepped wall, ceiling and decoration has a purpose: to reflect sound to the seats.
If Carnegie Hall was a typical audiophile's rectangular living room, it would not be anywhere near as acoustically efficient. And then it would probably need those silly room treatments.
