A test concept  of one speaker stereo is done.  It is loudspeaker with 3 fullrange drivers configured in stereo mode. Many ways of connecting it are possible. All of them are investigated. All of themare interesting from psychoacoustic perspective and how they sound.

   The speaker is good for casual in room listening at home. It has no requirements for special placing in room. It does gain from room reflections. And the imaging is very pleasant. Concept is very interesting. It is not new by any means. I suggest reading about it http://elias.altervista.org/html/SingleSpeakerStereo.html
