One speaker stereo 2021 04 19

   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. But diagram on the left with voltage drive is the most promising. It provides best beam steering on paper. But other connection ways are also 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
