Uhhhhh.....last time I checked, playing the same mono signal through two identical speakers produced a phantom image mid-way between those two speakers. If they do not, the speakers are out of polarity! Just about every stereo recording that contains a vocal has had that vocal reproduced as a phantom image midway between the two speakers. There's a little knob on mixing consoles called a "pan-pot" that allows this technological miracle
