What image enhancers do is reduce the inter-aural crosstalk that occurs when the left ear hears the right speaker, and the right ear hears the left speaker. This reduces the width of the image and slightly alters the frequency response of the source. Image enhancers introduce anti phase signals designed to cancel the crosstalk which widens the soundstage to the degree that from a single point between the speakers you can almost hear some sound that seem to eminate from behind you. The best image enhancers are tailor made for the speaker(polk SDA comes to mind) however the Carter Sonic Holography cicuit worked incredibly well on all speakers.
