Zusammenfassung:	A videoconferencing system (100) has a plurality of displays (140-LCR) arranged side-by-side. Top loudspeakers (162-A) are arranged adjacent the tops of the displays (140-LCR), and bottom loudspeakers (162-B) are arranged adjacent the bottoms of the displays (140-LCR). A control unit (110) operatively coupled to the displays (140-LCR) and the loudspeakers (162-AB) routes video to each of the displays (140-LCR) and routes audio corresponding to each display (140-LCR) to any of the top and bottom loudspeakers (162-AB) arranged adjacent the display (140-LCR). Thus, the top and bottom loudspeakers (162-AB) form a vertical pair (160-LCR) of loudspeakers that output the corresponding audio for its respective display (140-LCR). In this way, the audio for the video of a given display (140-LCR) is perceived by participants to originate from the center of the given display (140-LCR). If one of the loudspeakers (162-AB) is not provided, gain setting and mixing between adjacent sets of loudspeakers can produce a virtual loudspeaker for the one that is missing.
