Apparent Source Widths (ASW) of phantom images in a ITU BS.775-1 standard surround loudspeaker configuration have been investigated for different signals by means of a randomized blind test. Test signals were generated from anechoic recordings by amplitude panning between adjacent channels. The listening test showed that an increase of Apparent Source Width coincides with the increase of localization uncertainty at the side and back areas of the ITU setup. Largest ASW values were found between RS and LS channels.
