When listening to two channel stereo audio reproduction sounds from the right channel loudspeaker are heard by both the listener's right ear and left ear. Sounds from the left channel loudspeaker are similarly heard by both the listener's left and right ear. This fact has been labelled interaural crosstalk. Here's a brief discussion of it from the Steve Hoffman forum.
Interaural crosstalk can be enhanced or diminished via electronic means and even by the physical design of the loudspeaker. Can it also be accomplished via loudspeaker placement and acoustic treatments? Toe-in could be a tool, but I'm thinking of a setup I saw back towards the end of the last century. I remember visiting a retailer who had a large acoustic panel, maybe 6 ft by 6 ft, that was supposed to be placed between the loudspeaker, but perpendicular to the plane of the loudspeakers. The idea was that the panel would lessen the crosstalk at the listener position. I never heard a demo of the product so I have no idea if or how well it worked.
Does anybody have experience with setting up their listening space in this manner? If so, what did you think? BTW, I've look at near countless virtual system pics and I've never seen this layout. That should tell me something, but maybe not.
