Mechanical separation of speakers is not for everybody but it works for me too....
Interaural Crosstalk And Loudspeaker Setup
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.

Here the 3 main negative effects as described by Dr. Choueiri numerous articles : « Effects of Crosstalk

In Nature we hear one sound source for the melody of a bird for example. In a living room with speakers we hear 2 sound sources for the same melody which impede the naturalness and information of spatial dimensions of the perceived sounds. 2 speakers stereo are unnatural situation .
In a word for our brain deciphering our 2 ears channels there is 4 speakers in the room:2 actual and 2 virtual because of the time interaural differential function. Choueiri explain it all and his mastery of the subject is complete. Read him. |
My room is under my acoustic mechanical control... My speakers heavily mechanically modified too... I also use a mechanical separation between the 2 speakers for my near listening situation...(unpractical for most people.)
