Which I don't. I listen near field. Still though, the second part of your statement is exactly why I wouldn't want to do this. You don't want location information from the right speaker/channel arriving at the left year, or at least not much of it. Impossible to eliminate all of it nor would you want to.
You do get a very wide 'sweet spot', but the spot isn't very sweet. It's a mess with regards to image specificity. I have four rooms all different sizes and shapes, all with different brands of speakers and associated equipment. Made a mess in all of them, well, the three of the four that I tired. Not going to try the ESLs for the reason I mentioned above.
Might work somewhere with something, but I can't imagine why it would. Sure, it's worth trying as I just did. Didn't work or come close to working for me.
Anyway, much written on the subject, and I'd be happy to argue endlessly (aren't all arguments on AVS) with you, but for now, it's a nice Saturday morning and unseasonably warm so Cars and Coffee beckons.
