I noticed with both my old Mission 752Fs, and now my jizzmatic Dynaudios,
that the position for optimum treble for each ear is _extremely_ narrow;
something like +/- 1cm laterally.

Anyone else noticed this ultra-narrow-sweet-spot for high treble with
normal tweeters?

No.

Does your listening room have many undamped surfaces?
It sounds like standing waves rather than a very directional tweeter.
