MBL omnidirectional speakers

[Music or sound]

I listened to Muraudio at a show some years ago and liked that there were the first electrostatic speakers with a real wide (360º) sound distribution. The problem I have with especially the larger MBL speakers that the different driver have very obvious different acoustical centers and it is very obvious when one moves ones ears up and down (standing vs sitting sounds quite different). So a problem with vertical but not at all horizontal (2d vs omnidirectional-3d).
The smaller models and German Physics have much less of that problem.
