I have Ohm 1000s (and owned the original Ohm Fs some 45 years ago) and one of the unique aspects of Ohms is their incredibly big sweet spot. Uniike many speakers that only image well when the listener is in one small, very specific spot, I can be pretty much anywhere in the room and the image is realistic in the same fashion as if you were wondering around while listening to live music.
This works both ways -- while still desirable, the speakers don't have to be set up completely symmetrical in order to sound good. However, keep in mind that Ohms have not been completely omnidirectional for many years. There is some attenuation within the speaker cone to the outside rear quadrant of each speaker (the two speakers are not interchangable between left and right), but once that is taken into account, there is great versatility in their setup while still giving good sound.
