Andy, the usual problem, as Merlin refers to, is maintaining wide dispersion at higher frequencies. If JBL have solved this, that's indeed a breakthrough advance.
For the current ATC models the 30 degrees horizontal off-axis response is pretty similar to the on-axis response, certainly in respect of the mid/tweeter crossover region. So I am less inclined than Merlin to blame dispersion of the mid unit. There may be a trade-off elsewhere that isn't obvious? I can't be sure - but hence my hope for some improvement from the new tweeter.
As a general comment, it's only worth making serious comparisons when measurements have been taken by the same (independent) people with the same procedure and equipment.
