If you get the ATCs make sure you have more than enough distance to allow the drivers to blend.
when I heard them the dome midranges were noticeably incoherent with the other drivers (they have a very limited bandwidth compared to a conventional midrange). This resulted in frequent image shifting in vocals- very unpleasant.
I was listening from about 15 feet away, i would recommend at least 20 feet.
the Spendors on the other hand are incredibly coherent from 9 feet and beyond.
Above highlighted statement makes no sense to me. The 3-way active ATC's I've heard, with their famed ATC SM75-150S midrange dome, have been anything but incoherent sounding - even at closer distances <9ft. And the midrange driver doesn't cover a "limited bandwidth" but rather ~380-3.5kHz, and thus a substantial portion of the lower mids up through the upper mids. Most coned midrange drivers in 3-way setups can't cover this range, mostly because of beaming issues or irregularities in the upper registers. A lower crossover point (i.e.: <380Hz) would sit in the important "power region" - choices, and (different) compromises.
A proposed +20ft. listening distance for them to cohere properly seems preposterous. That would make them a stretch for use in many if not most home environments, not to mention being highly impractical for their intended use in close monitoring recording studios. Maybe it's the highly revealing midrange of theirs that isn't your cup of tea? But incoherent sounding? I'd never call them that.
