Yeah. Theory is a lot more strict than reality.

Once, at band camp... sorry, wrong thread. Once, a system was designed to use the motorized Kef loudspeakers. The house was a well-built 1930s model; this was the first floor of two. When we opened the ceiling, we found the structural wood was much too crowded for anything but run of the mill Sonance inwalls, so we apologetically put them up.

Despite the fact that the speakers were at about sixty degrees to the listening area, they sounded GREAT. It's really hard to just "try out" something like that, but if there's any way you can, you'll probably be relieved to hear taht they sound just fine.
