You are - of course - right
. Especially considering we aren't talking about four digit priced hifi components, but a near field monitoring application - i.e. direct sound will definitely reach the listener before any secondary reflections and those won't even be very strong. But angle of radiation and general frequency patterns of the speaker will have different effects in different rooms. That aside - only a few ppl will completely reconfigure their rooms to accomodate for some ~150€ speakers - so in my opinion it's more efficient to pick the speakers that sound the best in the given room.
