I run Proac 3.8's in a 13X24'room with vaulted ceilings. No problems whatsoever! I've also had the D38's in this room and did not like them as much. The D38s needed a little more break in time however they were just fine in the room.
I used to have Proac 1.5's and the smaller ones and although excellent sounding just don't give you the realism of a larger (ie taller) speaker. The height of the tweeter may have something to do with this as the 3.8's are quite a bit above ear level.
