Yeah, the differences in measuring outdoors in freespace and indoors is substantial. Eighth-space (corner loading) is 9dB higher than freespace. Makes sense that there is nearly a 10-fold increase because the corner forms a horn all by itself. Even if a speaker isn't corner loaded, you can pretty much expect 6dB just using them anywhere in a room that isn't huge or highly absorbent. Quarter-space (wall/floor placement) is 6dB over freespace, and even if you pull away from the wall, you're still in a confined area.
