Definitive Technology AW5500 Owner's Manual page 4

AW speakers may be oriented either horizontally or vertically. Always position
the speakers so that the side with the mid/bass driver and tweeter (the Definitive
Technology logo badge is on this side) faces the listening area. The side with the
Low Bass Radiator may point toward an adjacent surface such as a wall, the
underside of an eave or the ground, as long as there are a couple of inches between
the Low Bass Radiator and the surface. Positioning the Low Bass Radiator near a
large surface will give you louder bass. If you want less bass, move the speaker
farther away from the wall or ground.

Mounting the speakers horizontally under your roof eaves is a good
location (especially if it is on the same level as the listening area). Point the
driver/tweeter/logo side down towards the listening area.
