Default FR speakers in ceiling corners?

after hearing recently about

"constant directivity cornerhorn design"

William Cowan's Homepage

im wondering if the principle can be taken a little further by building

a speaker box (sealed) that fits into the corner of the walls AND the ceiling, and aims the FR driver toward the center-ish of the room, using the whole corner (3 sides) as a wave guide.


or is half way up the wall (equal distance from floor and ceiling) and ignoring the ceiling surface a better way to do this?

ill be installing these speakers for a friend in the next 2 weeks,

im trying to fill a whole room with beautiful Full Range sound,

not just have 1 small sweet spot.



i did get this response from someone, but im not sure if they believe the ceiling corner is a better or worse option

"if you put the sound source right in the apex of the corner (within 1/4 wavelength) then there will be no self-intereference notches from the boundaries. But when the source is placed some distance away, self-interference notches form. This is why many people move their speakers as far away from walls as possible. But this is only one solution, the second one (which I believe is better) is to place them flush with the boundaries. This has additional benefits."
