I have 3 BL17s close to the ceiling (highly recommend for size & output quality) although I have them in portrait angled in to the centre of the room rather than landscape and angled down.  I do however use them as height speakers in my Atmos speaker group and they are more than a match for the Theatre Centre Front.  Equally they sound great in Stereo for music.  Only thing to be aware of they are louder from the same input & db level being close to the ceiling, but the calibration equalises all speakers.
