Refer to the section drawing of the speaker and ensure that there is enough clearance behind the plasterboard (sheetrock) for the clamps to swing out fully.
Avoid installing the speakers in the same cavity as flimsy ducting, which may be induced to rattle.
The speakers are designed to operate satisfactorily in a wide range of cavity volumes, ideally above 15 litres (0.5 cu ft), so make sure the volume is not too restricted by cross studs.

Front speakers for audio or home theatre
The CCM 817 is ideal for use when it is required that the speakers be mounted in the ceiling so as to be as unobtrusive as possible. For home theatre, they should be mounted about 0.5m (20 in) from the plane of the screen or the front wall in the case of an

6.1 channel
Position two speakers to the sides in line with the centre of the listening area and one centrally behind the listeners, with the frames rotated so that the drive units are directed towards the centre of the listening area. (figure 5)
