CHOOSING A MOUNTING LOCATION
CDD Series loudspeakers should be mounted above head height – high enough to clear peoples'
heads for clean coverage but low enough to avoid over-exciting room resonances.
Tilt angles should be set so that the loudspeaker's maximum output (usually on-axis of the
loudspeaker centre) is aimed at the furthest listener across the room.
The horizontal dispersion pattern of CDD Series speakers tends towards a square due to the
design of the coaxial driver. For this reason, mounting speakers in the corner of rooms should
be avoided.
NOTE: Care should be taken when co-locating CDD Series speakers, either adjacently or in an
array. Due to the Differential Dispersion characteristics if two (for example) CDD speakers are
placed adjacent to each other, there may be an overlap in horizontal coverage in part of the
intended area, which could lead to unwanted comb filtering.
