Martin Audio AQ Series - Manual (Page 15)

The complete installation should be checked and approved by a qualified structural
engineer and a qualified electrical safety consultant before being signed off.
7. Vertical aiming
AQ 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.
