POSITIONING AND MOUNTING THE LOUDSPEAKER
Place the loudspeaker so that the line of the acoustic axis points towards the
main listening area. The AV install designers may indicate different aiming.
Minimum clearance for amplifier cooling and reflex port function around the
loudspeaker is 3 cm (13/16 in) behind, above and on both sides of the
loudspeaker. If the back side of the loudspeaker is blocked, the back side of the
loudspeaker must be ventilated so that the ambient temperature remains below
35 C (95 F) under any moment of operation.
Figure 2. Definition of the acoustic axis.
The two primary mounting points are on the rear side. Use these for mounting
brackets or the keyhole wall mount adapter. They have metric M6 x 10 mm holes
(thread type is metric M6, thread depth is 10 mm). Do not exceed the thread
depth as this can result in failure of the thread. The base of the loudspeaker
carries a 3/8 in UNC-threaded hole compatible with a certain standard
microphone stands. This can be used for additional support. The UNC thread is
not compatible with metric threads. Do not use this point as the primary mounting
point. Pay attention to mounting screw lengths. Do not use screws exceeding the
depth of the hole as this can destroy the threads in the mounting points. Do not
over-tighten. Do not use very short screws as the thread length covered by such
screw is not enough to hold the weight of the speaker.
