8.1.1 ACCEPTABLE MOUNTING POINT LOADING
The mounting points should be always be used so that either shear force is applied perpendicular to the
direction of and in tight proximity to the mounting hole or tension force is applied perpendicular to the enclosure
surface.
DANGER: Use the mounting points only as described above and shown in FIGURE 2. Do not use them in
such as way as to apply sideways leverage to them. Failure to follow this instruction could result in
immediate failure of the mounting points resulting in damage to the loudspeaker and serious injury or death
to personnel.
8.1.2 MOUNTING OPTIONS OTHER THAN THE R1YOKE
Eyebolts: A forged, load-rated, shoulder eyebolt may be used to suspend an R1. The eyebolt must be screwed
in so that the shoulder firmly contacts the surface of the enclosure. In all cases the direction of pull on the
eyebolt and mounting point should be in tension not to exceed a maximum of 30º from the vertical axis of the
mounting point hole (See FIGURE 2). While a single mounting point so used can support the weight of the
loudspeaker with a greater than 5:1 design factor, a safety cable that can independently support the
loudspeaker must also be used. Other mounting points can be used as pull-back points to fix the aiming angle.
Custom Mounting Brackets: Custom brackets may be used. When mounting the loudspeaker the bracket
should pull directly either in tension or shear on the mounting point (See FIGURE 3). It is recommended that
any custom bracket be designed to utilize two mounting points on the opposite sides or top and bottom of the
enclosure.
8.2 ORIENTING AN R1
An R1 has a definite top/bottom and sides. However, a 180 degree inversion will not affect the coverage.
When the top of the enclosure is up, the input cable gland-nut will be down and to your right when looking
directly at the front of the loudspeaker. Also, the manufacturer's label is on the top of the enclosure. Once the
top is determined, you can properly orient the loudspeaker for your particular application according to the
specified coverage pattern.
