11 PHYSICAL INSTALLATION
11.1 IMPORTANT NOTE: Mounting/rigging Point Holes
The mounting/rigging points of the SLS and SBS loudspeakers must either be used for mounting
hardware or “plugged” with the hex-socket screws provided. There are two reasons for this. When
suspending the loudspeaker from one end, the screws in the mounting/rigging points on the other
end transfer the load through the internal steel bracing to the bottom surface of the enclosure for
better support. Also if they are not plugged up, the holes can create air leaks in the enclosure that will
compromise the LF performance with reduced output and/or distortion.
11.2 Feet
The SLS and SBS loudspeakers are supplied with 4 rubber feet for use when mounted as free-standing
such as in portable applications. The feet have a cupped shape with a steel washer molded inside the
cup. This washer is necessary for the mounting screw to butt against when installed to help provide
structural rigidity to the feet.
To install the feet use the supplied 3/8”-16 thread, slotted head, filister head screws to mount the feet
on the enclosure to the mounting/rigging points. Sandwich one of the supplied 1-1/4” washers
between each foot and the enclosure surface to prevent the bottom of the foot from “dishing” into the
countersink. Tighten the screws snugly but do not over-tighten as this will pinch the rubber causing
stress and weakening the feet.
The feet are also used when stacking enclosures of the same size, such as an SLS960 full-range
loudspeaker on top of an SBS22. Four filister-head screws are screwed into the top of the bottom
enclosure. The cups in the feet of the top enclosure fit over the heads of these screws in the bottom
enclosure to help stabilize the top enclosure. This both aligns the enclosures and helps prevent the
top enclosure from “walking” because of bass vibrations or sliding from being accidentally bumped.
