Installation Instructions Using the
Embedded Nuts on the Loudspeaker
This loudspeaker has embedded nuts in the cabinet. Commercially
available fittings and eye bolts can be used with the nuts.
They use an M8 (screw length: 43 to 60 mm) thread hole.
WARNING
• Ask a professional technician to install the loudspeaker in a
suspended configuration.
• Remove the nuts from the embedded nuts in the loudspeaker, then
attach eye bolts.
• Do not use the loudspeaker with the screws removed. Doing so could
cause air to leak, adversely affecting audio quality.
• Make sure to suspend the loudspeaker from at least three locations.
Also, be sure to implement redundant safety and fall prevention
measures such as by using wires, etc.
• Make sure to use fittings, wires, walls, and ceilings that can sufficiently
handle the weight of the loudspeaker. Ask the dealer where the
commercially available fittings were purchased for further details.
• Always make sure to perform a safety check after installation, and
conduct periodic safety checks thereafter.
