CHAPTER 5: MOUNTING
Strategically placed 3/8-inch threaded points on the side
corners of the Acheron cabinet allow the unit to be secured
to floors with uptilt or downtilt using the optional mounting
brackets. The Acheron can also be mounted on top of the
Acheron LF loudspeaker, also with uptilt or downtilt, using
the optional stacking brackets. Both brackets are available
for purchase from Meyer Sound.
Important Safety Considerations!
When installing Meyer Sound loudspeakers and subwoof-
ers, the following precautions should always be observed:
■ All Meyer Sound products must be used in accordance
with local, state, federal, and industry regulations. It is
the owner’s and user’s responsibility to evaluate the reli-
ability of any mounting and rigging method for their
application. Mounting and rigging should only be carried
out by experienced professionals.
■ Use mounting and rigging hardware that has been rated
to meet or exceed the weight being hung.
■ Make sure to attach mounting hardware to the building's
structural components (studs or joists), and not just to
the wall surface. Verify that the building's structure and
the anchors used for the installation will safely support
the total weight of the mounted loudspeakers.
■ Use mounting hardware appropriate for the surface
where the loudspeaker will be installed.
■ Make sure bolts and eyebolts are tightened securely.
Meyer Sound recommends using Loctite
®
on eyebolt
threads and safety cables.
■ Inspect mounting and rigging hardware regularly. Imme-
diately replace any worn or damaged components.
Acheron and Acheron LF Side Screws
The Acheron and Acheron LF ship with four 3/8-16 x 1.5-
inch screws installed on each loudspeaker side (eight total).
These screws and threaded points are used to secure the
floor mount and stacking brackets to the loudspeakers.
CAUTION: If the Acheron side screws are
removed to install the brackets, make sure to
always reinstall the screws, and tighten them
securely. If the side screws are not present when
using the loudspeakers, air leakage will result, which
will adversely affect frequency response.
ACHERON FLOOR MOUNT BRACKETS
The Acheron floor mount brackets secure Acheron loud-
speakers to floors with downtilt and uptilt angles of
0–18 degrees (in 3-degree increments). The floor mount
brackets should also be used with Acheron LF loudspeakers
when stacking an Acheron on top of the Acheron LF.
