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.

Acheron Floor Mount Bracket Kit Contents

The Acheron floor mount kit (PN 40.188.026.01) includes the 
following parts.

NOTE: 

The 3/8-16 x 1.5-inch screws required 

for securing the floor mount brackets to the 

Acheron are shipped with the loudspeaker installed in 
the two bottom screw holes on each side (four total).
