Refer all servicing to qualified professionals. Servicing is required when the loudspeaker has been
damaged in any way, such as impact damage, liquid ingress or foreign object damage. In addition
the loudspeaker should be referred to qualified service personnel if there is any kind of malfunction.
Rigging, suspending and mounting should only be attempted by experience qualified professionals.
Incorrect usage can result in damage to equipment and property, injury and even death. Under
no circumstances should you attempt to rig, suspend or mount these speakers unless you are
fully qualified and certified to do so by relevant local, state and national authorities. If you are not
properly qualified or do not know of pertinent regulations consult qualified personnel for advice.
Consult a structural engineer before suspending a speaker system and ensure that the total
weight of your system can be held by the truss or mounting surface.
Inspect all mounting hardware before rigging, suspending or mounting. If there is any damage
or distortion to any mounting hardware do not proceed until any damaged hardware is repaired
or replaced.

About the SIGMA-X Series
2
Building on the reliable performance of the established SIGMA series, the new SIGMA-X features newly
designed front grilles and support materials to make the installation simply look and sound great. Improved
mounting and rigging options make SIGMA-X simple to install into almost any location. The improved
audio definition is also welcomed as SIGMA-X has been completely re-evaluated by the Wharfedale Pro
International R&D team.
New column models (Sigma-XV5 and XV9) also now feature HF compression drivers coupled to the innovative
mini EVO-Fold waveguide developed for the flagship WLA-1 Hybrid Curvature Array system.
Features
• Newly designed cosmetics
• Rotatable HF waveguides
• Re-evaluated performance
• Updated column models with HF drivers
• Column models with mini EVO-Fold waveguides
• EASE gll files available for download
• Supported with system diagrams
• Supported with downloadable FIR presets
• Easy fixings and brackets

SIGMA-X Series Optional Mounting Hardware
3
SIGMA-X8, X10, X12 and X15 can use the
optional WPB-1 or WPB-2 wall bracket
WPB-1 ASSEMBLY WPB-2 ASSEMBLY
M8 forged shoulder eye bolt
(User supplied, overhead
suspension rated and
certified)
SIGMA-X series can use M8 forged shoulder eye bolt ONLY. Be aware that lifting eye bolts at an angle
reduces the safe load. Always ensure the rigging hardware conforms to the safety standards and regulations
in your area.
Each primary load bearing suspension point shall
be rated for the total load. (A minimum 5:1 Design
Factor or Local Standard should be observed -
whichever is greater)
Secondary suspension point
M8 forged shoulder eye bolt
Working load limits:
No more than four (4) high (vertical)
The four (4) high vertical specification
represents a static ratio of 7:1
SIGMA-X Series Rigging
• Any installation should be inpected at regularly. Wear and corrosion may lead to deterioration.
• Always ensure that the suspension wires and mounting hardware are strong enough to support the weight
of the speaker / s.
• Always ensure rigging hardware (eye bolts / suspension wires) conform to the safety standards and
regulations in your area.
• For long term installation use a thread-locking compound.
• Do not attempt to bend or otherwise deform any rigging hardware.
• Never exceed 45 degrees from a right angle with suspension wires
• Wharfedale Pro cannot be held responsible for injury or damage caused by improper installation.
