L-Acoustics WIFOBUMP Rigging Frame for ARCS WIFO Systems
The L-Acoustics WIFOBUMP is a dedicated rigging frame developed for the vertical deployment of L-Acoustics ARCS WIDE and ARCS FOCUS loudspeaker systems. Designed as part of the ARCS WIFO rigging ecosystem, the WIFOBUMP provides a mechanical connection point for creating approved vertical flown arrays. It can also be used with L-Acoustics SB18m subwoofers in the configurations specified by the manufacturer.
For professional sound companies, production teams, touring applications, rental companies and installation professionals working with the L-Acoustics ARCS WIFO system, the WIFOBUMP is an important mechanical component for vertical array deployment. Unlike a loudspeaker enclosure, it does not produce sound itself. Its purpose is to provide the appropriate rigging interface for supported ARCS WIDE, ARCS FOCUS and SB18m configurations.
The WIFOBUMP belongs to the L-Acoustics ARCS WIFO generation of products and is now part of the manufacturer’s archived product documentation. L-Acoustics maintains archived documentation for former products, including the ARCS WIFO system. This makes the WIFOBUMP particularly relevant for owners and operators maintaining existing ARCS WIDE and ARCS FOCUS inventories that require compatible original rigging hardware.
What Is the L-Acoustics WIFOBUMP?
The L-Acoustics WIFOBUMP is a vertical-array rigging frame for the ARCS WIDE and ARCS FOCUS systems. It is engineered to mechanically connect supported loudspeaker and subwoofer configurations for flown vertical deployment.
The product documentation identifies the WIFOBUMP as a rigging frame for the ARCS WIDE/FOCUS system. L-Acoustics documentation also identifies it as a frame for flying ARCS WIDE, ARCS FOCUS or SB18m enclosures as a vertical array.
This makes the WIFOBUMP different from horizontal rigging accessories such as the WIFOLIFT and WIFOLIFTBAR. The WIFOBUMP is specifically associated with vertical deployment, while other ARCS WIFO accessories provide different rigging and stacking functions.
The WIFOBUMP is therefore best suited to professional users who already operate compatible L-Acoustics ARCS WIFO equipment and require the appropriate mechanical hardware to configure a supported flown system.
Designed for the ARCS WIDE and ARCS FOCUS System
The WIFOBUMP was developed as part of the L-Acoustics ARCS WIFO rigging system. ARCS WIFO refers to the ARCS WIDE and ARCS FOCUS loudspeaker family and its associated mechanical accessories.
The ARCS WIDE and ARCS FOCUS are passive loudspeaker enclosures designed for professional sound reinforcement applications. Their associated rigging system includes several dedicated components, including WIFOBUMP, WIFOLIFT, WIFOLIFTBAR, WIFOSOCK, WIFOTILT and WIFORIG.
Within that system, the WIFOBUMP provides the interface required for vertical flown configurations.
Because the WIFOBUMP is part of a specific manufacturer-approved rigging system, it should not be treated as a generic lifting frame. Compatibility, configuration, load limits and installation procedures must always be verified against the applicable L-Acoustics documentation for the actual system being deployed.
Vertical Deployment with WIFOBUMP
The main purpose of the L-Acoustics WIFOBUMP is to facilitate vertical flying of compatible ARCS WIFO enclosures.
According to the ARCS WIDE/FOCUS rigging documentation, a WIFOBUMP configuration can support approved vertical arrays of up to eight ARCS WIDE/FOCUS enclosures or four SB18m enclosures under the specified configuration limits.
The same documentation identifies a different approved limit when a CLAMP250 is used with the WIFOBUMP. In that configuration, the documented safe configuration is up to six ARCS WIDE/FOCUS enclosures or three SB18m enclosures.
These figures should not be interpreted as a universal load rating for every possible installation. L-Acoustics specifically requires users to model the intended system in SOUNDVISION and check the Mechanical Data section for stress or stability warnings before deployment.
The actual safe configuration depends on the system design, enclosure combination, rigging arrangement and deployment parameters.
WIFOBUMP and SB18m Compatibility
The WIFOBUMP is not limited exclusively to ARCS WIDE and ARCS FOCUS loudspeakers. L-Acoustics rigging documentation also identifies the WIFOBUMP as a frame for flying SB18m enclosures in vertical arrays.
The SB18m is a professional subwoofer that was designed to work with systems including ARCS WIDE and ARCS FOCUS. Its rigging system uses dedicated SB18MRIG coupling bars, which mechanically connect compatible SB18m elements and interface with the WIFOBUMP system.
This makes the WIFOBUMP useful when building a flown low-frequency or hybrid system based around compatible ARCS WIFO components.
For hybrid configurations containing both SB18m and ARCS WIDE/FOCUS enclosures, the manufacturer’s rigging documentation must be followed carefully. The documented system limits state that no more than four ARCS WIDE/FOCUS enclosures should be attached under SB18m subwoofers in a flown hybrid vertical configuration.
WIFOBUMP Construction
The WIFOBUMP is constructed from steel with an anti-corrosion coating. This construction is intended to provide a strong and durable mechanical component for professional loudspeaker rigging applications.
The manufacturer documentation records different WIFOBUMP weights associated with different revisions of the frame.
Earlier documentation lists the WIFOBUMP at approximately 10.5 kg / 23.1 lb, while a L-Acoustics technical bulletin documented an updated version weighing 11.5 kg / 25.4 lb. The update was associated with a change to the beam profiles and frame height beginning with specified serial numbers.
For this reason, buyers should verify the serial number and physical revision of an individual WIFOBUMP when exact dimensions or weight are important for transportation, inventory or system planning.
The later product information identifies the WIFOBUMP weight as 11.5 kg / 25.4 lb.

WIFOBUMP Rigging Configuration
A professional ARCS WIFO system can use several different mechanical accessories depending on the desired deployment.
The WIFOBUMP is the vertical rigging frame. WIFOLIFT and WIFOLIFTBAR are associated with horizontal flying configurations. WIFOSOCK provides a pole-mount interface for an ARCS WIDE or ARCS FOCUS enclosure, while WIFOTILT is used for specific stacking and angle adjustment applications involving ARCS WIFO enclosures and SB18m subwoofers.
This accessory-based approach allows the ARCS WIFO system to be deployed in different configurations while maintaining a dedicated mechanical interface for each application.
When selecting an accessory, it is therefore important to identify the intended deployment first. If the requirement is to fly an ARCS WIDE or ARCS FOCUS system vertically, the WIFOBUMP is the relevant L-Acoustics rigging frame.
Approved Vertical Array Configurations
L-Acoustics documentation for the ARCS WIDE/FOCUS system provides specific configuration limits for the WIFOBUMP.
For a vertical flown configuration using WIFOBUMP, the documented safe configuration includes up to eight ARCS WIDE/FOCUS enclosures or four SB18m enclosures.
When WIFOBUMP is used together with CLAMP250, the documented safe configuration is up to six ARCS WIDE/FOCUS enclosures or three SB18m enclosures.
These values come from the manufacturer’s rigging documentation and should be treated as configuration-specific rather than as a simple universal product capacity.
For professional installations, the complete array should be modeled using L-Acoustics SOUNDVISION before deployment. The Mechanical Data section should be checked for any stress or stability warning.
WIFOBUMP and CLAMP250
The CLAMP250 is another component of the ARCS WIFO rigging system. It can be used in certain configurations to connect an array to a truss.
The ARCS WIFO rigging manual explains that a CLAMP250 can be installed instead of a shackle when attaching a compatible array to a truss.
When WIFOBUMP is combined with CLAMP250, the allowable configuration changes. The manufacturer’s documentation identifies up to six ARCS WIDE/FOCUS enclosures or three SB18m enclosures for the documented configuration.
This is another reason why rigging accessories should not be mixed or substituted without consulting the applicable manufacturer documentation.
WIFOBUMP for Rental Companies
The L-Acoustics WIFOBUMP can be particularly useful for professional rental companies maintaining older ARCS WIFO inventories.
Companies that already own ARCS WIDE, ARCS FOCUS and SB18m enclosures may need original rigging accessories to keep their systems complete and deployable.
A missing rigging frame can prevent a complete loudspeaker system from being configured for its intended deployment. For this reason, original L-Acoustics rigging accessories can be valuable additions to rental inventories and replacement-stock programs.
When purchasing a used WIFOBUMP, rental companies should inspect the frame carefully and verify the condition of the steel structure, attachment points, locking components and associated hardware.
The serial number should also be recorded because different revisions of the WIFOBUMP exist.
WIFOBUMP for Touring and Production
Professional touring and event production environments require predictable mechanical integration between loudspeaker components and rigging hardware.
The WIFOBUMP was designed specifically around the ARCS WIFO system, making it suitable for supported vertical configurations involving compatible L-Acoustics enclosures.
For production companies using an existing ARCS WIFO inventory, having the appropriate WIFOBUMP frame can simplify the deployment of vertical arrays without relying on generic or non-approved mechanical hardware.
All flown systems should be installed by qualified personnel following the applicable L-Acoustics rigging documentation and local safety requirements.
WIFOBUMP for System Maintenance
Because ARCS WIFO is an archived product family, maintaining compatible original accessories can be important for users who continue operating existing systems.
L-Acoustics maintains an archive containing documentation for discontinued products, including ARCS WIFO. This provides an important reference for owners who need to verify original system components and technical information.
When purchasing an archived WIFOBUMP, it is advisable to confirm:
* The exact product designation.
* The serial number.
* The frame revision.
* The physical condition.
* The condition of attachment points.
* The presence and condition of required shackles or compatible hardware.
* Whether the frame is being supplied with its original documentation.
* Whether the frame is appropriate for the intended ARCS WIFO configuration.
Why Choose an Original L-Acoustics WIFOBUMP?
Using the manufacturer’s dedicated rigging hardware helps maintain the intended mechanical compatibility of the ARCS WIFO system.
The WIFOBUMP was designed specifically around L-Acoustics ARCS WIDE and ARCS FOCUS deployments rather than being a generic universal bumper.
For owners of existing ARCS WIFO systems, an original WIFOBUMP can therefore be an important component when restoring or completing a professional rigging inventory.
Its steel construction, dedicated attachment interface and compatibility with the ARCS WIFO rigging system make it a specialized accessory for professional sound reinforcement.
Important Rigging and Safety Information
The WIFOBUMP is a professional load-bearing rigging component. It must never be treated as ordinary audio equipment or installed without proper knowledge of loudspeaker suspension and mechanical safety.
L-Acoustics documentation specifies that users should read the applicable rigging manual before installing the product and should use the rigging accessories described in the manufacturer’s documentation.
The manufacturer also specifies that the intended system should be modeled in SOUNDVISION and that the Mechanical Data section should be checked for stress or stability warnings.
The ARCS WIFO rigging documentation also states that the WIFOBUMP should not be used with bridled suspension and that one load-bearing line should be used per pickup point in the documented flying configuration.
Always verify the current applicable documentation, local regulations, working-load requirements and site-specific safety conditions before suspending any loudspeaker system.
Original L-Acoustics Rigging Hardware
When purchasing an L-Acoustics WIFOBUMP, buyers should distinguish between the frame itself and a complete rigging package.
Depending on the seller and inventory, the product may be supplied as the WIFOBUMP frame only or together with associated hardware. Product photographs and the seller’s inventory description should therefore be checked carefully before purchase.
If you need a complete ARCS WIFO rigging solution, we can help you identify the appropriate accessories for your system configuration.
Condition and Inspection
The condition of used rigging equipment is especially important.
Before a WIFOBUMP is placed into service, the frame should be visually inspected for signs of deformation, cracks, corrosion, damage, unauthorized modifications or other conditions that could affect safe operation.
Attachment points and mechanical interfaces should also be inspected.
For used professional rigging equipment, documentation and inspection history can be just as important as cosmetic appearance.
If you are purchasing a used WIFOBUMP, request detailed photographs and confirm the serial number so that the exact revision can be identified.
Who Should Buy the L-Acoustics WIFOBUMP?
The WIFOBUMP is intended for professional users who operate compatible L-Acoustics ARCS WIFO equipment.
It can be relevant to:
* Professional sound rental companies
* Touring companies
* Live event production companies
* Concert sound providers
* Corporate AV companies
