Hybrid Ground Stack Rigging for the MFLA-MK3 + VS21
The BASSBOSS VSLA Bracket Kit provides a factory-engineered method to mount one MFLA-MK3 line array cabinet directly atop a horizontally positioned VS21 subwoofer. This hybrid rigging solution is ideal for applications where flying is not possible and vertical stack height must be minimized. The bracket system locks the two components together into a stable, roadworthy configuration with consistent angle and phase alignment.
Powder-coated steel construction ensures long-term durability in touring, install, or rental scenarios, while the custom-fit contouring allows for fast setup without guesswork or spacing concerns. This is the official BASSBOSS solution for tightly coupled, ground-based MFLA deployments with the VS21.
Factory-Matched Mounting for Compact MFLA Arrays
The VSLA kit eliminates the need for generic rigging adapters or spacers by providing a BASSBOSS-verified link between the MFLA-MK3 line array top and the VS21 subwoofer in its horizontal orientation. That makes it a go-to solution for venues, DJs, or integrators looking to deploy powerful full-range MFLA output from ground level.
Real-World Applications and Use Cases
- Perfect for mobile DJ rigs that need the MFLA’s performance in venues where flying is not an option.
- Great for indoor venues or installs with ceiling height limitations or rigging restrictions.
- Designed for rental houses deploying modular ground stacks for fast setup/strike scenarios.
Where the BASSBOSS VSLA Bracket Kit Excels
- Mobile DJ Ground Stacks: Enables compact, road-ready setups without requiring flown arrays.
- Low-Ceiling Venues: Ideal for clubs, churches, and halls where suspension is restricted or not allowed.
- Fast Setup Environments: Provides a plug-and-play rigging solution for rental and touring applications.
- Phase-Accurate Coupling: Ensures alignment between MFLA output and the horizontally-positioned VS21 sub.
- Official BASSBOSS Integration: Certified connection method that preserves warranty and system stability.
How to Deploy the VSLA Bracket Kit in the Field
Deployment begins by positioning the BASSBOSS VS21 subwoofer horizontally on a stable surface. The VSLA brackets are then mounted directly to the sub’s top surface using factory-aligned locations. Once secured, a single MFLA-MK3 cabinet is attached above using the mating bracket interface—providing a fixed, locked-in connection between the two components.
This assembly maintains phase integrity and vertical symmetry between the subwoofer and line array top. The result is a compact, integrated system that performs like a traditional flown rig—without the need for rigging points, motors, or stands.

Frequently Asked Questions
Can the VSLA bracket kit support multiple MFLA cabinets?
No. The VSLA kit is designed specifically for mounting one (1) MFLA-MK3 cabinet to a single horizontal VS21 subwoofer. Stacking additional tops requires different support methods.
Is this bracket compatible with other subwoofers?
No. The VSLA is precision-built for the BASSBOSS VS21 when used in a horizontal position. It will not align with other models like the DJ18S or SSP218.
Do I need tools to assemble the bracket kit?
Basic tools may be required for securing the brackets, but the mounting points are pre-aligned with BASSBOSS hardware—no fabrication or retrofitting necessary.
Will this affect phase alignment between the sub and top?
No. The bracket maintains proper acoustic coupling and mechanical alignment between the VS21 and MFLA-MK3, preserving the system’s phase coherence.
Can this be used in permanent installations?
Yes. The VSLA kit is suitable for both mobile and fixed installs where flown arrays aren’t feasible. Always follow BASSBOSS guidelines for structural load and safety.
