The L-Acoustic A15-BUMP Flying Frame is a specialized rigging accessory engineered to enable the vertical array deployment of specific A15 Focus and KS21 subwoofer cabinets. This robust, purpose-built frame serves as a structural intermediary, securely attaching to flown rigging points and providing the correct mechanical interface to safely suspend a column of these enclosures. Its primary function is to facilitate the creation of compact, high-output vertical arrays—often referred to as "bumps" or "towers"—that are ideal for side-fill systems, delay towers, or main arrays in venues with specific sightline or coverage requirements. The design ensures that the loudspeakers are held at the manufacturer-specified angles and orientations to achieve the intended acoustic coupling and wavefront propagation.

Constructed from high-grade steel, the frame is built to handle the significant weight and dynamic forces of multiple active loudspeakers in a flown configuration. Its geometry is precisely calculated to maintain the correct inter-cabinet angles for the A15 Focus modules while also integrating the low-frequency extension of the KS21 subwoofer when used in a full system. The frame includes integrated safety lock pins and multiple rigging points that interface directly with standard flying hardware, ensuring a secure, redundant connection that meets rigorous safety standards for overhead suspension. Every component is finished for corrosion resistance, guaranteeing reliability in various touring and installation environments.

The A15-BUMP simplifies the logistical and mechanical challenges of deploying a hybrid array. By providing a single, pre-engineered frame, it drastically reduces onsite assembly time and minimizes the potential for rigging errors. It represents a critical component within the L-Acoustic ecosystem, allowing system designers and technicians to leverage the sonic performance of the A15 and KS21 in versatile, space-efficient vertical configurations. This frame effectively transforms individual, powerful loudspeakers into a unified, flyable array system, offering enhanced control over sound dispersion and system scalability for demanding professional audio applications.
