L-Acoustics K1BUMP Bumper for K1 Speakers – Premium Flying Structure for High-Performance Line Array Systems The L-Acoustics K1-BUMP flying frame is an engineered solution designed specifically for the safe and efficient suspension of K1 and K1-SB loudspeaker enclosures in variable curvature vertical line array configurations. Tailored for professional touring, fixed installation, and high-end live sound applications, this system ensures precise alignment, enhanced structural integrity, and optimized acoustic performance across diverse venues—from stadiums to theaters. Key Features: - Durable main frame constructed from aerospace-grade aluminum alloy for long-term reliability under heavy load. - Central bar for balanced weight distribution and secure mounting points during hoisting operations. - Ball-locking pins (¼", ¾", and ⅜") provide quick, tool-free assembly while maintaining mechanical stability. - Dual-point hang and safety attachment points with 22 mm bolts and safety pins ensure compliance with industry safety standards. - Adjustable sling option enables compatibility with climbing hoist systems for complex rigging setups. - Integrated rack stabilizer allows seamless integration of LA-RAK touring racks, supporting modular storage and transport solutions. - Optimized geometry supports both straight and curved arrays, enabling dynamic coverage shaping for any venue layout. Detailed Description: This specialized flying structure transforms how sound engineers deploy K1 line array systems by offering a modular, adaptable, and robust framework. The K1-BUMP’s design emphasizes not only ease of setup but also precision in speaker orientation—critical for achieving uniform dispersion patterns and minimizing phase interference. Its lightweight yet rigid construction minimizes material fatigue over time, making it ideal for frequent setup/teardown cycles typical in touring environments. With its ability to support multiple configurations—including single-column stacks, curved arrays, or hybrid setups—it empowers audio professionals to tailor their installations to specific acoustic challenges such as high ceiling spaces, tight stage areas, or wide audience spreads. The inclusion of dedicated hardware like R-BLPs (round ball-locking pins) and T-BLPs (T-shaped locking pins) enhances connection security without compromising speed of deployment. Each component is tested rigorously to meet international safety benchmarks, ensuring peace of mind for users handling critical sound reinforcement tasks. Ideal Use Cases: Perfect for touring productions, corporate events, festivals, and permanent installations where flexibility, durability, and performance are paramount. Whether used in concert halls requiring immersive low-frequency response or outdoor arenas demanding extended coverage, the K1-BUMP delivers consistent results across varying environmental conditions. It's especially favored by sound designers working with large-scale PA systems who prioritize both aesthetic integration and technical excellence. User Feedback: Many professionals praise the K1-BUMP for its intuitive design and reliability in high-stress environments. Users often highlight the reduced rigging time compared to traditional methods and the confidence gained from knowing each connection point is secured using proven locking mechanisms. Engineers appreciate how it simplifies the process of creating curved arrays without sacrificing structural safety—a common challenge in complex installations. Frequently Asked Questions: What makes the K1-BUMP different from standard speaker flying frames? Unlike generic rigging solutions, the K1-BUMP is purpose-built for L-Acoustics’ K1 series enclosures, ensuring perfect fit, optimal balance, and seamless integration with existing accessories like LA-RAK racks. Its unique combination of adjustable slings, multiple pin types, and dual safety points offers superior versatility and compliance with modern rigging protocols. Can it be used with other speaker models? It is exclusively designed for K1 and K1-SB enclosures. Using it with non-compatible units may compromise safety and performance. Is it suitable for outdoor use? Yes, the frame is built to withstand prolonged exposure to weather elements when properly maintained, though regular inspections are recommended for extended deployments. How does it improve sound coverage? By enabling variable curvature arrangements, the K1-BUMP helps shape the vertical dispersion pattern to match room acoustics—enhancing clarity, reducing spill, and improving audience uniformity.
