Overview
FS4 High-Performance Subwoofer | Dedicated Flying Sky-Bass Array Element
Acoustic Design: Deep Extension, Pristine Linear Reproduction
FS4 Anchors premium outdoor events as a specialized flying sky-bass deployment, natively coupling with the RL4 system through an advanced band-pass acoustic architecture to unleash explosive low-frequency energy.
The enclosure houses a custom 18-inch long-excursion transducer developed in exclusive collaboration with B&C Italy. Equipped with a 4-inch (100 mm) voice coil, a waterproof cone, and a triple-roll surround, it handles a massive 2400W program power to secure relentless dynamic headroom.
Utilizing a high-grade neodymium motor topology combined with a dual-silicone spider design ensures maximum linear excursion. This magnetic mastery delivers exceptional transient sharpness and superior low-end dynamics, executing authentic, hard-hitting bass reproduction that meets the strict textural demands of high-end, mid-to-small scale deployment zones.
Structural Resilience: Integrated Fleet Rigging, Tour-Grade Endurance
FS4 Adapting to complex stages with absolute installation versatility, the cabinet integrates a flush-mount aluminum alloy rapid-rigging system. Locking seamlessly into the structural framing, it slashes setup times, supporting both flown sky-bass configurations and ground-stacked arrays while fusing into a visually and acoustically unified system when ground-stacked with the RL4.
Cabinet durability remains uncompromised, constructed from premium high-density multi-ply birch and coated in a rugged, wear-resistant black polyurea finish to guard against high-impact transit wear. The front steel grille features a reinforced rib pattern merged with an optimized high-porosity layout, which aggressively lowers port airflow resistance, enhances wave penetration, and mitigates turbulence noise to ensure zero vibration or rattle at extreme SPL.
Tactical Ergonomics: Systemic Calibration, Global Field Adaptability
FS4 Focusing heavily on field safety and crew ergonomics, each side panel integrates flush-mount heavy-duty handles for fluid handling. The top panel features dual interlocking recesses machined to perfectly index with the corresponding high-friction bottom feet of the nesting enclosure, preventing array shifting during high-vibration stacking to maximize ground safety.
Primary applications encompass premium outdoor and indoor concert touring, engineered specifically to supplement the sky-bass infrastructure. When integrated into an RL4 matrix, it optimizes wavefront coherence, enriches musical expression, and locks in total system integrity to deliver a deeply immersive, high-impact low-frequency experience.
