Overview

RL4 Line Source Element | The Intelligent Choice for Medium-to-Small Sound Reinforcement

Acoustic Design: Laser-Sharp Directivity, Pristine Transducer Detail

RL4 Optimized for small-to-medium line source deployments, RL4 maintains an exceptionally linear tonal balance even over extended throw distances, combining an extraordinary usable bandwidth with commanding dynamic headroom for unfailing acoustic consistency.

Its mechanical and acoustic architecture guarantees two signature advantages: uncompromising directivity control for razor-sharp audience coverage, and an ultra-compact, weight-optimized footprint for agile adaptability across diverse event profiles.

Operating on a two-way passive topology, the internal crossover logic remains minimalist and high-efficiency to preserve maximum phase coherence and absolute sonic transparency. The enclosure features a fully symmetrical, coplanar transducer layout: dual 8-inch neodymium LF drivers are arranged in a bipolar configuration to deliver a tight, high-impact low-frequency contour. Centered between them is a premium HF compression driver featuring a 1.4-inch exit and a 3-inch voice coil, coupled directly to a proprietary line source waveguide.

This advanced wave-shaping device enforces seamless inter-element coupling to generate a perfectly coherent, isobaric vertical wavefront, granting the system a 90°–110° adjustable horizontal constant directivity that redefines coverage precision.

Rigging & Durability: Tactical High-Output, Compact Power

RL4 Flexibility defines its system integration. RL4 excels as a high-performance standalone system for small-to-medium arrays, or scales effortlessly alongside RL15、RL2 to provide exact sonic matching and fill coverage—making it the definitive choice for center clusters or delay lines.

Streamlining onsite workflows, the cabinet integrates a captive rigging system forged from premium stainless steel and aerospace-grade aluminum alloy. This fast-lock hardware folds flush into the enclosure for rapid, complex-free deployment. Splay angles scale smoothly from 0° to 10° with precision-calibrated 1° increments to sculpt the exact coverage geometry required.

Built for relentless road life, the enclosure is crafted from premium multi-ply birch plywood protected by a rugged polyurea coating that stands resilient against UV degradation and impact shocks.Engineering precision extends to the protective front grid: a rigid metal grille shields internal components, backed by an acoustically transparent, hydrophobic textile that seals out humidity without colorizing the sound.Ergonomic, flush-mounted handles on the side panels complete the system for rapid, fatigue-free handling.

Applications & Ecosystem: Fluid Adaptability, Extended Potential

RL4 Integrating multiple patented technologies and coupled with dedicated amplified controller DSP presets and real-time thermal/over-excursion protection algorithms, RL4 guarantees flawless sonic purity across any environment—from civic auditoriums, arenas, and theaters to demanding global concert touring.

Deploying the system with the RL4 SUB flyable subwoofer extends both low-frequency contour and wavefront control, scaling the ecosystem to conquer large-scale venues with absolute acoustic sovereignty.
