A15 Wide: High-Performance Passive
Line Array Speaker for Professional Sound Reinforcement The L-Acoustics A15 Wide is a versatile, 2-way passive loudspeaker engineered for exceptional clarity, coverage, and deployment flexibility across diverse live sound environments. Designed as part of the acclaimed A15 family, this medium-throw speaker delivers high-fidelity audio performance while maintaining an intuitive setup process—ideal for touring productions, fixed installations, and large-scale events. With its optimized directivity control and robust build quality, the A15 Wide ensures consistent sound pressure levels and seamless integration into both vertical line arrays and standalone configurations. Key Features: - 30° horizontal dispersion enclosure with Panflex technology for adaptive beamwidth adjustment - 15-inch low-frequency driver paired with a 3-inch high-frequency compression driver - Bass-reflex port design (L-Vents) for extended low-end response down to 29 Hz when used with KS21 subwoofers - Rated power handling of 600 watts with peak capability up to 2400 watts - Maximum SPL of 141 dB at 1 meter, ensuring powerful output even in expansive venues - IP55-rated weather resistance for outdoor use or challenging indoor conditions - Durable Baltic birch plywood cabinet with anti-corrosion steel rigging hardware - Flush-mounted two-point suspension system for safe flying or ground stacking - 8 Ω nominal impedance and dual SpeakON inputs for reliable signal transmission Detailed Description: Engineered for maximum versatility, the A15 Wide excels in applications ranging from front-of-house reinforcement to side-fill, infill, and delay systems. Its unique 30° enclosure allows compact vertical arrays to maintain optimal sightlines while delivering wide horizontal coverage—perfect for stage-perimeter setups or audience-centric configurations. The integrated Panflex waveguide enables precise control over directivity, offering symmetric patterns such as 110°/70° and asymmetric options like 90°, making it adaptable to irregular room geometries or complex acoustic environments. When combined with A15 Focus units, the system forms a scalable line array ideal for mid-to-large venue deployments, providing uniform coverage and minimal phase distortion. For smaller spaces or temporary setups, the A15 Wide functions independently as a point-source solution, suitable for pole mounting or portable staging. The inclusion of a dedicated low-frequency extension via the KS21
Subwoofer enhances the overall sonic envelope, extending the usable bandwidth to just 29 Hz—a rare feature in this class of passive speakers. Use Cases: This speaker shines in professional live sound scenarios including concerts, festivals, corporate events, theater productions, and permanent installations. Whether deployed as part of a flown line array for crowd-filling coverage or positioned as a flexible fill source on stage, the A15 Wide offers consistent performance regardless of application. It’s particularly effective in venues where visual aesthetics matter—thanks to its sleek design and acoustically neutral fabric grille—and remains resilient under demanding environmental conditions due to its IP55 rating. Sound engineers appreciate its predictable off-axis response and stable frequency behavior across all directivity settings, reducing the need for complex equalization during setup. User Feedback: Users consistently praise the A15 Wide for its balance between power and precision. Many note how easily it integrates into existing systems without compromising tonal accuracy, especially when paired with complementary subwoofers. Touring sound professionals highlight its reliability in long-term deployments, citing the rugged construction and secure rigging points as key advantages. Audio technicians also commend the flexibility of Panflex technology, which simplifies adjustments for different audience layouts without requiring additional equipment or reconfiguration. Frequently Asked Questions: What makes the A15 Wide stand out from other passive line array speakers? Its combination of adaptive directivity, robust construction, and seamless compatibility with the A15 Focus and KS21 series sets it apart. Unlike many competitors, it maintains excellent frequency response stability across multiple angles—a critical factor for consistent sound quality throughout the listening area. Can it be used in outdoor environments? Yes, thanks to its IP55 protection rating, the A15 Wide performs reliably in wet or dusty conditions, making it suitable for open-air events or temporary installations exposed to the elements. Is it compatible with other L-Acoustics products? Absolutely—it’s designed to integrate effortlessly into any A15-based system, enabling scalable solutions from small to massive configurations using standard connectors and rigging hardware. How does the Panflex feature improve performance? Panflex allows real-time adjustment of the high-frequency dispersion pattern, ensuring that the sound field matches the audience layout—whether it's a narrow hall, wide stage, or irregularly shaped room—resulting in more uniform coverage and fewer acoustic anomalies. What is the recommended subwoofer pairing? For optimal low-end extension and system coherence, the KS21 subwoofer is strongly recommended, offering deep bass response down to 29 Hz and enhancing the full-range performance of the A15 Wide.
