JBL Professional VLA901Hi High Output Three-Way Full Range Loudspeaker

Product Overview

The JBL VLA901Hi is a high-output three-way line array module engineered for large-scale permanent installation in arenas, stadiums, outdoor amphitheaters, and houses of worship where extended throw distance, broad horizontal coverage, and sustained high SPL are non-negotiable requirements. Part of JBL's Variable Line Array system, it produces a maximum of 149.6 dB SPL at 1 meter from a single cabinet, with 90-degree nominal horizontal dispersion maintained from 400 Hz to 16 kHz across configurable array lengths. The combination of dual 15-inch Differential Drive® LF drivers, four 8-inch MF drivers, and six 1.5-inch HF compression drivers in a single cabinet gives the JBL VLA901Hi line array loudspeaker a transducer count and power-handling capacity suited to the highest-demand fixed-installation applications. For system designers specifying flyable large-venue line array systems, the VLA901Hi's 16-point M10 suspension hardware and optional WRC/WRX weather protection support both indoor permanent and outdoor exposed deployments.

Product Description

The VLA901Hi's low-frequency section uses two 2265H 15-inch Differential Drive® drivers, each with dual 3-inch voice coils. This configuration provides 1,000 W AES continuous LF power handling with a frequency response extending to 41 Hz (-10 dB) — unusually low extension for a line array module at this physical scale. Four 2169H 8-inch Differential Drive® midrange drivers with dual 3-inch voice coils handle 550 W AES continuous, providing the sensitivity and pattern control needed for coherent vertical coverage across array lengths. Six 2432H compression drivers with 1.5-inch exits and 3-inch voice coils cover high-frequency reproduction at 300 W AES continuous per cabinet, with the driver cluster arranged to maintain line source behavior through the upper treble.

The enclosure is constructed from 18 mm and 16 mm exterior-grade Baltic birch plywood with JBL's DuraFlex™ coating, rated to Mil-Std 810 and IPx3 in standard configuration. Optional WRC (weather-resistant coating) and WRX (extreme weather fiberglass) versions increase environmental protection for outdoor installations subject to direct precipitation exposure. The cabinet dimensions of 528.3 × 1,346.2 × 635 mm (20.8 × 53 × 25 in) and net weight of 107 kg (236 lb) reflect the full driver complement, but the high sensitivity — 98 dB (LF), 102 dB (MF), and 110 dB (HF) at 2.83 V / 1 m — minimizes the number of cabinets required to achieve system SPL targets.

Sixteen M10-threaded suspension points distributed across the cabinet support variable splay configurations required for arena and stadium main hangs. Barrier-strip input connectors provide secure termination for the high-current runs typical in large permanent installation systems. The VLA901Hi operates as a passive loudspeaker requiring external amplification; it is typically driven by Crown or Lab.gruppen amplifiers with JBL DSP presets loaded via HiQnet Performance Manager or BSS signal processing.

Key Features

• Dual 2265H 15-inch Differential Drive® LF Drivers — Dual 3-inch voice coils per driver; 1,000 W AES continuous LF handling with response to 41 Hz (-10 dB) for full-range coverage without a separate sub in moderate-demand applications.
• Four 2169H 8-inch Differential Drive® MF Drivers — 550 W AES continuous midrange handling; dual 3-inch voice coils provide the surface area and excursion for high-SPL midrange reproduction in long-throw array configurations.
• Six 2432H HF Compression Drivers — 1.5-inch exit, 3-inch voice coil; 300 W AES continuous per cabinet; arranged for line source HF behavior maintaining pattern control to 16 kHz.
• 149.6 dB Max SPL (1 m) — Highest output class for permanent installation line array modules; minimizes the number of cabinets required to achieve program SPL targets at distance.
• 90-Degree Nominal Horizontal Dispersion — Maintained from 400 Hz to 16 kHz; consistent audience coverage without excessive side spill in venues with reflective lateral boundaries.
• 41 Hz – 20 kHz Frequency Range (-10 dB) — Full-range line array coverage without mandatory subwoofer augmentation in applications where deep bass extension is secondary to intelligibility.
• 16 M10 Suspension Points — Distributed rigging hardware supports variable splay configurations for straight, curved, and compound array geometries.
• DuraFlex™ Finish with Mil-Std 810 / IPx3 Rating — Standard outdoor durability; optional WRC and WRX weather-resistant versions extend environmental protection for exposed outdoor permanent installations.
• Exterior-Grade Baltic Birch Plywood Construction — 18 mm and 16 mm panels; powder-coated 14-gauge perforated steel grille with acoustically transparent backing cloth.
• Barrier-Strip Input Terminals — Secure, high-current wiring connections appropriate for large permanent installation cable infrastructure.

Typical Applications

• Arena and stadium main hang line arrays for concert and sporting event reinforcement
• Outdoor amphitheater and festival stage permanent installation systems
• Large house of worship main arrays requiring long-throw coverage and pattern control
• Auditorium and performing arts center primary reinforcement systems
• Multi-purpose venues requiring a single high-output system for varied programming
• Government and civic assembly spaces requiring high-SPL, high-intelligibility coverage

Technical Specifications

Frequently Asked Questions

How many VLA901Hi modules are needed for a typical arena main hang? Array size depends on venue geometry, throw distance, SPL requirements, and desired vertical coverage angle. JBL's EASE and Array Morphing Tool (AMT) software models VLA system configurations. The Creation Networks team provides array design support for projects of this scale: creationnetworks.net.

What amplifiers are compatible with the VLA901Hi? The VLA901Hi is a passive three-way loudspeaker requiring external tri-amp or bi-amp amplification. It is commonly driven by Crown I-Tech HD or Lab.gruppen PLM series amplifiers with JBL factory DSP presets. Amplifier selection depends on LF, MF, and HF channel count and power budget per the system design.

Does the VLA901Hi require a subwoofer? The VLA901Hi extends to 41 Hz (-10 dB) and 50 Hz (-3 dB), providing usable bass extension for music and speech reinforcement. For productions requiring extended sub-bass output below 40 Hz or high-SPL bass reinforcement at large throw distances, the JBL VLA-C125S subwoofer module is the matched companion in the VLA system family.

Can the VLA901Hi be installed outdoors? The standard DuraFlex™ cabinet meets IPx3 and Mil-Std 810 ratings, suitable for sheltered outdoor environments. For fully exposed outdoor permanent installations subject to direct rain, the WRC weather-resistant coating or WRX fiberglass construction versions provide the appropriate protection level. Specify the correct variant at time of order.

How is the VLA901Hi rigged? The cabinet provides 16 M10-threaded suspension points (eyebolts not included) distributed for variable splay configurations. Rigging hardware, bridle sets, and array frames must be sourced separately and certified for the load. All aerial installations require engineering review and installation by certified rigging professionals.

What is the VLA901Hi's nominal impedance? The system presents a 4 Ω nominal impedance. Amplifier output stages must be rated for 4 Ω operation at the configured power levels. Consult the system amplifier datasheet and JBL DSP preset documentation for channel-by-channel impedance loading in tri-amp configurations.

What warranty and support are available for the VLA901Hi? JBL Professional products are supported by HARMAN's commercial warranty program. Creation Networks provides pre-sales design support, specification assistance, and post-sale service coordination for VLA system projects.
