Martin Audio WPL – 2x12" Bi-Amp Large Format Line Array

Product Overview

The Martin Audio WPL is a 3-way bi-amp large format scalable line array loudspeaker designed for the highest-output commercial and touring applications — festivals, stadium main hangs, arena installations, and premier concert hall systems. Dual 12" drivers in an all-horn, maximum-efficiency design deliver exceptional SPL with the sonic signature and pattern control expected of a flagship commercial line array system. As the largest enclosure in the Wavefront Precision platform, the WPL integrates with Martin Audio iKON multi-channel Class D amplification and DISPLAY software to apply per-segment scalable resolution optimisation across arrays of up to 24 enclosures. AV system designers and production integrators specifying for the largest venues will find the WPL provides the output headroom, directivity precision, and system integration depth required for mission-critical large venue AV deployments.

Product Description

The Martin Audio WPL represents the full-scale member of the Wavefront Precision commercial line array system family, engineered for venues and productions where output, throw distance, and sonic precision are all non-negotiable. The all-horn, maximum-efficiency cabinet design maximises acoustic output from the dual 12" LF drivers, with a 3-way bi-amp active crossover delivering independent amplifier channels to the LF section and the MF/HF section for precise frequency response, time alignment, and transducer protection across the full operating range. The 90° horizontal constant directivity pattern provides consistent coverage across wide audience planes without off-axis degradation, which is critical in wide stadium bowl and arena configurations. Scalable resolution, applied through Martin Audio's DISPLAY acoustic prediction software, divides the array into individually optimised segments, assigning unique delay, level, and EQ parameters to each group of enclosures. This per-segment approach eliminates the coverage inconsistencies inherent in conventional large-format line arrays and delivers uniform SPL and tonal accuracy from the front of house to the rear of the most complex audience geometries. The integral 3-point rigging system accommodates arrays of up to 24 enclosures, with discreet side handles for rapid, precise splay angle setting during hang assembly. WPL systems are deployed in stadium touring, festival main stages, arena concert halls, government performing arts facilities, and premium fixed installation environments where the highest standards of commercial line array system performance are required.

Key Features

• All-Horn Maximum-Efficiency Design — Achieves the highest acoustic output per watt of any Wavefront Precision enclosure, reducing amplifier power requirements for large arrays.
• 3-Way Bi-Amp Configuration — Independent amplifier channels for LF and MF/HF deliver precise crossover control, time alignment, and transducer protection at full system load.
• Dual 12" LF Drivers — High-excursion large-format drivers produce the sustained SPL and low-frequency extension needed for stadium and arena scale applications.
• Scalable Resolution Technology — Per-segment DISPLAY-driven optimisation delivers coverage uniformity that conventional large-format line arrays cannot match.
• 90° Horizontal Constant Directivity — Consistent tonal response and level control across wide audience coverage zones in stadium and arena configurations.
• DISPLAY Software Integration — Full acoustic prediction, splay calculation, per-segment DSP parameter loading, and system verification in a single software environment.
• iKON Multi-Channel Class D Amplification — Dedicated amplifier platform with onboard DSP and native DISPLAY integration for complete system control.
• Integral 3-Point Rigging, Up to 24 Enclosures — Larger maximum array size than other WP enclosures; discreet side handles for rapid splay angle control.
• Compact and Lightweight for Format Size — Optimised cabinet dimensions reduce rigging load compared to equivalent-output conventional large-format enclosures.

Typical Applications

• Stadium and arena main hang — touring and fixed installation
• Festival main stage and outdoor large venue
• Concert hall and performing arts centre flagship system
• House of worship — large campus and multi-venue facilities
• Government civic auditorium and convention centre
• Broadcast studio and live production venue

Technical Specifications

Frequently Asked Questions

How does the WPL differ from the WPC in a large venue specification?

The WPL uses larger 12" dual drivers, an all-horn maximum-efficiency cabinet, a 90° horizontal pattern (vs 100° on WPC), and supports arrays up to 24 enclosures vs 16 for the WPC. It is specified for stadium, festival, and arena-scale applications where the WPC's output ceiling is insufficient.

How many WPL enclosures can be rigged in a single array?

The WPL's integral 3-point rigging system supports up to 24 enclosures per hang, enabling coverage of the largest venue and arena footprints.

What amplifier platform does the WPL require?

The WPL requires bi-amp external amplification. Martin Audio's iKON multi-channel Class D amplifier series is the specified platform, providing dedicated LF and MF/HF channels per enclosure with onboard DSP and native DISPLAY software integration.

What is the horizontal coverage pattern?

The WPL delivers 90° constant directivity horizontally, maintaining consistent level and tonal response across the full coverage zone.

What is scalable resolution and how does it benefit a stadium system?

Scalable resolution allows DISPLAY software to divide the array into independently processed segments, each with unique delay, level, and EQ. In a stadium bowl where audience geometry changes radically from front to rear, this means every zone receives correctly optimised coverage rather than a compromise setting applied uniformly to the full hang.

Can the WPL be used in a fixed concert hall or performing arts centre?

Yes. The WPL is fully suited to permanent installation in concert halls and performing arts centres where maximum output, long throw, and exceptional sonic fidelity are all required specifications.

What warranty applies to the Martin Audio WPL?
