WPL

2 x 12" Bi-amp Three-way Line Array

WPL – Large-Format Precision, Scaled for Stadium and Festival Power

WPL is a 3-way, bi-amped, large-format line array with dual 12” LF, scalable resolution optimisation, and the ability to deliver stadium-level and large festival output with extraordinary control.

At just 64kg [116lbs] its power output to weight relationship provides additional efficiency in trucking space and speed of deployment.

From Q2 2026, WPL systems are designed to withstand tougher environmental conditions, feature LED circuit visibility, and enjoy blazing-fast DISPLAY 3 optimisation software with enhanced LF control.

If fidelity, precision and ROI matters, this is the moment to choose WPL.

Dual Hybrid® Horn LF: Maximum Projection, Minimum Waste

Edit Content

At the heart of WPL’s low-frequency performance is Martin Audio’s Hybrid® horn technology — combining the punch and projection of a horn with the extension of a bass-reflex design.

Key advantages include:

~4dB efficiency improvement over direct radiator LF designs
Superior LF throw and warmth over long distances
Better pattern control down to 150Hz
Reduced spill at the sides and rear of the array

The LF section uses 2 × 12” neodymium drivers, each front-loaded by hyperbolic horns and rear-loaded by a ported chamber. A differentially flared port minimises turbulence for cleaner, more musical low-frequency reproduction. Drivers are engineered for high excursion, forced-air cooling, and low power compression, ensuring consistent output from the first note to the last.

Patented Horn-Loaded Midrange: The Signature WPL Sound

Edit Content

WPL’s midrange is central to its power, clarity and vocal intelligibility — and is one of its greatest competitive advantages.

Using 2 × 6.5” cone drivers with toroidal phase bungs on a fully horn-loaded, constant directivity waveguide, this section:

Maintains 90° horizontal pattern control with minimal variation across the 300Hz–4kHz band
Reproduces the entire vocal range on a single diaphragm for superior tonal consistency
Delivers higher output and cleaner projection than direct radiator alternatives
Reduces distortion through a low compression ratio throat design
Ensures smoother horizontal response via the patented HiBlade™ waveguide

The result is unmistakable: smooth, powerful, and highly intelligible vocals that carry effortlessly across vast audience areas.

Ultra-Clean, Extended HF with True Line-Array Behaviour

Edit Content

For high frequencies, WPL uses 3 × 1” exit neodymium compression drivers, each on its own horn with genuine 90° constant directivity.

This architecture — combined with the high 4kHz crossover enabled by the mid horn — provides:

Significantly lower HF distortion than large-format compression driver designs
Cleaner reproduction exactly where human hearing is most sensitive
More open, extended top-end
No “break-up region” harshness common in larger diaphragms
Patented kite-shaped horn wedges that flatten the wavefront for true line-array summation

Put simply: highs stay pristine, controlled, and fatigue-free, even at high SPL levels.

Fast, Safe, Rigger-Approved Deployment

Edit Content

WPL features a robust three-point rigging system for speed, safety, and simplicity.

Suspends up to 24 enclosures
DISPLAY sets angles from 0°–7.5°
Full compliance with BGV-C1 and other global standards

Front rigging:

Over-extending hinges give generous finger-room and safer pinning — especially valuable when dolly angles aren’t level on festival sites.

Rear rigging:

Splay angles can be pinned while the array is still closed on the dolly. Once flown, the boxes open automatically to the pre-set angles, saving valuable build time. Deployment is quick, predictable, and confident — exactly what touring crews demand.

Scalable Resolution: Flexible Control, Coverage and Consistency

Edit Content

Wavefront Precision systems adopt a unique principle of control, coverage and consistency you can scale on your terms.

Using external iKON multi-channel amplifiers, each array can be deployed at different resolution levels. More amplifier channels equal more individually driven enclosures — and that unlocks finer optimisation, tighter SPL consistency, and more accurate room control through DISPLAY.

Even at lower resolution the acoustic design delivers exceptional performance. But scalable resolution means you can:

Match system design to budget targets without compromising audio quality
Upgrade resolution over time, simply by adding amplifiers
Dynamic deployment within a venue or site, with the main PA at higher resolution and delays or outfills at lower resolution

It’s performance made flexible, predictable, and financially accessible.

DISPLAY 3 Optimisation: Faster with Higher Precision

Edit Content

From Q2 2026, Wavefront Precision systems integrate seamlessly with DISPLAY 3, Martin Audio’s new-generation 3D optimisation software — 27,000× faster than DISPLAY 2 and accurate to within ±1 dB of measured performance.

Through a combination of mechanical angle optimisation and advanced DSP filtering, DISPLAY 3 software:

Optimises the sound to meet SPL and frequency response target goals set by the user, by determining the necessary configuration and output of the array to produce that result.
Assesses and minimises influence of non-audience areas within a venue or space, while simultaneously maximising sound coverage and consistency for the audience area, increasing clarity and intelligibility.
Delivers improved control of low frequency that is meaningful in itself, and also open doors to increased flexibility of line length.
Utilises Hard Avoid® feature to intelligently avoid audio reflections of problem surfaces like ceilings or balcony edges or significantly reduces sound in a given area like below or behind an array, or beyond an audience zone for mitigating noise pollution, by up to 30dB.

Getting fast and accurate results for a complete system with the freedom to quickly refine ensures optimal sound system deployment for every venue.

Array DSP parameters calculated by DISPLAY are easily uploaded to the iKON amplifiers via Ethernet, using Martin Audio’s VU-NET™ real-time control and monitoring software.

Amplification, DSP & Networking: Built as a Complete System

Edit Content

Wavefront Precision line arrays are designed as complete systems with dedicated, high-performance iKON multi-channel Class D amplifiers, capable of very high power outputs and feature high-speed Ethernet communication for system control and monitoring via VU-NET, plus Dante™ digital audio networking.

With the option to transmit digital audio over a single CAT5 cable, quality is maintained over long cable runs and integration with other devices in the sound system is straightforward.

Furthermore, from Q2 2026, every Wavefront Precision enclosure is now smarter as they feature an LED indicator that can be illuminated via VU-NET software to identify its circuit location.

iKON amps provide powerful DSP processing of up to 1000 FIR filter taps @ 48kHz on each output channel. This high number of taps is essential to implement DISPLAY’S wide bandwidth optimisation capabilities.

The complete system approach not only guarantees that Wavefront Precision arrays perform repeatedly and effortlessly to their design maximum, but also that they are compatible worldwide.
