WPM is a highly versatile, ultra-compact Wavefront Precision line array, engineered for small to medium-scale venues where superb fidelity, consistent coverage and precise control are essential. Despite its small footprint, WPM delivers peak SPL of 130 dB (136 dB with crest factor 4) and can project over 35 metres (115 ft), making it capable of filling up to 3,000-seat venues with live music, corporate events, AV installations and Houses of Worship.
Its compact size and light weight make WPM the go-to choice for small theatres, ballrooms, concert halls, and multi-purpose spaces, while retaining the high-output performance expected from Martin Audio’s flagship line array technology.
WPM 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 WPM.
Features
- 2-way passive, 2 x 6.5” mini line array
- Scalable resolution for advanced array control
- External, dedicated, multi-channel Class D amplification
- Industry-leading DISPLAY software interacts with DSP for highly-accurate results
- Fast, integral 3-point flying systems for up to 16 enclosures
- Side and rear handles for ease of handling and setting splay angles
- 100° horizontal constant directivity pattern control
Benefits
- Consistent coverage achieved ‘straight-out-of-the-box’
- DISPLAY intelligent software reduces set-up time and eliminates trial-and-error
- Improved audience coverage with reduced sound-spill
Applications
- Touring sound reinforcement for small and medium-size venues
- Fixed installations in concert halls, theatres, ballrooms and HoW
- Sports stadium, arena installations & corporate AV events
LF Section – Integrated Horn Walls for Maximum Efficiency
- 2 × 6.5” neodymium drivers
- Side-mounted within the HF horn walls to preserve horn continuity
- Moulded diaphragms maintain seamless horn profile, eliminating acoustic cavities
- Demodulation rings in the motor system reduce distortion and enhance mid-band output
This arrangement allows WPM to deliver high-output, controlled low frequencies in a remarkably compact enclosure — a major advantage over conventional cone designs at this size..
HF Section – Precision by Name, Precision by Nature
- 3 × 1.4” aluminium dome drivers
- Each driver coupled to the horn throat via a short waveguide
- Delivers 100° horizontal constant directivity
- Produces clear, detailed, and coherent high frequencies across the coverage area
The result is exceptional intelligibility and uniformity, ensuring that vocals, speech, and instrumentation remain crisp and present even in the tightest spaces.
WPM is designed for quick, repeatable deployment:
- Lightweight, compact enclosures reduce load-in and setup times
- Ergonomic rigging points allow secure, efficient array assembly
- Compatible with other Wavefront Precision arrays for multi-role deployment
Whether flying as a small main array or supporting larger systems as front-fill or delay, WPM provides predictable, high-quality coverage every time.
WPM enclosures now feature improved construction methods, improved paint and improved metalwork to make them more hardwearing.
- IP rating of IP54
- Corrosion resistance
- High heat, cold temperature and humidity protection
- UV stability protection
These improvements make WPM reliable and resilient for touring, live performance and fixed-install environments alike.
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.
Wavefront Precision systems integrate seamlessly with DISPLAY 3, Martin Audio’s new-generation 3D optimisation software — super fast and accurate to within ±1 dB of measured performance. Read More
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.
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, 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.
WPM combines:
- Compact size and light weight
- DISPLAY driven optimisation with scalable resolution
- Controlled low-end punch and coherent high frequencies
- Touring and installation-ready ruggedness
It’s the ultimate ultra compact line array solution, giving rental houses and integrators exceptional coverage, clarity, and deployment flexibility in the smallest possible footprint.
