WPS

Features and Applications

Product Details WPS

WPS is a compact three-way passive array for small and medium touring systems, theatres, concert halls, worship spaces and corporate AV. Published output is 133 dB peak, or 139 dB peak with crest factor 4. Its low weight and modest footprint also suit side hangs, front fills and delay arrays in larger Wavefront Precision systems.

Integrated three-way acoustic architecture

Four 1-inch-exit neodymium HF compression drivers feed a full-width horn with 100° horizontal constant directivity. Using several smaller drivers reduces distortion and supports upper-frequency extension and line-array summation.

Four 4-inch compression-loaded midrange drivers are slot-loaded into the HF horn walls. This integrates their wavefront with the HF section, maintaining vocal clarity and tonal consistency across the 100° pattern. Compression loading provides the efficiency required from the small enclosure.

Two 8-inch neodymium LF drivers sit behind the HF horn walls. Their small front chambers increase output towards the upper LF range, while horizontally separated LF exits contribute pattern control. The horn/reflex arrangement provides controlled bass output within the compact cabinet. An internal passive network integrates the three sections into one amplifier path.

Portable and installed deployment

The ergonomic three-point rigging system supports approved arrays of up to 16 cabinets. Front and rear rigging points provide alignment and pinning, while side and rear handles support repeatable assembly. WPS can work as a main array or as an auxiliary component in a larger system.

Current cabinet construction, protective paint and metalwork provide the published IP54 specification, corrosion resistance, UV stability and protection against heat, cold and humidity. These provisions support touring and permanent installation within the specified environmental conditions.

Scalable resolution and DISPLAY 3

System resolution is set by the number of enclosures assigned to each independently processed amplifier circuit. More circuits give DISPLAY finer control over audience coverage, frequency response and SPL consistency. Resolution can be chosen for the project budget, increased later by adding amplifiers, or varied between main arrays and auxiliary systems.

DISPLAY 3 combines mechanical angle selection with DSP optimisation against user-defined SPL and frequency-response targets. It models audience and non-audience areas, improves low-frequency control and provides greater flexibility in array length. Martin Audio describes its acoustic model as accurate to within ±1 dB of measured data. Hard Avoid can reduce energy at reflective ceilings, balcony edges or areas beyond the audience by up to 30 dB, subject to the system design.

Amplification, network control and identification

The array forms a complete system with dedicated external iKON Class D amplifiers. VU-NET transfers DISPLAY parameters over Ethernet and provides real-time control and monitoring. Dante supports digital audio distribution over CAT5 cabling, including longer cable routes and integration with other network-audio equipment.

Each amplifier output provides up to 1000 FIR taps at 48 kHz for wide-band optimisation. On current enclosures, an LED addressed through VU-NET identifies the cabinet circuit. This integrated design supports repeatable deployment and compatibility between inventories using the same system platform.
