WPM is a 2-way passive, 2 x 6.5” mini line array featuring scalable resolution optimisation. This flexible approach to array optimisation provides greatly improved coverage, consistency and control compared to a standard line array.

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

WPM is incredibly versatile. Its very small footprint and light weight make it the system of choice for smaller venues which require superb fidelity, coverage consistency and control from an ultra-compact line array. With a peak SPL of 130dB peak, it is also very powerful — a 12-box array will throw beyond 35 metres (115ft) and produce live music at high levels in up to 3000-seat venues. It embodies the very latest acoustic technology in an ultra-compact enclosure and is the ideal system for small-to-medium scale theatres and live music venues, AV events and installations in concert halls, ballrooms and HoW.

A passive 2-way system with an impedance of 16 ohms, it can be driven in blocks of 1, 2, 3 or 4 resolution configuration. With a complement of 2 x 6.5” (165mm) LF drivers and a vertical column of 3 x 1.4” (35mm) aluminium dome HF drivers, the acoustic design of WPM is uniquely innovative. The LF drivers are located in the side walls of the HF horn — an arrangement which would introduce acoustic cavities which would degrade the horizontal dispersion if conventional cone drivers were used. WPM’s drivers adopt an elegant solution by having solid moulded diaphragms which match the contours of the horn walls and maintain the continuity of the horn profile. Each LF driver also features a demodulation ring in the neodymium motor system to minimize distortion and maximise mid-band output.

In the triple-driver HF section, each individual HF wavefront is precisely coupled to the horn throat via a short waveguide for faultless 100° horizontal constant directivity coverage.

Architectural Specs
Wavefront Precision WPM

The loudspeaker shall be a vertically-arrayable, two-way passive system powered by a dedicated controller amplifier. Its transducers shall consist of two 6.5” low frequency drivers and three 1.4” dome high frequency drivers coupled to a constant directivity horn.

The loudspeaker shall have 100° horizontal dispersion and 10° vertical dispersion. Vertical dispersion of the complete array shall be determined by a combination of the splay angles between adjacent enclosures and dedicated array control software. The on-axis frequency response shall be 76Hz-18kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 130dB peak at 1 metre. Power handling shall be 300W AES, 1200W peak. Rated impedance shall be 16 ohms.

The rear of the enclosure connector panel shall be fitted with two NL4 type connectors.

The loudspeaker enclosure shall be constructed from multi-laminate birch and poplar ply and finished with a durable textured black paint. The drivers shall be protected by a perforated steel grille with a scrim cloth backing and the enclosure shall incorporate a pocket handle in each side panel and two rear grip handles. The enclosure shall additionally incorporate an integral three-point rigging system to assemble an array of up to 16 enclosures suspended from a dedicated flying frame.

Dimensions (W x H x D) shall be 500mm x 185mm x 377mm (19.7in x 7.3in x 14.8in). Weight shall be 14kg (26.4lbs).

The loudspeaker shall be the Martin Audio Wavefront Precision WPM.
