Wavefront Precision

WPM

WPM is a two-way passive ultra-compact line array element
consisting of two 6.5" reflex loaded neodymium magnet low
frequency drive units, and three 1.4" neodymium magnet high
frequency compression drivers loaded by constant directivity
waveguides.
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.

Mechanical Design

WPM is designed mechanically to be an easy to handle, quick to
rig, safe, rugged and stable touring loudspeaker.
The cabinet is constructed predominantly from high grade multi-
laminate birch and poplar plywood, with an integral 3-point rigging
system.

Acoustic Design

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.

In conjunction with automated DISPLAY system design and VU-
NET network control software applications, WPM features scalable
resolution for advanced array control, resulting in outstanding
levels of consistent, high quality audio that can be distributed to
every point throughout the audience in a venue.
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.
Two side pocket handles and two rear grip handles make handling
safe and easy, and the cabinet is finished in black textured paint
with a fabric-backed protective steel grille.
Each LF driver also features a demodulation ring in the neodymium
motor system to minimise 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.
The use of multiple small HF drivers instead of traditional large
diaphragm CD drivers results in less distortion and extended HF
response.
