WPM System
USER GUIDE
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. 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.
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. 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.
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. 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.
