WPC System
USER GUIDE
The WPC is a new breed of medium-format optimised line array which brings innovative acoustic design, ultra-high performance
and coverage consistency to a wider range of users, applications and budgets than previously possible. A three-way, bi-amp
system, it features horn-loaded low-frequency, mid and HF sections to raise efficiency and increase output. Its high efficiency
acoustic design can equal or outperform larger, direct radiator systems — a 12-box array will throw beyond 60 metres (200ft)
and deliver impressive rock levels to a 5,000-seat venue, saving on truck space and weight.
Mechanical Design
WPC 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 WPC's low frequency section consists of 2 x 10" (250mm) neodymium drivers in a Hybrid® configuration which marries the
benefits of horn and reflex loading. Each driver is slot-loaded into a short horn to give a high sensitivity of 103dB @ 1m/2.83V,
while the rear of the driver is reflex-loaded to extend the LF output. The punch and low-frequency extension produced from such
a small enclosure volume are remarkable.
Mid and HF horns are physically separate — a key factor in the WPC's exemplary 100° horizontal constant directivity dispersion
pattern. The midrange horn design utilises 2 x 5" (125mm) neodymium drivers to produce a high SPL of 109dB @ 1m/2.83V,
while the HF section employs 4 x 0.7" (19mm) exit neodymium compression drivers which feed four individual horns. Use of
multiple small HF drivers instead of a more traditionally-used large format compression driver results in less distortion and a
more extended HF response.
