W440A
active, processor controlled, bi-amped speaker system

Introduction

When used as the main system for music performances,
theatre, conferences, public address, or as a stage monitor,
W440A proves itself to be an exceptionally accurate, highly
versatile system, providing a rich and broad range of sound
experiences. The low weight to performance ratio makes it
the ideal choice for touring systems, and makes its use in
fixed installations easier. The shape of this one piece cabinet
made from high density polyethylene includes 6 fly points
(patented) which ensure flexible, rapid and safe assembling
in fixed and mobile installations.
The shape of the cabinet allows for both vertical (for standard
P.A.) and horizontal (for stage monitoring) installation.
