The WT2 is a powerful, compact theatre system which can be used as a stand-alone enclosure in a distributed  
system or arrayed in multiples. The switchable active/passive two-way cabinet is very efficient, combining  
smooth dynamic full-frequency performance with excellent articulation, utilising high power drive units for  
maximum SPL.  
Optimum performance is achieved with the MX5 or DX1 controller configured for the WT2 to perform  
system specific equalisation, phase adjustment, crossover and limiter functions. With a Wavefront Series sub-  
bass system, ultra-low frequency enhancement takes the power bandwidth to below 35Hz.

technical specifications  
architectural and engineering specifications  
TYPE  
Compact two-way trapezoid, switchable  
active/passive  
The loudspeaker system shall be of the two-way  
switchable active/passive type consisting of one 12"  
(300mm) direct radiating reflex loaded low frequency  
transducer and one 1" (25mm) exit HF compression  
driver mounted on a constant directivity horn in a  
trapezoidal plywood enclosure. The enclosure shall be  
fitted with an integral pole mounting socket and  
threaded inserts to facilitate a variety of mounting  
options. Active or passive operation shall be selected by  
a switch at the rear of the enclosure. In active mode the  
loudspeaker shall be bi-amped and operated with a  
separate electronic controller. In passive mode, low and  
high frequency sections shall be integrated by an  
internal 2kHz passive crossover network.
