The Wavefront Theatre WTUB enclosure has been specifically designed for under-balcony use in theatres and
infill in venues requiring extremely wide horizontal coverage. The WTUB loudspeaker provides sound
reinforcement for speech and music with exceptionally consistent tonal balance over the whole of its coverage
angle. It also shares the same tonal characteristics as the larger members of the WT range, the WT2 and 3.
The unusual driver complement and geometry is responsible for the uniform coverage of the enclosure. A triple
soft dome, high frequency line array coupled with a proprietary diffusion phase plug gives very wide horizontal
and tight vertical dispersion. Its narrow width allows minimal separation between the two 6.5" (165mm) cone
drivers. This factor and the drivers’ 60˚ splay are responsible for the seamless horizontal coverage of the
WTUB. The two 6.5" (165mm) drivers feature 1.5" (38mm) voice coils and an innovative heat exchange system
to reduce power compression. A combination of ferrofluid and a rear mounted heatsink cools the high frequency
line array’s neodymium magnet assembly, with extreme high frequency overload being dealt with by an auto-
resetting over-current device.
Featuring fully passive operation and requiring no controller, the WTUB is extremely straightforward to deploy.
The enclosure input configuration is externally switchable between pins 1 and 2 on the fitted Neutrik NL4MP
connectors. This allows daisy-chaining of cabinets via a 4 core cable, even when they are fed with different input
signals.
The rugged, multi-laminate birch ply enclosure features M8 inserts for the dedicated mounting bracket and an
additional M8 ‘safety chain’ point. The multi-angled cabinet rear allows close proximity ceiling mounting with a
downward tilt of up to 45˚. A pole mount socket gives the additional option of tripod stand mounting.
