INTRODUCTION:
The TWIN-X is capable of delivering high SPL’s in even the most demanding applications and exhibits true
constant directivity, providing an even frequency response over the entire area of coverage.
The TWIN-X full range cabinet comprises one sophisticated low frequency (LF) driver and high frequency (HF)
sources are exactly aligned to a point source, resulting in a smooth uniform frequency response over a wide area
of coverage either as a portable stand alone system or in a multi-cabinet array. As the system is a point source,
clusters and arrays have minimal lobing. These features are inherent and achieved without the use of any
electronic signal processing.
The asymmetric cabinet profile allows flexible and discreet installation. As a foreground system, installation is
made simple with any type of mounting hardware or the system can be flown using the integral M10 inserts.
For portable stage use the birch ply cabinet has a recessed carrying handle on the rear of the cabinet. As a
versatile low profile stage monitor, the conical coverage pattern gives the performer greater freedom of movement.
Equalisation:
The TWIN-X loudspeaker is designed to need no equalisation or correction to overcome system limitations. As a
result, it will only need equalisation to compensate for difficult acoustic environments.
Over equalisation can reduce system headroom, and introduce phase distortion resulting in greater problems than
cures. If equalisation is required then it should be applied gently and smoothly. The TWIN-X loudspeaker is a
point source, phase coherent design and violent equalisation will be detrimental to the overall sound quality.
When a loudspeaker is used in close proximity to another, comb filtering effects can create coverage problems,
comb filtering creates an uneven frequency response across the coverage area due to constructive and
destructive interference effects between the sources. The amount of comb filtering is affected by the spacing fo
the relative sound sources. Minimising this effect cannot be cured by equalisation.
