TXD series
Dispersion
TXD series enclosures are designed to provide relatively wide (70°) horizontal coverage. This
allows the majority of live sound applications to be covered with single enclosures placed
individually to take advantage of this performance feature, for example either side of a stage in a
pub or small club environment as shown below. For best results the loudspeakers should be
either mounted on tripod stands or supported on straight poles on top of TXD series bass
enclosures. In order to optimise the sound coverage, point the loudspeakers inwards slightly, such
that the centre lines intersect at a distance approximately equal to twice the width of the stage.
STAGE
It is possible to array TXD series loudspeakers in order to achieve wider horizontal coverage and
in these applications it is recommended that the cabinets be placed such that the trapezoidal sides
are touching to ensure that the appropriate splay angle is observed. For guidance when designing
a sound system, a 70º horizontal polar pattern equals an angle of 35º either side of the centre line
at which the sound pressure level is 6dB down with respect to centre, (averaged over the whole
frequency range of the loudspeaker). Thus a 40º vertical dispersion gives an angle of 20º above
and below the horizon.
