The configuration “Sat+Sub”, composed of
two systems
XTQ12
and
XTSQ15
,
XTQ15
and
XTSQ18
allows to obtain an extended
and complete frequency response, enriched
at lower frequencies.
Fig. 8 Configuration “Sat+Sub”
Stacking on floor are usually made positions
loudspeakers one up one. In this case there
are “coupling effect” on middle-high frequency
band and increase vertical directivity and
enable a perfect angular coverage. Quality
and limited dimensional in comparison with
loudspeakers power make Modular Line
loudspeakers specially recommended for
difficult acoustic environment.
Safety instructions.
It is important that loudspeaker systems are
used in a safe manner. Professional
loudspeakers are capable of producing
extremely high sound levels and should be
used with care. Hearing loss is cumulative
and can result from levels above 90 dB, if
people are exposed for a long period. Never
stand close to loudspeakers driven at high
level. In case of ground stacking, ensure that
the floor or stage is level and solid. Do not
ground stack speakers too high, in outdoor
applications, where wind could topple the
stack. Flying systems should only be
assembled from trained and experienced
crew, working in association with professional
riggers.
Stacked or flown.
Although flown systems are generally
preferred by most sound engineers, there are
good arguments to support both solutions. In
many cases the answer is dictated by logistic
constraints that are venue-specific, i.e.,
sometimes it isn’t simply possible to fly PA.
Stacking on stage lowers the perceived sound
image to stage level, which is beneficial in
small venues. Stacking also offers more low
frequency SPL due to enhanced floor
coupling. Flying system
is the best solution to
achieve uniform sound pressure level and
even tonal balance over the entire audience,
provided that the number of elements arrayed
is sufficient to provide the necessary
coverage.
