13.0 - Splay Angles – Above 10 degree
It should be noted that the angles 10-15 degrees have been made accessible in order to
allow 'breaking' of the system. This is used in situations such as balcony coverage in
theatres. In order to avoid reflections from balcony fronts (especially in relatively short
throw applications) it can be helpful to employ large array angles to keep some of the
energy off the balcony front before resuming coverage. Essentially above around 10
degrees splay – a 'gap' in coverage will start to become far more noticeable – the higher
angles have been included for just this reason – allowing greater flexibility should one
need to 'break' the array. It is appreciated that whilst it is not acoustically ideal to break
the array in some ways (slight loss of coupling for example) we at EM acoustics believe
the benefits of being able to approach otherwise challenging venues makes the addition
of this feature worthwhile.
