INSTALLATION
UDA Series are frequency shaded passive column speaker types, meaning that most of the speakers
have been low pass filtered in order to widen the high frequency vertical directivity compared to a
conventional passive column speaker. The low pass filtered speakers are reproducing only low or
low&mid frequencies. This technique implies that, on the other hand, the rest of the speakers are
reproducing the whole frequency range, that is low, mid and high frequencies.
