Why a line source speaker?
Better directivity helps to reach better speech intelligibility in reverberant spaces and reduces noise pollution in open spaces. The traditional way to increase the directivity of a column speaker at lower frequencies is to increase its length.
What are the advantages of the cardioid pattern?
- less off-axis horizontal radiation in low frequencies
- tighter vertical beam in low frequencies compared to the same length of a conventional line
- source speaker
- higher STI values can be achieved in high reverberation environment
- less noise pollution in opne spaces
