IVS line source speaker

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


Directivities: omnidirectional, cardioid, hypercardioid Standard lengths: 1m, 1.5m, 2m, 3m, 4m, 6m, or special size are also available upon request Standard finish: anodized aluminium, bronze or alu colours or special colours are also available upon request Power: 300 W/m MAX SPL (depends on speaker used): 1m length: 98dB/10m - 6m length: 98dB/40m
