LF contour
In this configuration the LF contour is reinforced and the bandwidth is extended in the low end. Depending on the
deployment SPL rejection can be produced.
The [K2 70], [K2 90] and [K2 110] presets allow for a reference frequency response in long throw applications. Each
preset is dedicated to a horizontal directivity setting.
The [K1SB_60] preset provides the K1-SB line source with an upper frequency limit at 60 Hz for an optimal frequency
coupling with the K2 line source.
Three deployments are available in this configuration:
K1-SB
on top
of K2
K1-SB
beside
K2: side LF rejection (polarized)
K1-SB
behind
K2: rear LF rejection (cardioid)
The K2 enclosures are driven by the LA4X or LA8
amplified controller.
The K1-SB enclosures are driven by the LA8
amplified controller.
