Line source with low-frequency element
In this configuration – where a KIVA line source is used with SB15m subwoofers and optional SB18 subwoofers – the
bandwidth
of the KIVA system is extended in the low-end and the LF contour
is reinforced.
The [KIVA] preset allows for a reference frequency response in medium to long throw applications.
The [SB15_100] preset provides a 100 Hz upper frequency limit for the SB15m.
The [KIVA_SB15] preset combines the [KIVA] and [SB15_100] presets to facilitate the use of this configuration.
The [SB18_60] preset provides a 60 Hz upper frequency limit for the SB18.
This configuration is driven by the LA4, LA4X or LA8 amplified controller. When using the [KIVA_SB15] hybrid preset,
additional SB18 subwoofers must be driven by another amplified controller.

Delay settings
When combining a line source with subwoofers, delays may have to be added to the presets.
Refer to the
PRESET GUIDE
to obtain the pre-alignment delay values.
The [KIVA_SB15] hybrid preset does not allow the independent definition of parameters (gain, delay, etc.) for
different output channels.
When different parameters need to be defined for different channels, it is necessary to build a custom preset
with the [KIVA] and [SB15_100] presets. Refer to the
LA NETWORK MANAGER

instructions
