2 - When combining [KARA] with [SB18_60] the KARA is associated with the SB18 in decoupled configurations.
The SB18:KARA recommended ratio is 2:3.
Note1: Two SB18 array arrangements are possible whether the directivity pattern is intended to be omni-directional
or cardioid. The cardioid arrangement is recommended within arrays containing a multiple of four SB18 enclosures and
in that case the [SB18_60] preset must be replaced by [SB18_60_C] (see Figure 10 and refer to the SB18 User
manual [3.4]).
Note2: A small KARA array (typically composed of 6 enclosures as shown in Figure 10) of standard curvature provides
a flat contour. If needed, the KARA contour can be reinforced in the low frequency domain using the LF CONTOUR
tool of LA NETWORK MANAGER Software [3.4] with frequency set at 180 Hz and gain set between 0 and 4 dB.
The association of KARA and LF CONTOUR allows reaching some unprecedented results when KARA are flown and
SB18 are stacked due to the extended bandwidth and low-end capabilities of KARA.

3 - When combining [KARA] with [SB28_100] the KARA is
associated with the SB28 in coupled configurations only. The
SB28:KARA recommended ratio is 1:3.
Note: This configuration is possible but not optimized. Due to the
lower sensitivity and additional LF extension of SB28 versus SB18, it
requires a SB28:KARA ratio of 1:3 (two times more 18" drivers are
needed).
