L-Acoustics K1-SB Manuel D'utilisation page 15

2 - When combining [K1] with [K1SB_60], the K1 is associated with the K1-SB in a CONTOUR configuration.
The CONTOUR configuration consists in installing a K1-SB line array besides or behind a K1 line source array (see
Figure 6) so as to reinforce the system sub-low frequency response. In addition, the acoustic pattern generated by
the system features a LF rejection on the K1 side (polarized) or the rear side (cardioid), respectively.
The K1-SB:K1 recommended ratio is 1:2 and the combined system low frequency limit is 30 Hz.
