Loudspeaker congurations
X12 with KS21
With KS21, the X12 system contour is reinforced by 6 dB at 60 Hz and 2 dB at 100 Hz, and the system bandwidth is
extended down to 31 Hz.
Values and ratios are the same for KS21i.

Delay values
Do not forget to add the pre-alignment and geometric delays depending on the conguration.

[X12_MO] + [KS21_100] X12 = 0 ms KS21 = 0.4 ms
[xx_MO] presets for the X series use the amplied controller low latency operating mode. When used along with
subwoofers, it is recommended to use the subwoofers in low latency operating mode. To achieve this, create
custom presets combining low latency channel sets and subwoofer channel sets.
If the subwoofers are driven from a dedicated amplied controller using a subwoofer factory preset, they are
operated in normal latency mode. Therefore, an additional delay should be set to the [xx_MO] low latency
channels to align them: 2.66 ms on LA8 or 3.00 ms on LA4X and LA12X.
