X12 Stage Monitor With Lf; X12 With Sb15M - L-Acoustics X12 User Manual

Loudspeaker configurations

X12 stage monitor with LF

Deployed as a stage monitor with SB15m or SB18 subwoofers, an X12 system operates with augmented LF resources.
The [X12_MO] preset allows for a reference frequency response in stage monitoring applications.
The [SB15_100] and [SB18_100] presets provide the SB15m and SB18 with an upper frequency limit at 100 Hz for
an optimal frequency coupling with the X12.
The X12, SB15m and SB18 enclosures are driven by the LA4X / LA8 amplified controllers.

X12 with SB15m

With SB15m, the X12 system contour is reinforced by 8 dB at 100 Hz and the system bandwidth is extended down to
40 Hz.
Delay values
Do not forget to add the pre-alignment and geometric delays depending on the configuration.
[xx_MO] presets for the X series use the amplified 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 amplified 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: 2.65 ms on LA4 and LA8 or 3.08 ms on LA4X.
