Loudspeaker congurations
5XT stage monitor with low-frequency element
Deployed as a stage monitor with SB15m or SB10i subwoofers, a 5XT system operates with augmented LF resources.
The [5XT_MO] preset delivers a reference frequency response in stage monitoring applications.
The [SB15_100] and [SB10_100] presets provide SB15m and SB10i with an upper frequency limit at 100 Hz for an
optimal frequency coupling with 5XT.
5XT, SB15m, and SB10i are driven by the LA2Xi / LA4X / LA8 / LA12X amplied controllers.
5XT stage monitor with SB15m
With SB15m, the 5XT system contour is reinforced by 16 dB at 60 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 conguration.

[5XT_MO] + [SB15_100] 5XT = 0.2 ms SB15m = 0 ms
[ xx _MO] presets for the X series and A 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 LA4 and LA8 or 3.00 ms on LA2Xi, LA4X, and LA12X.
