Loudspeaker congurationsX8 stage monitor with LFDeployed as a stage monitor with SB15m subwoofers, an X8 system operates with augmented LF resources.The [X8_MO] preset allows for a reference frequency response in stage monitoring applications.The [SB15_100] preset provides the SB15m with an upper frequency limit at 100 Hz for an optimal frequency couplingwith the X8.The X8 and the SB15m enclosures are driven by the LA4X / LA8 / LA12X amplied controllers.X8 stage monitor with SB15mWith SB15m, the X8 system contour is reinforced by 8 dB at 100 Hz and the system bandwidth is extended down to 40Hz.35°Enclosure X8 SB15mPreset [X8_MO] [SB15_100]Frequency range (-10 dB) 40 Hz - 20 kHzEnclosure ratio 1 X8 : 1 SB15mDelay valuesDo not forget to add the pre-alignment and geometric delays depending on the conguration.Pre-alignment delays[X8_MO] + [SB15_100] X8 = 0 ms SB15m = 2.6 ms[xx_MO] presets for the X series use the amplied controller low latency operating mode. When used along withsubwoofers, it is recommended to use the subwoofers in low latency operating mode. To achieve this, createcustom 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 areoperated in normal latency mode. Therefore, an additional delay should be set to the [xx_MO] low latencychannels to align them: 2.66 ms on LA8 or 3.00 ms on LA4X and LA12X.X8 user manual (EN) version 5.0 13
