X8 Point Source With Lf - L-Acoustics X8 Owner's Manual

Loudspeaker congurations

X8 point source with LF

Deployed as a point source with SB15m subwoofers, an X8 system operates with augmented LF resources.
The [X8] preset delivers a reference frequency response in short throw applications.
The [SB15_100] preset provides the SB15m with an upper frequency limit at 100 Hz for an optimal frequency coupling
with X8.
The X8 and SB15m enclosures are driven by the LA4X / LA8 / LA12X amplied controllers.
X8 with SB15m
With SB15m, the X8 system contour is reinforced by 8 dB at 100 Hz and the bandwidth is extended down to 40 Hz.
Frequency range (-10 dB) 40 Hz - 20 kHz
Enclosure ratio 1 X8 : 1 SB15m
Grouping subwoofers
Place the subwoofer enclosures side by side. If not possible, the maximum distance between two adjacent
acoustic centers must be 1.7 m if the upper frequency limit of the subwoofer system is at 100 Hz.
Use [xxxx_xx_C] or [xxxx_xx_Cx] on a reversed subwoofer in a cardioid conguration
The cardioid conguration consists in reversing 1 element in an array of 4 subwoofers.
Refer to the subwoofer owner's manual and to the Cardioid congurations technical bulletin.
Delay values
Do not forget to add the pre-alignment and geometric delays depending on the conguration.
