L-Acoustics A10 - With Low-Frequency Element

Loudspeaker congurations
A10 Wide/Focus line source element with low-frequency element
With a complementary subwoofer, the system is extended in the low end and the LF contour is reinforced.
The [A10_FI] preset delivers a reference frequency response in short throw applications. The [KS21_100] preset provides
KS21 with an upper frequency limit at 100 Hz.
The A10 Wide/Focus and KS21 enclosures are driven by the LA4X / LA8 / LA12X amplied controllers.

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