Loudspeaker congurations
A15 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 [A15_FI] preset delivers a reference frequency response in short throw applications. The [KS21_60] preset provides
KS21 with an upper frequency limit at 60 Hz.
The A15 Wide/Focus and KS21 enclosures are driven by the LA4X / LA8 / LA12X amplied controllers.

Grouping subwoofers
Place the subwoofer enclosures side by side. If not possible, the maximum distance between two adjacent
acoustic centers must be 2.8 m or 1.7 m if the upper frequency limit of the subwoofer system is at 60 Hz or
100 Hz, respectively.
Delay values
Do not forget to add the pre-alignment and geometric delays depending on the conguration.
pre-alignment delays
[A15] or [A15_FI] + [KS21_60]
A15 Wide/Focus = 0 ms
KS21 = 2.6 ms
[A15] or [A15_FI] + [KS21_60_C]
