A15i Wide/Focus line source element
A single A15i Wide/Focus can be used as a line source element. In this conguration, the system operates over the
nominal bandwidth of the enclosure.
The [A15_FI] preset delivers a reference frequency response in short throw applications.
The A15i Wide/Focus enclosures are driven by the LA2Xi / LA4X / LA8 / LA12X amplied controllers.

A15i 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
KS21i with an upper frequency limit at 60 Hz.
The A15i Wide/Focus and KS21i enclosures are driven by the LA2Xi / LA4X / LA8 / LA12X amplied controllers.

Use [xxxx_xx_C] or [xxxx_xx_Cx] on a reversed subwoofer in a cardioid conguration
The cardioid conguration consists in reversing 1 element in an array of 4 subwoofers.
Refer to the subwoofer owner's manual and to the Cardioid congurations technical bulletin.
Grouping subwoofers
Place the subwoofer enclosures side by side. If not possible, the maximum distance between two adjacent
acoustic centers must be 2.8m or 1.7m if the upper frequency limit of the subwoofer system is at 60Hz or
100Hz, respectively.
