Loudspeaker configurations
Line source with low-frequency element
A L2/L2D line source can be deployed with additional subwoofer enclosures to extend the bandwidth in the low-end or
increase sub-low resources.
The [L2 xxxxx] / [L2D xxxxx] presets deliver a reference frequency response in long throw applications with horizontal
directivity settings and cardioid or supercardioid LF polar pattern. Refer to Line source (p.51).
The [KS28 L2xxx] presets provide an optimal frequency coupling of the subwoofers with the L2/L2D line source in
separated or coupled configuration.
KS28 can be driven by LA2Xi / LA12X amplified controllers.
Reduced maximum SPL or drive capacity with LA2Xi: refer to the LA2Xi owner's manual.
L2/L2D line source with coupled KS28
Two deployments are available in this configuration:
• KS28 behind the L2/L2D line source (recommended)
• KS28 beside the L2/L2D line source
1 m to 2 m
3.3 ft to 6.6 ft
0.5 m to 1 m
1.6 ft to 3.3 ft
with KS28 behind with KS28 beside

Frequency range (-10 dB) 25 Hz - 20 kHz
Use [xxxx_xx_C] or [xxxx_xx_Cx] on a reversed subwoofer in a cardioid configuration
The cardioid configuration consists in reversing 1 element in an array of 4 subwoofers.
Refer to the subwoofer owner's manual and to the Cardioid configurations technical bulletin.
Delay values
Do not forget to add the pre-alignment and geometric delays depending on the configuration.
Refer to Pre-alignment delays (p.54).
