Loudspeaker congurations
Line source with low-frequency element
A K3 line source can be deployed with additional subwoofer enclosures to extend the bandwidth in the low-end or
increase sub-low resources.
The [K3 70], [K3 90], and [K3 110] presets allow for a reference frequency response in long throw applications. Each
preset is dedicated to a horizontal directivity setting.
The [xxxx_60] presets provides the subwoofers with an upper frequency limit at 60 Hz in separated or coupled
conguration for an optimal frequency coupling with the K3 line source.

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.
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.
*
KS21 cannot be mechanically coupled with a K3 line source in an array. The KS21 and K3 arrays must be own
independently. Refer to the KS21 owner's manual for more information on how to set up a KS21array.
