Line Source With Low-Frequency Element - L-Acoustics K Series Owner's Manual

Loudspeaker congurations

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
conguration 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 2.8 m or 1.7 m if the upper frequency limit of the subwoofer system is at 60 Hz or
100 Hz, respectively.
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.
*
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.
