Loudspeaker congurations
Line source with low-frequency element
A K3i 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 K3i 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.
*
KS21i/KS28 cannot be mechanically coupled with a K3i line source in an array. The KS21i/KS28 and K3i arrays
must be own or stacked independently. Refer to the
KS21i/KS28 owner's manuals
for more information on
how to set up a KS21i/KS28 array.
