7. Arrayed Speaker (Cluster)
If the loudspeaker are operated through K&F system controller, we recommend to use the
'Top Low Cut' switch for this operation. So you can optimize the frequency response for this
application.
When operating the systems without any K&F system controller, you should decrease the
frequencies below 300 Hz for 3-4 dB.
