Page 7: K2 Horizontal Directivity Settings
3 K2 HORIZONTAL DIRECTIVITY SETTINGS The K2 enclosure features an adjustable horizontal directivity system. Using the adjustable fins, horizontal directivity can be adjusted with four different settings: 110° and 70° symmetric or 90° asymmetric, i.e., 35° 55° or 35° + 55°. A specific K2 preset must be used for each directivity setting. -
Page 8: Loudspeaker Configurations
enclosure ® user manual VERSION 1.0 4 LOUDSPEAKER CONFIGURATIONS Line source Deployed as a standalone line source, a K2 system operates over the nominal bandwidth of the K2 enclosure, with an adjustable horizontal directivity. The [K2 70], [K2 90] and [K2 110] presets allow for a reference frequency response in long throw applications. Each preset is dedicated to a horizontal directivity setting. -
Page 9: Line Source With Low-Frequency Element
Line source with low-frequency element Deployed as a line source with coupled K1-SB subwoofers, a K2 system operates with augmented LF resources. Two configurations are available: LF throw: for enhanced LF projection. LF contour: for reinforced LF contour. 4.2.1 LF throw In this configuration the LF throw capability is... -
