Loudspeaker congurations
K1-SB
The K1-SB provides an extension of the bandwidth in the low end, down to 30 Hz. Depending on the deployment, LF
rejection can be produced.
Three deployments are available in this conguration:
• K1-SB on top of the K2 line source
• K1-SB beside the K2 or K2/K1-SB line source : side LF rejection (polarized)
• K1-SB behind the K2 or K2/K1-SB line source : rear LF rejection (cardioid)
