Additional Subwoofer System; K1-Sb - L-Acoustics K2/SB28 User Manual

Additional subwoofer system

A K2 line source or a K2/K1-SB line source can be deployed with additional subwoofer enclosures to provide increased
sub-low resources to demanding applications.
Two subwoofer systems are available:
— K1-SB for increased LF contour
— SB28 for infra extension
The recommended ratio is 3 K2 for 2 subwoofers, whether using K1-SB subwoofers only, SB28 subwoofers only, or a
combination of both.
The [K1SB_60] and [SB28_60] presets provide the subwoofers with an upper frequency limit at 60 Hz for an optimal
frequency coupling with the line source.
The K1-SB and SB28 subwoofer enclosures are driven by the LA8 amplified controller.

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 configuration:
— 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)
