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 amplied controller.
