Additional subwoofer system
All the configurations described in the previous sections can be deployed with additional K1-SB or SB28 subwoofer
enclosures to provide increased sub-low resources to demanding applications.
SB28 enclosures are ground-stacked. K1-SB enclosures are flown on the side or behind the system.
The available configurations are described below, along with the recommended ratios corresponding to each K2
configuration.
The [SB28_60] and [K1SB_60] presets provide the SB28 and K1-SB enclosures with an upper frequency limit at 60 Hz,
for an optimal frequency coupling with any of the configuration.
The SB28 and K1-SB enclosures are driven by the LA8
amplified controller.
