Ground Deployment
Stacking over a Subwoofer(s)
LA108/LA112 active line array loudspeakers offer the ability to safely stack an array over an
LS118/KS118 subwoofer(s) unit using the appropriate Array Frame and Sub Stack Adapter
Kit (sold separately).
WARNING!:
When deploying loudspeakers on subwoofers, attention should be
given to environmental conditions such as level surfaces, vibrations, wind, etc. to
deploy the loudspeakers in a stable and safe manner. Use additional measures to
secure the subwoofer (hardware not included with subwoofer) when necessary.
LA108
An array of up to four (4) LA108 loudspeakers can be stacked over one (1) LS118/KS118
subwoofer when the subwoofer is upright, or two (2) LS118/KS212C subwoofers when
rotated on their side.
LA112
An array of up to three (3) LA112 loudspeakers can be stacked over one (1) or two (2) LS118/KS212C when the subwoofers are
rotated on their side.
NOTE:
For these ground-stack deployments, the LA108-AF (Array Frame) and the LA108-KIT-SA (Stack Adapter Kit) accessories
(sold separately), or the LA112-AF (Array Frame) and the LA112-KIT-SA (Stack Adapter Kit) accessories (sold separately) are
needed on the top (LS118/KS118/KS212C) or side (LS118/KS212C) of the subwoofer to secure the array. These combined
accessories bolt onto the M20 thread located on the top or side of the subwoofer (LS118/KS212C) to secure the array. See next
section for proper deployment of these two accessories, please refer to the individual accessories' user manuals.
