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 (not included, sold separately).
WARNING!: When deploying loudspeakers on subwoofers, additional attention should be given to account for
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 (not included) when necessary.
LA108 Loudspeaker
An array of up to four (4) LA108 loudspeakers can be stacked over:
a. One (1) LS118/KS118 subwoofer when the subwoofer is upright, or
b. Two (2) LS118/KS212C subwoofers when rotated on their side.
NOTE: For this ground-stack deployment, the LA108-AF (Array Frame)
and the LA108-KIT-SA (Stack Adapter Kit) accessories are needed (not
