Practice Safe Lifting
The following procedure describes how to assemble a groundstack with two
MS218 subwoofers.
1. Prior to stacking, ensure that the lower subwoofer is mounted on a at,
dry, and solid horizontal surface, capable of safely bearing the weight of
the assembly.
2. With the help of assistants, carefully lift the second MS218 subwoofer on top
of the lower subwoofer. Make sure that the feet of the top subwoofer t into
the corresponding recesses on top of the lower subwoofer.
Take care not to trap your ngers between components.
3. The MS218 subwoofers can also be installed rear-facing. A front-mounted
input on each MS218 can be used to make the speaker wiring connections
easier and neater.
4. The MS218 subwoofer groundstack must be carefully and securely tied down
to prevent tipping.
! WARNING
DO NOT EXCEED A TOTAL QUANTITY OF 3 MS218 SUBWOOFERS FOR THIS
GROUNDSTACK CONFIGURATION. FAILURE TO FOLLOW INSTRUCTIONS MAY CAUSE
PERMANENT INJURY OR DEATH.
! WARNING
WHERE POSSIBLE ALWAYS SECURE THE GROUNDSTACKED SPEAKERS TO THE
STACKING SURFACE WITH ADDITIONAL FIXINGS SUCH AS RATCHET STRAPS.
