| 8 - STACKING LCC84/LCC44 ON SUB310 USING THE TOWER RIGGING SYSTEM
CAUTION
Tipping Hazard
The Subwoofer Outriggers can be used to apply
minor adjustments to the leveling of the SUB310
or CSUB610 subwoofer units. DO NOT install
any speaker enclosures atop a subwoofer in any
configuration if the subwoofer can not be properly
leveled in its position.
If the subwoofer cannot be properly leveled using the
Outrigger feet, it is necessary to adjust the surface
supporting the subwoofer (floor, stage deck, riser
etc.) in order to level it before deployment. It is the
responsibility of the installation personnel to verify and
guarantee the safety of the installation.
Figure 152. SUB310 Side-to-side leveling.
•
With all four Subwoofer Outriggers installed, and each of the
four adjustable feet of the Outriggers lowered to touch the floor,
place a spirit level (or digital level) across the top surface of the
subwoofer cabinet, parallel to the front grille of the enclosure.
Be careful to avoid placing it on non-flush elements, such as
the Sub Pole Cup.
•
Read the level, and if the Subwoofer is slightly out of level side-
to-side, adjust the feet of the pair of Outriggers on the side that
is lower.
•
To raise the side that is lower, the Outrigger feet can be lowered
by turning them clockwise (as seen from the top of the cabinet).
It may be necessary to tilt the entire subwoofer slightly to raise
the outrigger feet off of the floor before turning them. Try to
make similar adjustments to each of the pair of feet, returning
the subwoofer to rest on the floor after each adjustment and
checking the level each time. This process may need to be
repeated several times to achieve correct leveling. When this is
achieved, proceed to leveling the unit on the front-to-back axis.
Figure 153. Leveling SUB310 side-to-side –
example.
Important: If any of the Outrigger foot being adjusted reaches its
limit (completely lowered) before the subwoofer can be properly
leveled on any axis, it will be necessary to stop this procedure
and either reposition the subwoofer or – where possible, such as
on an adjustable platform or riser – adjust the level of the surface
where the unit is deployed.
