Basis 300
Typically the Basis 300 will produce the smoothest
response when placed against a wall. Placement in a
corner can enhance audible bass output. This may allow-
ing you to run operate the subwoofer at a lower power
level. However in some case corner placement will result
in "thick" or "heavy" sounding bass. Experiment with
subwoofer placement while at the same time adjusting
crossover frequency, output level, and phase. (See sec-
tion on Fine-Tuning The Subwoofer.)
Ic-Basis 300
The IC-Basis 300 is engineered for the boundaries and
conditions found in cabinets and millwork. In addition it
can be configured so the driver is either front or down
firing. If the subwoofer is installed in a location where
the front of the cabinet is fully open to the listening
room, then the front firing configuration may be used.
If the subwoofer is installed in a location where the
front of the cabinet and driver are not fully open to the
listening room, then reconfiguring the subwoofer for
downward firing will probably produce better perfor-
mance.
Reconfiguring the IC-Basis 300
•
Carefully lay the subwoofer in its right or left side
on a surface that will not damage the cabinet.
•
Remove the feet from the and the cover plate from
the bottom of the cabinet. Disconnect the wires
from the amplifier to the subwoofer and volume
control. (Simply push in on the back of the speaker
terminals and pull out the wire and disconnect the
plug-in connector of the volume control wires.)
•
Remove screws around the periphery of the ampli-
fier, leaving the screws in the upper corners for last.
Then, while holding the amplifier in place, remove
the last two screws and the amplifier.
•
Locate the five pilot holes around the driver.
Reinstall the four feet previously removed and the
additional foot shipped with the unit.
•
Carefully roll the cabinet onto what will now be
the front surface, that is, the one with the volume
control. Be sure the gasket around the amplifier in-
stallation hole is set properly, then set the amplifier
in place.
•
Carefully reinstall the mounting screws. Replace the
screws in the corners first, driving them in just until
they are lightly set. Then reinstall the remaining
screws in the same way. Then, working from side-
to-side and corner-to-corner, gradually tighten the
screws until they are all firmly set. Be sure not to
over-tighten the screws.
•
Carefully roll the cabinet onto its feet. Reconnect
the volume control. Connect the wires to the driver
– be sure the red and black wires are attached to
the respective red and black speaker terminals.
•
Be sure the gasket around the cover plate installa-
tion hole is set properly, then set the plate in place.
Carefully reinstall the mounting screws using the
same procedure described for the amplifier mount-
ing screws.
