10 CSB Corner Subwoofer

80Hz should be employed if you are using larger speakers that have
extended bass response. This way, the subwoofer will only reproduce the
very lowest bass frequencies that are in the range where the large main
speakers begin to roll off.
It’s generally undesirable to have the main speakers and the subwoofer
overlap too much. Larger speakers means a lower Low-pass crossover
frequency, smaller speakers means a higher Low-pass crossover fre-
quency. Consult the manufacturer’s speciﬁed low frequency response
for your main speakers to determine the appropriate Low-pass setting
on your subwoofer. In the end, however, a little time spent experimenting
will generally result in dramatically better bass response.

The Phase Control

A subwoofer operating out of phase with
the rest of the system won’t provide opti-
mum low frequency performance. Also, the
subwoofer's phase can be affected by room
acoustics. Since there is variation in the
industry regarding phase, a control that will

adjust the phase of the subwoofer is provided on the ampliﬁer panel.
Listen to a monaural musical source with strong bass content. (For
example, you can use the mono switch on an FM tuner or preamp, or
use a Y-connector on the outputs of one of your source components to
get a mono signal.)
Experiment with the position of the phase control to get the smooth-
est bass. Careful listening will reveal the correct setting. In particular,
there will be a more integrated transition between the satellites and the
subwoofer when they are properly phased.

A Word About Bass, Center Channel Modes

and System Set Up

Many surround processors and receivers feature a “Wide” and “Normal”
mode for the center channel speaker. Atlantic Technology recommends
that the center channel be operated in the “Normal” mode when using
a powered subwoofer. The center channel speaker will sound more
dynamic and the intelligibility of the system will generally be improved
when in the “Normal” mode.
With discrete digital 5.1, 6.1, or 7.1 channel systems (Dolby Digital, DTS,
etc.) many controllers provide a Bass Management option, which lets you
set the front and rear speakers in a limited bandwidth (Small) or full
range (Large) mode. When using a subwoofer with Atlantic Technology
speakers we recommend setting such a controller to the Small position
for all the speakers in the system, with one exception.
When using the high level input connected to your receiver/ampliﬁ-
er's left and right speaker outputs, set the "speaker size" for these left
and right channels to "large." This will deliver full-range signals to the
subwoofer. The left and right speakers are then connected to the sub's
high level outputs, which have ﬁltering to remove deep bass and therefore
avoid overdriving these speakers.

Care of Your Subwoofer

The 10 CSB is constructed from Medium Density Fiberboard. MDF is a
non-resonant material ideal for speaker system enclosures. To clean the
cabinet you may use a soft cloth either dry or slightly dampened with
clean water. Be careful not to wet the cabinet or allow any water to enter
the cabinet seams. Avoid placing your speakers in direct sunlight or near
a source of heat that may, over time, damage the ﬁnish.

IMPORTANT:

Save Your Boxes! If you can do so, save the carton,

packing pieces and plastic bags that came with your subwoofer.
They will be useful in case you move or have to ship your
subwoofer for any reason. In any case, save all packing materials
until you are certain that the system has suffered no damage in
shipment. If you ﬁnd such damage, either visible or internal, con-
tact your dealer immediately for the proper return procedure.
