System Setup When Using a Subwoofer
Some older surround sound decoders and receivers offer a choice of “Nor-
mal” or “Wide-band” modes for the center channel speaker. The FS-4000
speaker is designed to be used in the Normal mode.
Modern digital processing multi-channel systems provide a Bass Man-
agement menu, which typically requires you to select between “Small” or
“Large” speakers during system set-up. When using this speaker with a
dedicated subwoofer, please set all the speakers on the receiver’s set-up
menu to Small.
Many of the newer surround receivers and processors give you a choice
of subwoofer-to-satellite crossover frequency. If yours does, we recom-
mend that you start with a setting of around 80Hz for the smoothest blend
between the subwoofer and the FS-4000.

System Setup Without a Subwoofer
For some listeners, a full home theater setup with a separate subwoofer and
rear surround speakers may not be feasible or desired. In that case, the FS-
4000 will provide high quality sound all by itself—far better than the small
speakers built into most televisions. In those situations, we recommend you
set your surround sound receiver’s set-up menu to “Subwoofer—No,” and
“Surround Speakers—Off.” Set this way, most receivers will blend some
of the rear channel surround information into the front channels, giving a
more spacious sound.

ADVANCED USER SETUP: For even better results, if your surround
receiver has an adjustable subwoofer crossover frequency, select
“Subwoofer—Yes” (even though you are not using a subwoofer) and
adjust the subwoofer lowpass control to 60Hz. That way, all the bass
from 60Hz and above will be sent to the FS-4000, which will result in
a full-bodied, credibly full-range sound to be reproduced by the FS-
4000, while at the same time, preventing the very low bass signals
(below 60Hz) from overdriving the receiver’s amplifi er section at high
output levels.

Boundary Compensation
Putting this switch to
the “On” position adjusts the lower frequency out-
put to compensate for the typical sound colorations
caused by placing the speaker very close to a large
surface, such as a TV screen, a wall, or on a shelf in an
enclosed entertainment unit. If your FS-4000 speaker
is mounted as described above, you may prefer its
put to compensate for the typical sound colorations
caused by placing the speaker very close to a large
surface, such as a TV screen, a wall, or on a shelf in an
enclosed entertainment unit. If your FS-4000 speaker
is mounted as described above, you may prefer its
sound when the Boundary Compensation controls are engaged. Conversely,
if it is free-standing, away from large surfaces (such as when the speaker
is placed on a stand shelf, away from other large surfaces), you may prefer
the sound with the position in the “Normal” position.
In all cases, we recommend you try both switches in their various positions
and use the settings that sound best in your particular room. Note that the
settings of the Left, Center, and Right speakers may differ from each other.
