Speaker loads
Note that these speaker load
values are given under the as-
sumption that the
AV receiver filters out any
potentially damaging bass
content before transmitting the
audio signals to the
satellite speakers.
Setting up the AV receiver/amplifier
To take full advantage of your System 5 THX
Select2 with the S 5000 SW active subwoofer, use
the “Speaker Setup” utility of your AV receiver
to set the satellites to “small” or “normal” (not
“large”). This ensures that the speakers will re-
ceive the proper amount of signal and that the
volumes of the subwoofers and front speakers will
be matched.
Set the subwoofer to “On” using the “Speaker
Setup” utility (bass management and/or speaker
management) of your receiver. Set the crossover
frequency for the System 5 THX Select2 to 80 Hz.
100 Hz is another possible setting.
Setting up the subwoofer
Many current AV receivers are able to automati-
cally set the correct phase and level for the sub-
woofer using the “Speaker Setup” utility by en-
tering the distance between the subwoofers and
the listening spot. For this to work correctly, the
phase switch of the subwoofer must be set to
“0°” and the volume to “THX”.
If you are using an older AV receiver or another
type of amplifier that does not allow you to set
the subwoofer distance:
You can use the phase switch of the subwoof-
er to manually adjust the phase to the other
speakers. The goal here is to ensure that all
speaker membranes move in the same direc-
tion in the vicinity of the crossover frequency.
If the phase is not set correctly, this can lead to
reduced bass response or even cancellation of
bass frequencies. If the subwoofer is positioned
between the two front speakers, we recommend
setting the phase to “0°”. If the subwoofer is po-
sitioned closer to the listening spot, a phase of
“180°” may be more appropriate. If the subwoof-
er is placed elsewhere, the “180°” setting can be
used to compensate for reduced bass response.
Always set the phase control to the position
where the bass response is strongest.
Compared to the home theatre settings, the
volume setting of the subwoofer may need to
be readjusted accordingly for playing different
types of music. Whereas an action-packed DVD
typically contains massive amounts of sub-bass,
much music content may not. This will be espe-
cially noticeable if you calibrate your system for
optimum DVD playback. To find the best compro-
mise between differing sound sources, use your
own subjective judgement.
