Figure 9. Subwoofer Placement
NOTES: • To produce a good bass response from the subwoofer, it should be located at
the front of the room, somewhere between either corner and a point about
one third of the way along the front wall.
• The output channel used for the Left Back speaker (in 7.1 configurations) is
also used for the Center Back speaker (in 6.1 configurations).
Bass Management
Low frequency sound is usually better handled by the subwoofer. Bass management creates
the subwoofer channel by separating the low frequency information from the satellite
speakers at a user-defined crossover point. This is summed with the Low Frequency Effects
(LFE) information encoded in the source format. When no subwoofer is present, subwoofer
content is sent to speakers set to Large (excluding the center speaker).
Speaker Size Settings
This feature sets bass management on or off for a particular speaker, defining the frequency
range output by that speaker. These settings also enable or disable the subwoofer and set
the crossover frequency.
z Left and right front speakers and left and right surround speakers are set in pairs.
z The center speaker is set as an individual speaker.
z Back speaker(s) can be set as a single speaker or as a pair of speakers, depending on the
system configuration.
Small — Bass management is on for that speaker. The output to each speaker (other than
the subwoofer) is limited to frequencies above the crossover frequency. By default, center
and surround speakers are set to Small.
