In the Quick Setup Guide, we skipped past most of the
Manual Setup
menu because we
used the Audyssey MultEQ XT automatic setup.
Speaker Setup Sub-Menu
Amp Assign was discussed in the Quick Setup section on page 22. The other entries in
this menu are all set by the Audyssey Automatic Setup (if it is used) but can be
manually adjusted if desired. Before we move any farther, however, we should pause to
review bass management briefly because a number of the settings in this sub-menu
relate to bass management.
The
bass management
settings under “Speaker Config.” and “Crossover Frequency”
will determine how low frequency audio is managed between the speakers. “
Large
”
defines a speaker as being capable of reproducing low frequencies. “
Small
” defines a
speaker as one that should have low frequencies re-directed to a subwoofer. It is the
“small” speakers that receive bass management. Which setting is appropriate should
not be determined solely by a speaker’s physical size. Instead, it should be determined
by the speaker’s performance characteristics. Speaker manufacturers provide a number
of specifications with each speaker, and the frequency response specification is the
best way to determine if a speaker should be considered “large” or “small.” This
specification may be listed as a range (such as “54Hz-21,000Hz +/-3dB”), or as a value
for the lower limit (such as “Low Frequency Extension: 54Hz (-3dB)”). Some people will
classify speakers as “large” if the low frequency limit is as high as 40Hz, and some
people will require speakers to achieve close to 20Hz to be considered “large”. In
general, a speaker should be considered to be “small” unless the
low frequency limit
is near or below 30Hz. Even for speakers that can play to such low frequencies, a
subwoofer will often provide better performance below 80Hz (louder and/or with less
