Speakers Size Sub-Menu
The bass management settings 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 instead of those low
frequencies re-directed to a subwoofer. 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. We recommend finding out what the lower limit is for each of your
speakers, as it is useful for several settings in this sub-menu.
Each set of speakers (Front, Front Height, Center, Surround, and Surround Back) can
be set to “Large” or “Small”, and all of the speakers except for the Fronts can be set to
“None.” Surround Back speakers can only be set to “Large” if the Surround speakers
are also “Large”. The subwoofer can be set to “Yes” or “No”, but “No” is only an option if
the Front speakers are set to “Large”.
Because the SR5004 supports either a single surround back speaker or a pair of
surround back speakers, the “Surround Back” setting can be “None” (no surround back
speakers), “1ch” (a single surround back speaker), “2ch” (a stereo pair of surround back
speakers), or “Zone SPKR” (if the surround back speaker terminals are being used to
power speakers in Zone A).
When any speakers are set to “Small”, the SR5004 will apply bass management to
those speakers and redirect low frequencies to either the subwoofer or “large” front
speakers. The crossover point used by this bass management can be adjusted to
coordinate with the speakers in your system. This adjustment is the “LPF/HPF”
