CHAPTER 5
Bass Management
The
The advantages of redirecting the bass to a subwoofer are :
•The overall bass of the system is improved as subwoofers, such as Sunfire's powered
True Subwoofers, are specially designed for this frequency range.
•The subwoofer can simulta- neously play the bass from all of the speakers, in addition to its own low frequency effects channel (LFE).
•There is no loss in percep- tion of the position of movie or music sound effects, as the ear cannot easily locate the posi- tion of bass sound sources.
•Smaller speakers can be used for front, center and sur- rounds, as they do not have to reproduce the low frequency range. This leads to a saving in speaker expense and room space. Note that a subwoofer is required if the front speakers are not set to LARGE.
•The
The SPEAKER SIZE menu is used to set the bass management correctly for your speaker system.

The speaker choices are:
OFF: The speakers are not present.
LARGE: the speakers receive the full frequency range, and their bass is not redirected to the subwoofer.
40, 45, 50...150 Hz: The bass below this frequency is redirected to the subwoofer. Check your speaker manuals to find their frequency re- sponse, and choose a frequency that is above the lowest, or choose 90 Hz as a good starting point.
NOTE: Dolby Digital and DTS modes are designed especially for complete systems with front, cen- ter, and surround speakers and subwoofers. You need all of the speakers to get the best performance from your Home Theater. If you do not have a subwoofer connected and you are using large speakers, then you should not use the bass management system (so set all the speakers to Large). Without a subwoofer, you will be missing the 5.1 LFE (low frequency effects) information.
Considering the advantages of the bass management system, you might try setting all of your speakers to 90 Hz (for example), even if they are capable of good
