NOTE: LARGE VS SMALL SPEAKER SETTINGS:
It is very important that you understand what is meant by the LARGE and SMALL settings in this menu. They
do not refer to SIZE, but to the ability of the particular loudspeaker system to handle low bass/low frequency
information. It is very important that you consult your loudspeaker providers instruction manual or the company
regarding the capabilities of your particular system with regard to low bass/low frequency reproduction. Please
note that all THX certified loudspeaker systems are SMALL since a subwoofer is a part of any THX certified
loudspeaker system. It is strongly recommended that you consider using a subwoofer for any system which you
expect to effectively handle the low frequency dynamics of modern motion picture soundtrack sources such as
DVD or HDTV feeds, and many other discrete multi-channel programming sources. If in any doubt choose
small, especially if you are using a subwoofer, since this will insure that all the appropriate low frequency
information is directed to the subwoofer where it can be most effectively handled.
