About speaker sizes (LARGE and SMALL)
Internally, the LARGE and SMALL settings for each speaker
determine whether or not the internal sound processor will cut
the bass signal from that channel. When the bass is cut from a
channel the bass redirection circuitry sends the corresponding
bass frequencies to the sub woofer or other "LARGE" speaker.
However, since bass sounds have a certain amount of
directionality it best not to cut them, if possible. Therefore, even
when using small speakers, you can set them to "LARGE" if you
want to output the bass frequencies from that speaker. On the
other hand, if you are using a large speaker, but prefer not to
have bass frequencies output from that speaker, set it to
"SMALL".
If the overall sound level is lower than you prefer, set all speakers
to "LARGE". If there is not enough bass, you can use BASS +/–
to boost the bass levels. To adjust the bass, see page 32.
