In rooms with solid concrete or brick walls and floors like in Asia and
Europe which have very little bass loss, you may need to turn this down
to 76Hz in order to reduce bass boominess.
Next, set the woofers using more than just a voice. Select some music
that you know to have good deep bass. Set the gain on the woofers for
a natural and powerful bass sound. Use a symphonic piece of music if
you can, or use a natural bass instrument for your guide. Try to make it
sound real. You may have to return to the vocal to make sure you have
not gone too far in one direction.
At this point, if there is not enough mid bass, turn the L
OW
P
ASS
control
to a higher frequency or, alternately, position the main speakers closer
together in order to achieve better mid bass coupling between the main
speakers. If it sounds too “fat” turn the L
OW
P
ASS
control down or adjust
the B
ASS
G
AIN
. At this point it is suggested to use the L
OW
P
ASS
filter
control until you get to the refinement stage.
3.3 Imaging and Soundstage
If your vocal selection is a well-recorded audiophile CD or LP with
good image information in the recording, the performer should appear
to come from behind the loudspeakers and be at the appropriate height
for a standing person. If it is not, there are several remedies that will
address this shortfall.
If the vocal appears to be larger than life, you should first check the
system volume. Is it a volume that would be appropriate for
someone actually singing in your room? If there is too much volume
the artist will appear too big and the opposite is truefor too little volume.
If the volume is set correctly and the image is still too big, place the
speakers closer together and re-listen. Place the speakers no less
than 5 feet apart. If the image is still too big, toe the speakers in a
slight amount.
Conversely, if the image is too small, move the speakers apart. The
speakers should be no more than eight feet apart. Repeat this process
until you have it right. If the voice is too low in height, turn the
M
IDRANGE
control up (turning the knob clockwise) and the image of the
voice will move upward slightly.
If you have the speakers 18 inches into the room, and you are not
getting enough front to back depth (the singer not appearing behind the
speaker enough) pull the speakers away from the front wall a little bit at
a time. If you do not have them pulled far enough away, you may
not have enough front to back depth. However, slightly more than
