right for the singer, everybody else in the band. The mystery was
solved when we looked at a picture of the recording session, and
noticed that the singer was looking down towards her notes, and the
microphone was hung over her head. It was no wonder that when the
system is correctly adjusted, it sounded like the singer was standing in
a pit in relation to the rest of the instruments in the band.
If you have the speakers only 20% away from the front wall, and you
are not getting enough front to back depth (the background behind the
singer not appearing behind the speaker enough), pull the midrange
tweeter panels 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. If you get the speakers much beyond 1/3 of the
way into the room (or 27 ft), it is unlikely that pulling them further
away will have any further effect.
Find the best compromise for your room, your tastes and your space
requirements. If the speakers are too far apart you will lose the side
image and if they are too close together you will have too small a
center stage. We recommend you begin with the midrange/tweeter
wings six to eight feet apart as measured from tweeter to tweeter. If
you are not getting proper focus on the voice, you may angle the
midrange panels about 5 to 10 degrees towards your seating position
until you have a properly defined center image.
When properly set up, very little sound should appear to come
directly from the speaker. Instead, the sound stage should extend far
beyond the left and right edge of the loudspeakers and there should
be tremendous front to back depth. When the recording is close-miked
(when the instrument or performer is very close to the recording
microphone), the music may appear to come directly from the
loudspeaker. This is normal. Typically, however, the sound should
appear to be detached from the loudspeakers.
A simple rule of thumb to follow is that focus will be achieved by
placing the speakers closer together or toed-in. Front to back depth
can be adjusted by varying the distance from the rear wall. Further, as
the system “breaks-in”, the depth and width of the soundstage will
increase, and so will the “smoothness” of the sound.
3.3 Phase Control
We suggested in the beginning of this section to set the bass phase to
0 degrees. Now that you have roughed the system in, you may want
to experiment with different phase settings.
