Sidewalls. Because the speaker is a dipole it is less sensitive
to the sidewalls. However, as a rule of thumb, it is a good idea
to keep the speaker as far away from the sidewalls as is
practical. With this in mind, it may be helpful to add some
damping material or diffuser panels to the point of first
reflection.
This is where the sound from the loudspeaker first hits the
sidewall, then bounces to the listener. This reflection is
undesirable because it is slightly delayed from the original
sound. The point on the sidewall can be easily determined with
the help of a second person and a mirror:
Sitting in your listening position, have an assistant hold a mirror
up on the sidewall. Move the mirror until you can see the
tweeters. This is the point of first reflection. A diffuser (see your
dealer), an absorptive material or even a piece of furniture can
help break up this point of first reflection. The best diffuser is
also the most useful, a full-height rack of LPs!

Rear wall. In many cases it will be unnecessary to do anything
with the wall behind your listening position. However, if due to
the constraint of room size you are sitting very close to the rear
wall, you may want to experiment with diffusers or absorbers
behind you for best sound. Some absorption behind the
listener is usually beneficial in reducing slap echos.
3.6 Mastering the Refinements of the system
Fine tuning an audio system is an art that will take time and patience.
It can be one of the more rewarding learning experiences you will
have in the pursuit of music and its enjoyment. Unfortunately, for the
G1.1, trying to move the loudspeakers yourself is also likely to give you a
hernia. Luckily, the dipole line-source is easily positioned, and your fine
tuning may be confined to the settings on the servo-bass amplifier.
One of the best pieces of advice we can offer is that you take
advantage of the ear's ability to identify similarities in sound. This
ability is useful in fine-tuning your system because, if every recording
you listen to has a similarity of sound (too much or too little of a certain
frequency for instance), then you can be fairly certain that you have yet
to perfect your set-up. Keep at it and remember to enjoy your music
as you work on perfecting your set-up.
