4 The Refinement stage
After following the setup guide above, you may not be completely
satisfied with the results. We share with you here some of our
observations in setting up these loudspeakers.
4.1 Running-in the System
We often make the mistake of setting up a “cold” system, and then are
disappointed when the system breaks in. For all Genesis
loudspeakers, we recommend the use of the IsoTek Full System
Enhancement and Rejuvenation Disc. This will reduce the hundreds
of hours of run-in time needed to a couple of days.
You may find the need to make further adjustments at the 500 hour,
2,000 hour, and 5,000 hour marks. The G1.2 is already run in for at
least 100 hours before delivery, and it should sound pretty good
straight out of its crates.
4.2 Make One Change at a Time
One rule of thumb you should always keep in mind - make one
change at a time! Do not, for instance, change the position of the
speakers and make an adjustment to the amplifier all at once. Make
each of these changes separately and note the difference - by
listening - with each adjustment, then make the next change.
Making any changes to your system may also entail a need for setting
up the system again. Many changes, even something as innocuous
as changing your equipment rack, can change the phase
characteristics and frequency response of your system.
4.3 Defining the Soundstage
A common problem we find with many set-ups is a tendency to
separate the speakers too far from each other. This gives an
unnaturally stretched soundstage between the two speakers, and
creates problems with focus. The key problem is a lack of soundstage
information beyond the left and right sides of the speakers.
If you find that the sound is not spacious enough or you are not getting
enough front to back depth, your first recourse is the rear tweeter
control. Depending on the material covering the walls behind the
G1.2, turning the rear tweeters up or down may improve
spaciousness and depth without too much glare or sizzle.
The next thing to try is to pull the speaker away from the front wall.
This is typically preferable to separating the two speakers too far, and
