too far and will almost always give you better depth and soundstage
information. A word of caution, however, if you move the speakers
too far from the front wall you may lose focus.
Yet another problem is a lack of mid bass energy. In order for the
appropriate amount of mid bass energy to be present, the speakers
should be close enough together to achieve proper "coupling" of the
midrange driver and the mid-bass couplers. Coupling is desirable in
the lower frequencies from the mid-bass on down. This simply
means that the left and right drivers "work together" as opposed to
working separately.
If you find there isn't enough deep bass, your first remedy is the
volume control on the woofer amplifier. This has several limitations.
First, turned up too high, you may get some distortion on very low
frequencies or you may overheat the amplifier.
Secondly, you may make the mid bass produced by the top of the
woofer out of proportion with the mid bass produced by the bottom
of the mid-bass coupler. This would tend to sound "boomy" in the
mid bass regions.
Another good rule of thumb is to first set the volume control of the
woofer for proper midbass rather than low bass. The theory is that if
the midbass is correct, then the low bass should be very close to
correct. If the midbass is proper and the low bass is still not right,
here are some other suggestions.
A good balance between proper low bass extension and a deep and
spacious soundstage needs to be established to optimize your
speaker's performance.
In order to achieve what the speaker is capable of we suggest you
focus your efforts on a proper balance of soundstage elements that
includes information beyond the left and
right sides of the speakers,
front to back depth well behind the speaker, excellent focus of
instruments and voices with proper vertical information and mid bass
fill.
A Genesis loudspeaker system correctly set up, can and should
provide a soundstage that is wall to wall and with pinpoint focus, the
speakers disappearing completely on a recording containing such
information.
