Distributing the bass is also helpful for reproduction of multi-channel
music because you get incredible articulation and detail in the bass
all around the room.
The Refinement stage
After following the rough 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.
One rule of thumb you should always keep in mind. Make one
change at a time! Do not, for instance, change position of the
speakers and make an adjustment to the tweeter, midrange, and
bass all at once. Make each of these changes separately and note
the difference - by listening - with each adjustment, then make the
next change.
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 wide soundstage between the two speakers, and creates
problems beyond the unnatural width of the center stage. The key
problem is a lack of soundstage information beyond the left and right
sides of the speakers, and also a loss of focus between the
speakers.
If you find that the sound is not spacious enough or you are not
getting enough front to back depth, pull the speaker away from the
front wall. This is typically preferable to separating the two speakers
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.
