will almost always give you better depth and soundstage information.
A word of caution though: if you move the speakers too far from the
front wall you may lose the focus of the image.
4.4 Appropriate Mid-bass Balance
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 ribbon drivers at the lower frequencies. Coupling between
the left and right channels 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 independently.
With the broad wings of the Genesis 1.2, we have not found this to be a
problem. However, if the tweeter-to-tweeter distance is more than 10
feet, or the gap between the two wings is more than 7 feet, you will find
that the speakers lose coupling, and the mid-bass suffers.
4.5 Optimizing Deep Bass
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.
If you like a lot of bass, it is possible to push the bass gain up, but in
that case, it would be wise to also raise the high-pass crossover from
16Hz to 26Hz or even beyond to 30Hz in order to protect the woofers
and to keep the bass amplifier from overheating.
Another solution is to push the woofer towers back towards the front
wall or even closer to a corner. This will increase the coupling of the
woofers to the room. Do this procedure in small increments
(approximately one inch at a time), and return often to the recordings
you have used to adjust the front to back depth and soundstage
properties of your system. It is easy, yet unproductive, to go too far in
one direction. If you move the woofer towers too far from the front wall
you may lose low bass extension, too near and you may get too much
wall reinforcement.
A problem that you could create is that you may make the mid-bass
produced by the top range of the woofer out of proportion with the
mid-bass produced by the bottom range of the midrange ribbon. This
would tend to sound slow or thick in the mid-bass regions. When you
raise the bass gain, you will want to reduce the low-pass crossover to
90Hz or further.
