One could do this, and it was how things were

are seeking to do is to create phantom images
between pairs of speakers, and for this you
need a mixing style. "[A]djusting the balance"
is called pair-wise mixing and, unfortunately,
this doesn't work with surround sound.

You can hear this for yourself by performing
the very simple experiment described on my
website at:

Pair-wise mixing is also discussed in the
Ambisonic Surround Sound FAQ at:

If you use an appropriate mixing style, such as
Ambisonics, then you don't need more than
four speakers (although more is helpful).
