and the level is set to be close to the sensitivity of
the satellite speakers, so no adjustment should be

Select a piece of music that you are familiar with which
has a constant repetitive bass line. Start with the level
and frequency controls in the middle positions and the
phase control set to zero. Adjust the level control until
you are happy with the low frequency levels compared
to the main speakers. Now adjust the frequency control
so that there is no obvious change in the sound from
very low frequencies to higher frequencies. Adjust the
phase control to achieve the smoothest integration
between sub and main speakers. KEF recommends
that you take some time adjusting the controls, whilst
listening to a varied selection of music, until you are
satisfied with the sound balance.
With large full-range speakers
