4. Fine Tuning
Before fine tuning, double check that all the
connections in the installation are correct and secure.
Moving the speakers further from the walls will
reduce the general level of bass. Space behind the
speakers also helps to create an impression of depth.
Conversely, moving the speakers closer to the walls will
increase the level of bass and potentially reduce the
impression of depth.
If you want to reduce the volume of bass without
moving the speakers further from the wall, fit the foam
plugs or, for less severe bass reduction, the foam rings
in the port tubes. Fitting a foam plug or ring in a port
tube is illustrated above.

If the bass is uneven with frequency, it is usually due to
the excitation of resonance modes in the room. Even
small changes in the position of the speakers or the
listeners can have a profound effect on how these
resonances affect the sound. Try positioning the
speakers along a different wall. Even moving large
items of furniture can have an effect.
If the sound is too harsh, increase the amount of
soft furnishing in the room (for example, use heavier
curtains), or reduce it if the sound is dull and lifeless.
Test for flutter echoes by clapping your hands and
listening for rapid repetitions. Reduce flutter echoes
by the use of irregular shaped surfaces such as
bookshelves and large pieces of furniture.
5. Assembly and cable routing
After you have settled on the positioning of the
speakers, switch off the electronic equipment and
disconnect the cable from the speakers. Take the
speakers off the stands and place them on the floor.
Turn each stand upside down to fit four feet. If the floor
is carpeted, use the spike feet to pierce through the
carpet and provide a firm foundation. For non-carpeted
floors, use the alternative domed rubber feet. In both
cases, screw a lock nut fully down the threaded stem
of each foot and then screw the foot fully into the
threaded sockets in the base of the stand.
