4. Fine Tuning
HTM61 S2
Before fine tuning, make sure that all the connections in the
installation are correct and secure.
Moving the speakers further from the walls will generally
reduce the volume of bass. Space behind the speakers will
also help to create an aural impression of depth. Conversely,
moving the speakers closer to the walls will increase the
volume of bass. 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 (above).
If the bass seems uneven with frequency this will most
probably be due to resonance modes in the listening room.
Even small changes in the position of the speakers or the
listening position can have a profound effect on how these
resonances affect the sound. Try moving the listening position
or locating the speakers along a different wall. The presence
and position of large pieces of furniture can also influence
resonance modes.

If the sound is too bright, increasing the amount of soft
furnishing in the room (heavier curtains for example) may help
balance the sound. Conversely, reducing the amount of soft
furnishing may help brighten a dull sound.
Ensure that the speaker stands firmly on its support. If a floor
stand is used to support the speaker, use carpet piercing spikes if
appropriate and adjust them to take up any unevenness.
