POSITIONING THE SUBWOOFER
stored settings has been overwritten with your new
settings.
• To avoid accidental over-writing of presets, set the
Preset/Settings switch on the subwoofers back panel
(No. 8 in fig. 2) to the "Protect" position. Adjustments on-
the-fly for all settings are still possible.
To recall a Preset:
• Simply briefly press the desired Preset button A, B, C or D.
• Presets can only be stored or recalled in "Master"
mode.
• Program one preset with the best global settings
for your system and use this as the starting point
to program the other presets. This way you always
have a starting and reference point.
Introduction
Although it is often said that the location of a subwoofer in
a listening room is not critical (as the human ear can not
locate direction at very low frequencies) we recommend
that you choose its position carefully so the subwoofer can
integrate fluently with the other speakers in the system and
interact in the correct way with the acoustical environment.
All of the following should be taken as rule-of-thumb
guidelines; bass response in general is very dependent on
the acoustics of the listening environment. Finding the best
position often involves a lot of trial-and-error experimenting.
Always trust your ears, even if seemingly the position of
the subwoofer goes against the guidelines. Contradictory
as it may seem, good integration of subwoofers has been
achieved when one isn't aware that a subwoofer is present
at all in the system, yet performance involves fast, deep
and solid bass without sounding stressed, even at loud
levels.
• Trying to find the right location will also involve finding
the right settings such as Level, Cross-over frequency
and Phase for that location. The subwoofers presets will
prove to be a useful tool when trying to find a suitable
setting: You can store the settings that match a particular
position so you can easily swap between locations. It will
also allow you to make small changes in settings and to
store these as separate presets. This way, you can
compare between presets to find the best setting. Refer
also to section "Storing and recalling a Preset" in Chapter
"Adjusting and Using the subwoofer".
• When experimenting to find the optimal location, use a
couple of music tracks with repetitive bass across a large
spectrum. The tracks should be sufficiently different from
each other and each should cover a wide bass-range.
Musical instruments, such as a double-bass, bass guitar,
church organ, etc. cover a wide spectrum in the bass
region and are therefore very suitable. Using non-music
(such as action movies) material to position and adjust
the subwoofer with, may lead to spectacular results with
such material but almost always it will result in overblown
and excessive bass when playing music with the same
setting. Remember that the Dynaudio subwoofers allow
for 4 different preset settings, so you can store a preset
with the setting that matches the occasion (be it for
action movie or music listening) best.
Every listening environment will have specific "room-
modes", whereby in some specific locations in the room
and at particular frequencies, the bass may be too much or
too lean. This effect will be stronger in square and "shoe-
box" shaped rooms. With a single subwoofer, the better
position for the subwoofer relative to the listening position
will be the one where bass is perceived to be neither too
much or too lean at any given frequency.
