Positioning
The position of subwoofers in studio
rooms is generally less critical compared
to full-range monitors. However, best
results will most likely be obtained if
your 18S is placed between the left and
right monitors or in the vicinity of one of
them. If this is not practical, a subwoofer
position to the side of the left or right
monitor, or against a side wall can also
provide good results.
Placing a subwoofer close to or behind
or the listening position, even in multi-
channel surround sound installations,
generally results in inferior performance,
especially in terms of stereo imaging.
Moving the subwoofer closer to walls
and corners will generally increase the
amount of bass. Although the extra
amount of bass can be compensated
for by reducing the volume level of
the subwoofer relative to the rest of
the system, this can result in uneven
bass response at the listening position.
Experiment with the position of your
18S to nd one which yields the best
compromise between convenience,
volume and even bass response.
The 18S incorporates signal processing
that can compensate for the time delay
and volume level differences between
the subwoofer and monitors resulting
from their relative positions with respect
to the listening position. Once you have
positioned your subwoofer, measure the
distances as illustrated. The measured
distances should then be specied at the
appropriate locations in the subwoofer
conguration menu. The conguration
menu is described in Section 3 of this
manual.
Installation
Note
Two subwoofers used in a
single installation can improve
performance by maintaining low
frequency stereo separation and
effectively averaging the effects of
low frequency room resonances.
Note
Every studio room will have
“room-modes”, where at specic
locations and frequencies,
the bass may be under or
overemphasised. This effect is
likely to be stronger in square
and rectangular shaped rooms.
Experimenting with the position
of the subwoofer is likely to reap
benets in terms of minimising
room modes.
The 18S signal processing is able
to compensate for a maximum
of 5.35m difference between
subwoofer and monitor distances
to the listening position.
