2. Unpacking your DB1 Subwoofer
The DB1 is heavy and we strongly suggest that it is
unpacked close to its final working position by two
people working together.
The table above illustrates the component parts that
are packed with the subwoofer. In the unlikely event
that anything is missing please in the first instance
contact the retailer from whom you purchased the
subwoofer.
Remove the protective film from the front of the display.

The DB1 may be used free-standing on the floor or be
installed into custom built furniture.
The positioning of a subwoofer is generally less critical
than for full-range speakers. Furthermore, the DB1 is
also more versatile than most subwoofers in terms of
positioning thanks to its on-board equalisation and
optimisation system that can compensate to some
extent for less than ideal positioning. Section 6.4
describes use of the equalisation system.
Best results, however, will be obtained if the DB1 is
placed between the left and right speakers or in the
vicinity of one of them. Placing a subwoofer to the side,
but still to the front of the listeners is an acceptable
compromise if domestic considerations dictate, but we
recommend you avoid placing the subwoofer behind
the listeners. If two DB1 subwoofers are to be used it
is best to position one near the left speaker and one
near the right speaker. The diagram above illustrates
subwoofer positioning.
Note: Using two subwoofers in a single installation
can improve performance by maintaining stereo
separation to the lowest frequencies, averaging
the effects of low frequency room resonances and
enabling a higher maximum volume level. In the case
of two subwoofers used in a 2-channel audio system,
stereo separation will only be improved if each
channel has its own subwoofer located close to the
appropriate satellite speaker.
Note: Like all speakers, the proximity of room
boundaries affects the sound of a subwoofer. Bass
volume increases as more surfaces come into close
proximity. The more boost gained from the room, the
lower the volume can be set and the less hard the
subwoofer has to work.
Note: The orientation of the DB1 connection and
control panels with respect to its drive units may be
changed if desired by turning the amplifier module
by 90°. When shipped, the subwoofer's drive unit
panels are oriented at 90° to the connection and
control panels. There may be situations, however,
when the connection and control panels are best
oriented to be on the same plane as the drive units;
the subwoofer installed in custom made furniture
that provides little side clearance for example.
To change the orientation, first carefully turn the
subwoofer on to its top, making sure when turned
that it rests on a surface that will not damage its
finish. To release the amplifier module use a 15mm
spanner to unscrew the four foot location posts.
Once the posts are unscrewed the amplifier module
may be turned through 90°. It does not matter which
way it is turned but if it is returned to its previous
position it should be turned back the way it came.
With the amplifier module in its new position the foot
posts can be replaced and tightened.
