•
100 Hz
: This position is
appropriate to high-quality
systems with less low-bass
reach, such as those
designed to achieve higher
efficiency at the expense of
low bass.
•
140 Hz
: This position can be
used with small speakers for
creating your own satellite-
type system. 140 Hz is the
highest frequency recom-
mended for this purpose; the
ear tends to localize sounds
that are higher in frequency.
See page 8 for advice on
how to set the overall subwoofer
level.
If more than dusting is
needed, the vinyl finish of the
Powered Subwoofer II
can be
cleaned with a window or vinyl
cleaning product. Avoid
spraying the cleaner directly on
the speaker grilles to prevent
damage to the speaker.

The
Powered Subwoofer II
has a four position “low-pass”
switch. One of the four settings
of this switch will enable the
Powered Subwoofer II
to best
“take over” the very low bass
seamlessly from your existing
speakers. The following
guidelines will help you choose
the appropriate setting for your
system. Alternatively, you may
choose to set the switch by ear.
•
55 Hz, 80 Hz
: Use one of
these two positions with
Cambridge SoundWorks’
Ensemble
®
or
Ensemble II
, or
with any other wide range
speaker system. Typically,
this would be a large
acoustic suspension
bookshelf speaker, where
bass reach has not been
sacrificed for efficiency.
Which switch position to
choose will be affected by
where the main speakers
and subwoofer(s) are placed
in your listening room. The
closer your main speakers
are to the corners of the
room, the more likely the
55Hz setting will be the
better choice. See the
“Placement” section which
follows for more information.
Note
: The
Powered
Subwoofer II
is intended to
supplement, not replace, the
separate woofers supplied
with Ensemble systems.
Do not disconnect your
Ensemble woofers when
using
Powered Subwoofer II.
