B
ass drums, organs, and
electronic synthesizers produce
extremely low frequency
sounds. But traditionally, few
home loudspeakers are designed to
reproduce bass below about 50 Hz.
Today, however, home loudspeak-
ers are called upon to reproduce
more than music: in home theater
systems, they are called upon to
reproduce movie soundtracks. And
modern movie soundtracks contain
a lot of energy at very low frequen-
cies—on sound effects. To do full
justice to these effects, as well as to
the musical low frequencies missed
by most speakers, the Cambridge
SoundWorks BassCube subwoofers
reproduce, at high output, the lowest
bass sounds the human ear can
detect.

You should keep in mind
when installing your system and
investigating its capabilities that
you will be dealing with a relatively
unfamiliar range of sounds. These
are sounds more felt than heard,
and are encountered more often in
the well-equipped movie theater
than in the concert hall.
A Cambridge SoundWorks Audio/
Video Consultant is only a toll-free
call away should you need advice or
assistance.

Upon unpacking your BassCube
subwoofer, please examine it
carefully for any signs of shipping
damage. If there is any damage, do
not install or use the subwoofer.
Consult the store where you pur-
chased the subwoofer for assis-
tance. If purchased through our
mail order catalog service, call
Cambridge SoundWorks at
1-877-YES-HIFI.
We suggest that you keep the
shipping carton and packing mate-
rials in case you want to transport
your subwoofer.
Unpacking Audio And AC Power Connections
Be sure the speaker wire con-
nects the positive (+) terminals of
the subwoofer to the positive (+)
terminals of the amplifier or re-
ceiver (and similarly connects the
negative (–) terminals together). All
two-conductor speaker cable is
coded along one conductor by
lettering, a stripe or a raised bead
-or- the appearance of the two
conductors differs, usually one
copper and one silver. This allows
you to easily connect the proper
conductor to each terminal.
Connection Method Three:
Connect from a stereo preamp
output to the BassCube subwoofer’s
Line Level inputs. A suitable length
of conventional stereo phono cable
with RCA plugs at each end is all
you need if your preamp has an
unused stereo preamp output.
To connect between a stereo
preamp and a stereo power amp,
combine a suitable length stereo
phono cable with two “Y” adapters.
Each adapter has one RCA male plug
to two RCA female jacks (Figure 3).
Some receivers and integrated
amplifiers have preamp outputs and
power amp inputs that are accessible
by removing jumpers from the back
panel.
Note: Make all connections with the
BassCube subwoofer switched off
and the Bass Level control at its
minimum setting.
Audio Connections
The BassCube subwoofer can be
connected to a mono subwoofer
output, a main amplifier’s speaker
outputs, or from stereo preamp
outputs.
Note: You should connect the
BassCube subwoofer to your system
using either the line level inputs or
the speaker level inputs–but not
both sets of inputs.
Connection Method One:
Connect from a subwoofer output
using a suitable length mono
phono cable with an RCA phono
plug at each end (Figure 1 on
page 3). Connect the phono cable
to the Right channel line level
input on the BassCube subwoofer.
Connection Method Two:
Connect directly from an amplifier
or receiver’s speaker output termi-
nals to the subwoofer’s Speaker
Level Inputs using conventional
speaker wire. Then connect your
speakers to the Out To Speakers
terminals (Figure 2 on page 3).

A Note About Dolby Digital
(AC-3), Large Front Speakers And
Powered Subwoofers
Most Dolby Digital (AC-3) decoders
remove the Low Frequency Effects
from the Main speakers if the
“Subwoofer Output” switch is set to
“On”. The Main speaker “Large/Small”
switches may still appear to function,
but no deep bass will reach the Main
speakers.
This automatic deep bass filtering is
unnecessary with large Main speakers.
If you wish, you can send all Low
Frequency Effects signals to both your
Main left and right speakers and to
your subwoofer by turning the sub-
woofer output to “Off” and setting the
Main left and right speakers to
“Large”. This blends all the output of
the Low Frequency Effects channel
with the Main left and right speakers.
The BassCube subwoofer needs to be
connected with speaker wire to the
Main speaker outputs in this case.
Power Connections
After making the audio connections,
plug the power cord into any conve-
nient 120-Volt AC, 60 Hz outlet and
switch the subwoofer “On”. Do not
plug it into a switched outlet on your
amplifier or receiver, as either
BassCube subwoofer could draw
sufficient current at high volume
levels to possibly damage the
switched outlet’s relay mechanism.
The BassCube subwoofer has an
automatic “Power Off” circuit that
turns off power to the amplifier
circuit after it has been silent for
over 15 minutes. The BassCube
subwoofer rapidly activates as soon
as a new signal is present. This
feature operates when the switch

2. The BassCube subwoofer can sit in
a variety of positions within the
listening room. Make sure there is a
clear air space of at least 4 inches
surrounding the BassCube
subwoofer’s amplifer panel. Don’t
place objects on the BassCube
subwoofer (such as clothing) that
could inadvertently drape down the
back of the unit, restricting air flow
or speaker output. Similarly, do not
conceal the BassCube subwoofer
behind draperies or other similar
material.
3. The maximum low bass output of
the BassCube subwoofer is mark-
edly affected by adjacent room
surfaces. Start by placing the
subwoofer against the same wall
as your front speakers, preferably
in or close to a corner (Figure 4, B
or C). The strongest output will be
produced with the subwoofer
directly in the corner, since corner
Place the BassCube subwoofer in
your listening room using the
guidelines that follow. Listen and
experiment with placement before
making the installation permanent.
1. The BassCube subwoofer’s very
low bass output is room-filling.
This is why it is possible to use a
single powered subwoofer to
reproduce all the deep bass a
sound system requires. It is also
the reason why the subwoofer
doesn’t need be particularly close
FIGURE 4: HOW ROOM PLACEMENT AFFECTS BASS RESPONSE
labeled “Auto-off Setting” is in the
“Auto” position. Most home users will
find this setting to be appropriate.
The “manual” position of the
“Auto-off Setting” switch keeps the
amplifier operating and drawing a
small current so long as the Power
switch is in the “On” position. This
setting is appropriate when the
BassCube subwoofer is used in
professional sound studios.

placement “directs” most of the bass
output toward the center of the
listening room. Corner placement
effectively reduces the amount of
bass that leaks out to other rooms.
Less bass output will result if the
subwoofer is placed out in the
room, away from the walls (see
Figure 4, A).
4. The larger the room, the greater the
demand for low-frequency acoustic
energy. The best type of room for
bass reproduction in a home theater
would be one moderate in size,
solidly constructed, with no
openings to other rooms.
While listening, shut the room’s
doors and windows (if practical).
It can make a surprising difference.
Note: The BassCube subwoofer’s
are designed to operate sitting
on the floor. Do not place the
sub-woofer in shelving or
other cabinets.

Note for Ensemble owners: The
BassCube subwoofer is intended
to supplement, not replace the
separate subwoofers supplied with
these systems. Do not disconnect
your Ensemble woofers when
using the BassCube subwoofer.

•160 Hz: Use this setting with
small main speakers or if you
are connecting the subwoofer to
the LFE output of a Dolby
Digital system.
Special note about line-level
subwoofer outputs
Many receivers and all Dolby
Digital (AC-3) processors feature
dedicated subwoofer outputs. Some
of these outputs are full-frequency
bandwidth. Others deliver a signal
which is “Bass Only”.
Before you adjust the output level of
the subwoofer, you should select an
appropriate setting for the Low Pass
Frequency control. The proper setting
depends on the bass “reach” of your
main speakers. This control behaves
the same whether you use the
Speaker Level or Line Level signal
inputs of the BassCube subwoofer.
Because there is a small output
level shift when you adjust this
control, it should be set first, followed
by the Subwoofer Level control.
Use the following guidelines to
choose the best setting.
Selecting Low Pass Frequency
Most subwoofer outputs on
conventional receivers (stereo or
Dolby Surround with Pro Logic)
deliver a full frequency range signal,
a mono version of stereo signal fed
to the main speakers. BassCube
owners using this type of subwoofer
output should set the Low Pass
Frequency control as described in
the procedure above.
The second type of subwoofer
output sends a “Bass Only” signal
to the BassCube subwoofer. The
most common example is the Low
Frequency Effects (LFE) channel of a
Dolby Digital (AC-3) equipped
system. Set the Low Pass Frequency
control to 160 (FROM LFE OUT-
PUT) with this type of subwoofer
output. Try a lower frequency
setting only if there is too much
bass output on non-Dolby Digital
(AC-3) program material.
It is possible to improve the
performance of your main speakers
by the use of optional Low Cut
Filters (see page 7).

It may take several listening
sessions using different films and
musical sources to arrive at the
single best setting for the Level
Control. The subwoofer’s Level
Control is intended to be set once
and then left alone.
Once you have decided on a
setting, use tone controls on your
main electronics to compensate for
the inevitable small differences in
bass output between different
recordings. If you experience any
difficulty, don’t hesitate to consult
your store or call a Cambridge
SoundWorks Audio/Video Consult-
ant at 1-877-YES-HIFI.
The Subwoofer Level Control adjusts
how loudly the BassCube subwoofer
plays. Start with it set midway (5),
then adjust upward or downward
depending on what you discover
during your listening tests.
Remember the BassCube
subwoofer reproduces bass that is
below most frequencies of musical
interest, so it is important to adjust
its output level with material that
contains strong, deep bass signals.
It’s easiest to adjust the Subwoofer
Level Control when listening to the
appropriate film soundtracks (HiFi
video cassette, Laser Disc, or DVD’s).
Action or adventure film
soundtracks generally have the
deepest bass signals. Try films with
explosions or similar sound effects.
With the BassCube subwoofer
properly adjusted, these film and
video sound effects should literally
be room-shaking at high playback
levels. In contrast, much of the
music on audio CDs should not
sound any different with the
BassCube subwoofer properly ad-
justed. Indeed, if the subwoofer does
add “boomy” or “thumpy” quality to
your music, you may have the
subwoofer level control set too high.
Our “in the speaker line” Low-
Cut Filters optimize the perfor-
mance your system at higher
output levels by keeping the low
frequencies best left to the
subwoofer out of the smaller
main front speakers. This eases
the burden on the front speakers
and amplifier, letting them play
more cleanly at higher levels, a
major potential benefit of having
a subwoofer in the first place.
• These filters are ideal for use
with Cambridge SoundWorks’
Model Seventeen, and
Ambiance®speakers, and
other conventional systems of
reasonably wide range. Connect
these filters between your main
speakers and your amplifier.
The filters begin to block bass
signals to your main speakers
below about 140 Hz, so that
below 100 Hz, almost no bass
signals reach your main
speakers.

• These optional filters can be
connected at either end of the
speaker wires of your Left and
Right Main speakers.
1) You can connect a filter’s
INPUT FROM AMP wires to
speaker outputs on your
receiver or amplifier, then
reconnect the main speaker wire
to the filter’s OUTPUT TO
SPEAKER leads with the wire
nuts supplied.
2) You can also connect a filter
at the speaker. Connect the
filter’s OUTPUT TO SPEAKER
leads to your speaker’s input
terminals, then reconnect the
main speaker wire to the filter’s
INPUT FROM AMP wires with
the wire nuts supplied.
• As with all speaker connections,
be sure to maintain consistency
with respect to the + and —
terminals on the receiver and
those on the speakers, including
the BassCube subwoofer. The
connecting wires on the filters
are coded by the use of one
copper-colored conductor and
one silver.
