suBwooFer rear-PaneL ConTroLs and ConneCTions
Auto-On switch:
• On/Auto: When this switch is set in the “On/Auto” position the
subwoofer will automatically turn itself on when it receives an audio
signal, and will enter the Standby mode when it has gone without
receiving an audio signal for 10 minutes.
• Off: Set the switch in the “Off” position to turn the subwoofer off.
Select this position if you will not be using the subwoofer for an
extended period of time, such as when on vacation.
Phase switch: This switch determines whether the subwoofer driver’s
piston-like action moves in and out in phase with the satellite speakers. If
the subwoofer were to play out of phase with the satellite speakers, the
sound waves from the satellites could partially cancel out the sound waves
from the subwoofer, reducing bass performance and sonic impact. This
phenomenon depends in part on the placement of all the speakers relative
to each other in the room.
Line-Level Input connector: If your receiver/processor has a dedicated
subwoofer output, use a single RCA audio cable (not supplied) to connect
it to the subwoofer’s Line-Level Input connector.
Crossover Frequency control: This control determines the highest
frequency at which the subwoofer reproduces sounds. The higher you set
the Crossover control, the higher in frequency the subwoofer will oper-
ate and the more its bass will “overlap” that of the satellite speakers. This
adjustment helps achieve a smooth transition of bass frequencies between
the subwoofer and the satellites for a variety of different rooms and sub-
woofer locations.
Volume control: Use this control to adjust the subwoofer’s volume. Turn
the knob clockwise to increase the volume; turn the knob counterclock-
wise to decrease the volume.
Speaker-Level Input connectors: If your receiver does not have a
dedicated subwoofer output, use speaker wire (not supplied) to connect
its Front Left and Front Right speaker outputs to the subwoofer’s Speaker-
Level Input connectors. Connect your system’s Front Left and Front Right
speakers to the subwoofer’s Speaker-Level Output connectors (see below).
Speakers and amplifiers have corresponding positive and negative (“+” and
“–”) connectors. The SP150 Speaker-Level Input connectors are marked
“+” and “–” beneath the connector levels. Additionally, the “+” connectors
have red markings, while the “–” connectors have black markings.
To ensure proper polarity, connect each “+” connector on the back of your
receiver or amplifier to the respective “+” (red) connector on each speaker.
Connect the “–” connectors in a similar way. Do not reverse polarities (i.e.,
“+” to “–” or “–” to “+”) when making connections. Doing so will cause
poor stereo imaging and diminished bass performance.
IMPORTANT: Make sure the “+” and “–” wires or connectors do not
touch each other or the other terminal. Touching wires can cause
a short circuit that can damage the subwoofer or your receiver/
amplifier.
Speaker-Level Output connectors: If you used the subwoofer’s Speak-
er-Level Input connectors to connect it to your receiver, you must connect
your system’s Front Left and Front Right speakers to the subwoofer’s
Speaker-Level output connectors. To ensure proper polarity, connect each
“+” connector on the subwoofer to the respective “+” (red) connector on
each speaker. Connect the “–” connectors in a similar way. Do not reverse
polarities (i.e., “+” to “–” or “–” to “+”) when making connections. Doing so
will cause poor stereo imaging and diminished bass performance.
IMPORTANT: Make sure the “+” and “–” wires or connectors do not
touch each other or the other terminal. Touching wires can cause
a short circuit that can damage the subwoofer or your receiver/
amplifier.
AC Fuse holder: The SP150 is factory-equipped with a 2A/250V AC fuse.
If the fuse ever blows:
1. Unplug the subwoofer’s power cord from the wall.
2. Use a screwdriver to remove the blown fuse.
3. Replace the fuse with an identical 2A/250V fuse.
CAUTION: FOR CONTINUED PROTECTION AGAINST FIRE,
REPLACE THE FUSE ONLY WITH THE SAME TYPE AND RATING.
Power cord: After you have made and verified all subwoofer and speaker
connections described in this manual, plug the power cord into an ac-
tive, unswitched electrical outlet for proper operation of the subwoofer.
DO NOT plug this cord into the accessory outlets found on some audio
components.

PLaCing The suBwooFer
ConneCTing The suBwooFer
The performance of a subwoofer is directly related to its placement in the listening room
and its physical position relative to the other speakers in the system.
While it is true that in general our ears do not hear directional sounds at the low
frequencies where subwoofers operate, when installing a subwoofer within the limited
confines of a room, the reflections, standing waves and absorptions generated within
the room will strongly influence the performance of any subwoofer system. As a result,
the specific location of the subwoofer in the room does become important to the
amount and quality of bass that is produced.
For example, placing the subwoofer next to a wall generally will increase the amount of
bass in the room; placing it in a corner (1) generally will maximize amount of bass in the
room. However, corner placement can also increase the destructive effect of standing
waves on bass performance. This effect can vary depending on the listening position
– some listening positions may yield very good results while others may have far too
much (or too little) bass at certain frequencies.
In many rooms, placing the subwoofer along the same plane as the left and right speak-
ers (2) can produce the best integration between the sound of the subwoofer and that
of the left and right speakers. In some rooms, the best performance could even result
from placing the subwoofer behind the listening position (3).
We strongly recommend that you experiment with placement before choosing a final
location for your subwoofer. One way you can determine the best location for the sub-
woofer is by temporarily placing it in the listening position and playing music with strong
bass content. Move around to various locations in the room while the system is playing
(putting your ears where the subwoofer would be placed), and listen until you find the
location where the bass performance is best. Place the subwoofer in that location.

TURNING THE SUBWOOFER ON AND OFF
· If you want the subwoofer to automatically turn on when it receives
an audio signal and automatically turn off after not receiving an audio
signal for 10 minutes, set the Auto-On switch in the “Auto” position.
· If you want to turn the subwoofer off, set the Auto-On switch in the
“Off” position.
SUBWOOFER ADJUSTMENTS: CROSSOVER CONTROL
The Crossover control adjusts the subwoofer’s
built-in crossover between 50Hz and 150Hz. The
higher you set the Crossover control, the higher in
frequency the subwoofer will operate and the more
its bass will “overlap” that of the satellite speakers.
This adjustment helps achieve a smooth transition
of bass frequencies between the subwoofer and
the satellites for a variety of different rooms and
subwoofer locations.
To set the Crossover control, listen for the
smoothness of the bass. If the bass seems too strong at certain
frequencies, try a lower Crossover control setting. If the bass seems too
weak at certain frequencies, try a higher Crossover control setting.
SUBWOOFER ADJUSTMENTS: VOLUME
Use the Volume control to set the subwoofer’s
volume. Turn the knob clockwise to increase
the subwoofer’s volume; turn the knob
counterclockwise to decrease the volume. Once
you have balanced the subwoofer’s volume with
that of the other speakers in your system, you
shouldn’t have to change it.
Notes on Setting Subwoofer Volume:
• Sometimes the ideal subwoofer volume setting
for music is too loud for films, while the ideal
setting for films is too quiet for music. When setting the subwoofer
volume, listen to both music and films with strong bass content and
find a “middle ground” volume level that works for both.
• I f your subwoofer always seems too loud or too quiet, you may want
to place it in a different location. Placing the subwoofer in a corner will
tend to increase its bass output, while placing it away from any walls
or corners will tend to lessen its bass output.
SUBWOOFER ADJUSTMENTS: PHASE
The Phase switch determines whether the subwoofer driver’s
piston-like action moves in and out in phase with the satellite
speakers. If the subwoofer were to play out of phase with the
satellite speakers, the sound waves from the satellites could
partially cancel out the waves from the subwoofer, reducing
bass performance and sonic impact. This phenomenon
depends in part on the placement of all the speakers relative
to each other in the room.
Although in most cases you should leave the Phase switch in the “Normal”
position, there is no absolutely correct setting for the Phase switch. When
the subwoofer is properly in phase with the satellite speakers, the sound
will be clearer and have maximum impact, and percussive sounds like
drums, piano and plucked strings will sound more lifelike. The best way
to set the Phase switch is to listen to music that you know well and to set
the switch in the position that gives drums and other percussive sounds
maximum impact.
