If a power-strip or surge protector is used,
make certain that it is rated to accommodate
the Ultra-X13’s power requirements.
6. Reconnect your processor or receiver to the
AC power source.

to learn about the Ultra-X13’s controls and
how they operate.
Connecting to a System without a Subwoofer
Preamp Output, but with Standard Left/Right
Preamp Outputs
If your system does not have a dedicated
subwoofer preamp output, but has left/right
preamp outputs, you can use these jacks to
connect your receiver or processor to the
subwoofer amplifier.
To connect an Ultra-X13 Subwoofer using
standard Left/Right preamp outputs:
1. Turn off all system components and unplug
the processor or receiver and the Ultra-X13
from their AC power source.
2. Locate the “Left/Right preamp outputs” on the
rear panel of your receiver or processor.
Some audio products that do not offer digital
surround processing will have these types of
jacks. If your receiver or processor does not
have this type of output you will need to follow
the “Connecting to a system with no pre-amp
outputs” instructions that follow this section.
3. If using an external power amplifier, connect a
Y-Adapter/Splitter to the left and the right pre-
amp outputs (one for each output). If a
separate amplifier is not being used, connect
a pair of RCA cables to the left and right
preamp output and skip ahead to Step 5.
4. Connect one set of the pre-amp outputs
created by the Y-Adapters/Splitters directly to
your power amplifier with a pair of RCA
cables.
5. Locate the connections labeled “LFE & Line
Inputs” (H) on the rear panel of the Ultra-X13.
6. Connect the remaining pre-amp output
connections to both of the “LFE & Line Inputs”
(H) connections on your Ultra-X13 with a pair
of RCA cables.
7. Plug the Ultra-X13’s power cord into an un-
switched AC outlet.
CAUTION: Due to the power requirements of
the Ultra-X13, it must not be connected to the
accessory outlets on a receiver or processor.
If a power-strip or surge protector is used,
make certain that it is rated to accommodate
the Ultra-X13’s power requirements.
8. Reconnect your processor or receiver to the
AC power source.

to learn about the Ultra-X13’s controls and
how they operate.
Subwoofer Placement
Placement of your subwoofer is a critical
component in maximizing the performance of your
Ultra-X13. Placement influences the subwoofer’s
“perceived” frequency response, sound pressure
level (SPL), and overall accuracy. Since each
listening room differs in virtually every aspect, the
ideal location will also vary.
An easy way to find the right spot to place your
new Ultra-X13 is to experiment with what we call
the “Subwoofer Switch Trick.” This process puts
the subwoofer where you normally sit and then
lets you play the role of the subwoofer.
1. Place the subwoofer as close to your favorite
listening position as possible. If possible,
place the unit in front of your couch or easy
chair, right in the room’s “sweet spot.”
Provided that there is no damage to your
furniture, you may even place the subwoofer
on the chair or couch, but remember that the
Ultra-X13 is heavy, and the Outlaws are not
responsible for any damage to your furniture
or for arguments this might cause with other
members of the household!
2. Activate the test tone from your processor or
receiver’s internal test tone generator, or use
your favorite test disc so that pink noise plays
through the subwoofer. While the test tone is
playing, walk around your room to find the
spots where you hear the best bass response.
Sometimes this may be in the center of the
room, while in other cases you may find the
best spot in a corner or along a side wall.
3. Turn off the test tone and move the subwoofer
to the location where you hear the best bass
response. If that location is unacceptable or
impractical, repeat the procedure to the spot
that is the best compromise between bass
performance and aesthetic considerations.
Notes on Subwoofer Placement
Try to avoid creating a listening position that falls
directly between the front and back walls as this
may cause a strong interference effect due to the
collision between bass waves bouncing off the
