This may restrict driver movement and will cause damage to your LFM that  
is not covered by the warranty.  
When using the subwoofer on surfaces such as wood floors and certain tight  
weave rugs, be sure to use the supplied dimpled discs to prevent damage to  
floor's surface. You are responsible for determining when use of these discs  
is required.  
Make sure to insert all plugs and connectors securely. Improper connections  
can result in noise, poor performance, or damage to the equipment.  
Do not bundle the subwoofer cable or speaker wire with the power cord. This  
may adversely affect the sound quality and introduce unwanted hum into  
your system.  
Installing Subwoofer Feet  
Proper installation of the supplied feet/carpet spikes is necessary for ALL LFM  
subwoofer setups. These spikes provide the ground clearance that is required for  
optimal performance and safety. Failure to use the feet provided will result in  
damage not covered under the Outlaw Audio Warranty. For your convenience  
we have provided “dimpled discs” that may be used when the LFM is placed on  
surfaces other than carpet, such as wood, tile, certain rugs and linoleum surfaces  
to prevent damage to the floor or floor covering.

Setup Guide  
Connecting to Your System  
To get the maximum performance from your new LFM subwoofer it must be  
connected and, positioned properly within the room and configured to match  
your speakers. To connect an LFM Series Subwoofer you will need either a single  
audio interconnect cable (in the case of systems with a subwoofer output) or ad-  
ditional speaker wire. We recommend the Outlaw Audio PCA SUB cable, but any  
high quality, shielded audio interconnect will work properly.  
Connect the subwoofer output of your receiver, processor or other source  
device or accessory to this jack.  
HIGH LEVEL Inputs  
When your receiver does not have line level outputs available for a subwoofer  
connection, connect the speaker outputs of the receiver here.

If a low-level subwoofer output is available, use this jack to connect your LFM  
subwoofer to your Preamp or Receiver. See Diagram 1 on page 6.  
HIGH LEVEL Outputs  
When the speaker level inputs are used, connect the main speakers to these  
terminals.  
K
Power Cord Jack  
Connect the supplied AC power cord here, and then connect the plug end to  
an un-switched AC wall output. Should the power cord need replacement,  
make certain it is replaced with a cord having the identical power rating.  
To connect the LFM to a subwoofer preamp output:  
1. Turn off all system components and unplug the processor or receiver  
and the LFM from their AC power source.  
L
Fuse Housing  
Containsa20mm3.15Aslowblowfusethatprotectsthesubwoofer. Intheevent  
that it must be replaced, be certain that a fuse with the same rating is used.  
ꢀ. Locate the “Subwoofer/LFE Output” on the rear panel of your receiver  
or processor.  
M
MASTER POWER Switch  
Any audio product that decodes Dolby Digital or DTS soundtracks will have  
this type of jack. Depending on the particular brand or model, this RCA  
jack may be labeled “Sub,” “Subwoofer,” or “LFE Out.” If your receiver  
or processor does not have this type of output you will need to follow the  
“Connecting to a System with No Preamp Outputs” instructions that  
follow this section.  
Use this switch to turn the LFM subwoofer on or off. When the unit will not be  
used for extended periods, we recommend turning this switch off to prevent  
accidental activation.  
Subwoofers, Bass and  
Overall System Performance  
The goal of an audio system is to recreate the source material as accurately as  
possible. The components needed to perform this task are an audio source, a  
receiver or processor/amplifier combination, and speakers.  
ꢁ. Connect one end of the subwoofer cable to the subwoofer or LFE output  
on the receiver or processor.  
4. Locate the connection labeled SUB IN on the rear panel of the subwoofer  
and connect the other end of the subwoofer cable to that jack.  
In the era of digital, multi-channel sound, many listeners have chosen to use  
frequency-limitedsatellitespeakersforthefront, centerandsurroundchannels.  
By limiting their frequency range, these speakers may be made smaller, to more  
easily fit into a wide range of spaces. However, by eliminating the capability to  
reproduce bass frequencies, a separate speaker that is custom designed to deal  
with signals below 200Hz is required. That speaker, along with its companion,  
built-in amplifier is a powered subwoofer.  
5. Plug the LFM’s power cord into the input on the LFM Series Subwoofer  
and connect the plug to an un-switched AC outlet.  
CAUTION: Due to the power requirements of the LFM, 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 your LFM’s power requirements.  
6. Reconnect your processor or receiver to the AC power source.  
Even in two-channel systems with traditional bookshelf or tower speakers the  
bottom two octaves of sound (20 Hz to 80 Hz) are frequently rolled off or not  
reproduced at all. Here, too, a specialized speaker/amplifier combination is  
required to deliver the full spectrum of sound from a system.  
7. Proceed to the “Setting The LFM’s Controls” section to learn about the  
LFM’s controls and how they operate.  
Finally, many multi-channel digital soundtracks contain a special audio channel  
devoted specifically to extreme low frequency extension. This signal is the “.1” in  
5.1, 6.1 and 7.1 systems and is sometimes referred to as the LFE channel.  
Regardless of which of these situations create the need, a subwoofer is absolutely  
essential for accurate audio reproduction of both movies and music. A properly  
designed subwoofer such as an Outlaw LFM Series Sub can provide a visceral  
impact that most speakers are not able to provide on their own. No matter what  
type of speakers comprise the rest of your system, or what your favorite movie or  
music is, the LFM series subwoofers complete the sonic presentation by providing  
the impact that only a subwoofer can deliver.

Setting the Variable Tuning LFM Series Subwoofer’s Controls  
An easy way to find the right spot to place your new Variable Tuning LFM Series  
Subwoofer 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.  
Connecting to a System with No Preamp Outputs  
If no low-level subwoofer output is available, you will need to run speaker wires  
from your main amplifier or receiver to the subwoofer amplifier. See Diagram 2  
on page 6.  
First, placethesubwooferasclosetoyourfavoritelisteningpositionaspossible. This  
should be directly 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 LFM Series Subwoofers are  
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!  
To connect a Variable Tuning LFM Series Subwoofer using  
high level inputs:  
1. Turn off all system components and unplug the receiver and/or amplifier  
and the LFM from their AC power source.  
ꢀ. Locate the front left/right speaker output terminals on your receiver or  
Second, 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 and 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 sidewall.  
amplifier.  
IncaseswheretherearebothAandBterminals,theAterminalsshould  
be used. Disconnect any wire that is presently connected to these terminals.  
ꢁ. Using the same type of speaker wire used for your other speaker  
connections, connect the left and right channel speaker outputs of  
your receiver or amplifier to the LFM’s High Level Inputs.  
Finally, 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.  
Be sure to connect the speaker wires to the appropriate input binding  
posts on the back of the LFM, making certain that the polarity (–/+) on  
the receiver or amplifier matches the polarity on the binding posts of the  
subwoofer amp. In most cases this means connecting the red terminal  
on the receiver or amplifier to the red terminal on the LFM, but always  
check the markings on the rear panel to insure “+ to +” and “– to –”  
connections. Also, make sure that the negative outputs on your main amp  
are true ground; otherwise you would short the output of your main amp.  
Call or email tech support if the negative outputs on your main amplifier  
do not have true ground.  
Notes On Subwoofer Placement  
Try to avoid creating a listening position that falls directly between the front  
and back walls. This may cause a strong interference effect due to the collision  
between bass waves bouncing off the rear wall and new waves emanating from  
the LFM. When this happens you might hear an unnatural “build up” in the low  
frequencies where the bass sounds “bloated”, based on the specific dimensions of  
the room and the particular frequency being reproduced.  
4. Connect the speaker wires to the high-level output terminals on the  
back of the LFM Series Subwoofer.  
In other situations you might encounter a “null”, which is caused by two low fre-  
quency waves canceling each other out. When this happens you will find that your  
favoritelisteningpositionisbassshy.Inthistypeofplacementsituation,bassresponse  
will suffer greatly regardless of how powerful the subwoofer is. The best way to solve  
this problem is to change the location of the seating position so that the distance to  
the front of the room is different than that to the back of the room.  
Make certain that the polarity (–/+) on the subwoofer's high-level output  
terminals match the polarity on the binding posts of the speakers. Also,  
be sure to prevent any positive and negative strands of speaker wire from  
crossing.  
5. Plug the LFM’s power cord into the input on the LFM Series Subwoofer  
and connect the plug to an un-switched AC outlet.  
Setting the Variable Tuning LFM Series  
Subwoofer's Controls  
CAUTION: Due to the power requirements of the LFM Series Subwoof-  
ers, they 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 LFM’s power requirements.  
Variable Crossover  
By adjusting the variable crossover on the LFM, you can perfectly match your LFM  
Series Subwoofer to your main speakers. If your receiver or processor already has  
a built in crossover, disable the crossover on the LFM by flipping the “X-OVER”  
switch to the “BYPASS” position. Refer to the owner’s manual for your receiver  
or processor to see how to disable any internal crossover capability it may have.  
If your receiver or processor does not have internal crossover control, follow these  
steps to set LFM’s variable crossover:  
6. Reconnect your receiver and/or amplifier to the AC power source.  
7. Proceed to the “Setting The LFM’s Controls” section to learn about the  
LFM’s controls and how they operate.  
Subwoofer Placement  
Placement of your LFM series subwoofer is a critical component in maximiz-  
ing its performance. The subwoofer's specific location in a room influences its  
“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.  
Determine the +/- 3dB point of your main speakers. This frequency is usually  
found on the speaker’s specifications sheet or may often be available on the  
speaker manufacturer’s web site. Start with the crossover set approximately to  
this point. By experimenting with the crossover frequency and level control, you  
can fine-tune the LFM Series Subwoofer so that there is a seamless link between  
the LFM and the main speakers.

If the actual +/- 3dB point cannot be obtained from the speakers’ specifications  
or the manufacturer’s web site, you can use the following chart as a guideline:  
40 Hz  
Large tower speaker with one 12 or 15-inch woofer or  
two 10-inch woofers;  
Why Two Subwoofers?  
In most circumstances two subwoofers will perform better than one. While you  
might assume this is for added SPL, the greatest benefit will actually be smoother  
bass response.

Small tower or large bookshelf speaker with one 8-inch or two 6-inch  
woofers:  
Room shape, the cubic volume of the room (width x depth x height), furniture,  
floor coverings and even wall and ceiling material all play a roll in bass per-  
formance. These factors create peaks and dips in the level of low frequencies at  
different points in the room. That said, two properly positioned subwoofers will  
distribute the bass throughout the room with greater accuracy than a single sub.  
For this reason many professional acousticians and installers recommend more  
than one subwoofer. The final result is that you will create a much larger “sweet

more bass-heavy. The bass-heavier position is the setting where the output of the  
LFM and the main speakers are most in phase. Use program materials with bass  
in the crossover region such as music containing bass drums, double basses, bass  
guitar, etc., to determine the correct setting.  
Most of today’s digital receivers and preamp/processors provide a single subwoofer  
output. Connecting two subwoofers to these systems is as simple as adding a Y-  
adapter. A Y-adapter splits a single output into two separate outputs. Be sure to  
use a Y-adapter that is of equal or better quality than the subwoofer cables you  
intend to use. (We recommend the Outlaw Audio PCA Y-Adapter.)  
Port Switch  
Depending on your bass preference, your Variable Tuning LFM Series subwoofer  
has two separate "tuning" modes. In Its “Max Output” mode your LFM series  
subwoofer will provide the greatest level of overall bass in regards to SPL (sound  
pressure level). In Its "Bass Extension" mode your LFM series subwoofer will  
provide the deepest bass (low frequency) levels. When using the Bass Extension  
mode you will need to ensure that the provided “port plug” Is blocking one of  
the ports located on the bottom of the subwoofer. In the Max Output mode, both  
ports should remain unplugged.  
To use the Y-adapter, insert the single male end of the cable to the subwoofer  
output of your receiver or processor. On the opposite end of the Y-adapter you will  
now have two separate subwoofer outputs, one for each sub.  
Placement and Level Control  
Placement and level control of two subwoofers is somewhat more complicated  
than using a single subwoofer. However, the end result of two properly placed and  
calibrated subwoofers is well worth the added effort.  
The procedure for placement of the second subwoofer is identical to that of de-  
termining the placement of the first subwoofer (see the “Subwoofer Placement”  
section of this manual). However, the second sub should be placed in the seating  
area outside of the “sweet spot” where good bass response is also required. Walk  
around the room until you find the area where the bass sounds the best, just as  
described in the process for locating a single sub. This spot will almost always be  
different than the one that was best for the primary sub.  
CAUTION: Do not leave both ports open when the Port Switch Is In  
the “Bass Extension” position as your subwoofer's performance will be  
comprised. If one of the ports is blocked using the supplied port plug, the  
Port Switch must remain In the “Max Output” mode. Failure to adhere to  
these requirements can lead to poor performance and damage to your  
subwoofer.  
Volume Level  
NOTE: When calibrating your second subwoofer be sure to turn off the first  
sub. This will help you to determine ideal placement without being mislead  
by the response of the first sub.  
Using the built-in test tones of your receiver/processor, match the levels of all of  
your speakers including your LFM Series Subwoofer as described in your receiver  
or processor’s owner’s manual. A setting of 5 on the LFM’s volume knob should  
provide enough gain to properly match the sub level to your speakers. We recom-  
mendusinganSPLmetersuchastheRadioShackmodel(partnumber33-2050).  
When using the test tones, measure from the listening chair and set the meter to  
the 75 dB level. In order to accurately measure levels between channels use “C”  
weighting and the “slow” setting.  
When calibrating the final levels of each subwoofer, you may want to reduce  
their output to compensate for the added 3 or 4 dB of gain created by using two  
subwoofers together.  
If you sense a loss of bass output after properly locating and calibrating both  
units in a two subwoofer system the likely problem is that the two units are out  
of phase with each other. If this occurs try flipping the phase switch on the back  
of one or both of the subwoofers until the bass returns. For more information  
regarding the phase control function, please read the “Setting the LFM’s Controls”  
section of this manual.  
Note that the Radio Shack meter is down about 12 dB at 16 Hz, 7 dB at 20 Hz,  
and 4 dB at 25 Hz. Add these numbers to the readout to compensate for these  
errors if necessary.

problem that may require service assistance, call us at 866-688-5292.  
When You Are Away  
If you will not be using your home theater system for an extended period of time,  
it is always a good idea to turn the unit off using the Master Power Switch on the  
rear panel of the subwoofer. This will prevent the automatic turn on circuits from  
accidentally powering the system on during your absence.  
It is important that only a service agent authorized by Outlaw Audio carry out any  
repairs. Keep your sales slip or receipt in a safe place with this manual so that it  
will be available to verify the purchase date, should you experience a problem  
covered by our warranty.

Problem  
Solutions  
Humming or Buzzing Noise  
Power down your system and remove the Interconnects between your components. Power your  
system back on. If the hum goes away when the interconnects are disconnected, the hum is  
coming from the rest of your equipment. Plug In the Interconnects one at a time for each  
component until you come across the specific component generating the hum.  
No output from the subwoofer  
(the LED does not light up)  
Check that the power cord is plugged in securely at both ends and make sure that the power  
outlet the subwoofer is plugged into is functioning properly.  
Check the fuse. The fuse is located just above the power plug on the subwoofer. Unplug the power  
cord and remove the fuse holder with a screwdriver and check the fuse. If the fuse is blown, replace it  
with a 20 mm 3.15A slow blow fuse.  
If the fuse blows again, the output transistors are probably damaged. Email or call technical support for  
further assistance.  
The subwoofer is not receiving a signal  
(Red light does not turn green)  
Recheck the connections between the receiver/processor and the subwoofer. On the back of the  
subwoofer, make sure the power switch is set to "auto" or "on".  
No output from the subwoofer (LED lights up red)  
Connect the signal cable to another subwoofer or amplifier. If you get output, then the amplifier is  
faulty. Email or call technical support for authorization to send the amplifier back for service.  
No output from the subwoofer (LED turns green)  
With the subwoofer power cord removed, disconnect the woofer and make sure that the two  
speaker wires that come from the subwoofer amplifier are securely connected to the woofer.  
If they are not, secure them or call/email technical support for assistance.
