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.
In the era of digital, multi-channel sound, many listeners have chosen to use frequency-
limited “satellite” speakers for the front, center and surround channels. 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.
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.
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.

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.

Connecting to a System with a
Subwoofer Preamp Output
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.
subwoofer to your Preamp or Receiver. See Diagram 1 on page 6.
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.
. Locate the “Subwoofer/LFE Output“ on the rear panel of your receiver
or processor.
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.
