Fender knows the importance of sound reinforcement. From the simple box-top mixer
to today's professional touring concert systems, the need to communicate, to make the
connection between the performer and the audience is foremost in Fender's mind.
Perhaps no other single piece of gear can make or break your band's sound. You see,
your sound system is more than just a combination of dials, wires and speakers. It is
an integral part of the audio chain and should be treated with special care and attention
to detail.
At Fender, we know what building quality musical instruments and sound reinforcement
equipment is all about. In fact, many of the world's best sounding electric musical
instruments and sound reinforcement equipment proudly wear the Fender name.
Whether you need a simple box top powered mixer for your Saturday afternoon jam, or
a professional full-size concert system, Fender has the sound reinforcement equipment
to meet your needs. Likewise, your decision to purchase Fender pro audio gear is one
you will appreciate with each performance for years to come.
Wishing you years of enjoyment and a heartfelt thank you,
Bill Schultz

Thank you for purchasing an Artist Series
115sA/118sA Professional Subwoofer from Fender
Pro Audio. We know that your music is important to
you. With the addition of this subwoofer, your music
will be reproduced as it was meant to be...Full, well
rounded, and balanced throughout the frequency
spectrum.
Featuring one 15” (115sA) or 18” (118sA) woofer
with a 2.5 “ voice coil and parallel high current 1/4”
jacks that allow you to “daisy chain” other
subwoofers or full range speakers to your system.
The sA’s bandpass design naturally rolls off high
frequencies so there is no need to use a passive or
active crossover network in multi-speaker systems.
The single reflex enclosure design provides for high
sensitivity, high power handling and excellent low
frequency response.
Please read through this owner’s manual in order to
more thoroughly understand the operation, and
applications of your 115sA/118sA professional
subwoofer.
CAUTION: Almost all speakers produce strong
magnetic fields which may interfere with the
normal operation of nearby electronic devices,
including televisions and computer video
monitors. To reduce or eliminate interference,
increase the distance between this product and
other nearby electronic devices.

CONNECTIONS
SETUP SUGGESTIONS
The two 1/4" phone jacks on the 115sA/118sA are
wired in full parallel so that any one of the connectors
may be used as an input and the other connector as
an output to another enclosure. This allows multiple
cabinets to be "daisy chained", eliminating the need
for several long runs of speaker cable.
Note: A single 115sA/118sA subwoofer represents
an 8Ω load to the amplifier. Daisy chaining two of
them in parallel will represent a 4Ω load to the
amplifier. Only amplifiers rated for 4Ω output should
be used in this configuration.
The following polarity convention should be used
when making connections to the 115sA/118sA:
Polarity Phone Jack
Positive (+) Tip
Negative (-) Sleeve
USING THE 115sA/118sA IN A SYSTEM
The 115sA/118sA is designed to augment the low
frequency performance of the main P.A. speakers.
The single reflex bandpass design of these systems
automatically rolls off the high frequencies
eliminating the need for an active or electronic
crossover network. Thus, the subwoofers can be
wired directly in parallel with almost any full-range
speaker system.
Nonetheless, a line-level electronic crossover, such
as a Fender®PCN-2™or PCN-4™,can be used in
order to split frequencies and send mid/high
frequencies to a full-range speaker system and low
frequencies to a subwoofer. By reproducing high
levels of low bass frequencies, the 115sA/118sA
relieves the smaller main speakers from having to
supply this energy. If a crossover is used in your
set-up, make sure that the crossover point is
between 100/120 Hz to ensure maximum
efficiency from your 115sA/118sA.
The placement of any speaker can dramatically
affect its sound. Thus, there are three primary
considerations to review when placing subwoofers.
The first is time alignment. The full-range speaker
system should be as close as possible to the
subwoofer so the sound from the subwoofer
reaches the audience at the same time as the sound
from the full-range speaker systems. If the
subwoofer is placed too far from the full-range
speaker systems, a slight smearing of the lower
bass frequencies may occur. While ideal placement
for this consideration would involve stacking the fullrange speaker on top of the subwoofer, this effect is
quite subtle and an obvious effect may not be heard
until the separation between the two cabinets is large
enough to cause an audible time delay.
The second consideration is to try to obtain as
much bass as possible from the subwoofer. A
speaker in the middle of the floor or up in the air with
its back against a wall is referred to as operating in
"half space". Placing a speaker near a large, flat wall
and on the floor (quarter space) will boost the bass
performance by about 3 dB as compared to half
space. The more surfaces the subwoofer is placed
against, the fewer the number of subwoofer
enclosures are needed to achieve a desired SPL.
The third consideration is convenience and the
visual aspect of the speaker array. For temporary
installations, the subwoofer can be used as a
support for a full-range speaker system mounted
directly on top of the subwoofer. Use only the 27”
Fender Mounting Pole (P/N 711327) which has
been specifically designed for use with both the
115sA/118sA subwoofer enclosures. In
permanent installations, the 115sA/118sA can be
placed under a stage, table, or podium.
For each particular situation, a compromise among
these three factors should yield the best solution
possible.
Two different configurations are shown on pages 5
and 6, demonstrating how easy it is to add a
subwoofer to your system. Figure 3, on page 7,
shows a more extensive configuration for those setups requiring additional power.
