Fender knows the importance of sound reinforcement. From the loudspeaker enclosure
to today's professional touring concert systems, the need to communicate, to make the
connection between the person speaking and the audience is foremost in our mind.
Moreover, we understand that how your message is delivered is just as important as
the message itself. You see, your sound system is more than just a combination of
dials, wires and speakers. It plays an integral part in ensuring that your thoughts and
ideas are heard. Thus, your sound system 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 simply need loudspeaker systems to compliment your existing setup or a
complete sound system, Fender has the sound reinforcement equipment that will 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,

Thank you for purchasing a Contractor Series CS215 Professional Subwoofer from Fender®Pro Audio.
We are sure you will find it both a unique and effective
sound reinforcement product, providing years of
trouble-free service.
Designed for the most demanding sound
contracting requirements, the cabinet’s multiple
cavities and internal wood bracing helps eliminate
side wall movement. This design results in low
distortion, very high power handling and very high
SPL output. Likewise, large ports on the CS-215
cabinet prevent compression at high SPL due to
large exit velocities.
Housed in a sanded unfinished cabinet, the CS-215
offers the flexibility of painting and varnishing the
cabinet to your specifications. Also, a black
annodized pole (p/n 071-1359-000) is available for
placing a mid or high range enclosure over the CS-
215.
-Only use Fender Mounting Pole (P/N 071-1359-
000) to support the full range cabinets.
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 4-Pole Speakon™connectors and the two
1/4" phone jacks are wired in full parallel so that any
one of the connectors may be used as an input and
the other connectors as an output to another
subwoofer. This allows the multiple, cabinets to be
"daisy chained", eliminating the need for several long
runs of speaker cable.
Note: A single CS-215 subwoofer represents a 4Ω
load to the amplifier. Daisy chaining two of them in
parallel will represent a 2Ω load to the amplifier.
Only amplifiers rated for 2Ω output should be used
in this configuration.
The following polarity convention should be used
when making connections to the CS-215:
Polarity Phone Jack Speakon™
Positive (+) Tip 1+ and/or 2+
Negative (-) Sleeve 1- and/or 2-
USING THE CS-215 IN A SYSTEM
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 mid/high racks
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 mid/high
packs. If the subwoofer is placed too far from the
mid/high packs, a slight smearing of the lower bass
frequencies may occur. While ideal placement for
this consideration would involve stacking the
mid/high pack 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
subwoofer hinging in free air is referred to as
operating in "full space" since the subwoofer is free
to radiate in all directions (omnidirectionally). 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".
The CS-215 is designed to augment the low
frequency performance of the main P.A. speakers
using bi-amplification. By reproducing very high
levels of the low bass frequencies, the CS-215
relieves the smaller main speakers from having to
supply this energy.
In order to split frequencies and send certain
frequencies to one type of speaker and other
frequencies to another type, a line-level electronic
crossover, such as a Fender®PCN-2™or PCN-4™, is
required.
Two different configurations are shown on pages 5
and 6, demonstrating how easy it is to add a
subwoofer to a system. Figure 3, on page 7, shows
a more extensive configuration for those set-ups
requiring additional power.
The CS-215 is designed for a "half space"
configuration. Full space operation will result in
about a 3 dB decrease in output as compared to
half space. In order to compensate for the decrease
in output using a full space configuration, the power
amplifier may need to be turned up. 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 mid/high pack mounted either directly
on top of the subwoofer or supported by the
optional pole (Fender P/N 071-1359-000) and using
the subwoofer as a base. In permanent installations,
the CS-215 may be placed under a stage, table or
podium.
For each particular situation, a compromise among
these three factors should yield the best solution
possible.

CROSSOVER SUGGESTIONS
After the speaker system has been placed, the
crossover point needs to be set for maximum
benefit. While the 15" drivers in the CS-215 are fully
capable of accurately reproducing frequencies
above 350 Hz, the bandpass enclosure has been
designed to acoustically roll off frequencies above
170 Hz. This decreases distortion levels and boosts
frequencies below 170 Hz. Thus, the crossover
point should be set lower than 130 Hz to ensure that
all frequencies are reproduced. Setting the
crossover point too low (below 80 Hz) will not take
full advantage of the subwoofer because it places
too high of a demand on the mid/high packs. For
these reasons, a crossover point of ranging between
80 and 130 Hz is recommended depending upon
the placement of the speakers.
The output level of the subwoofer(s) should be
matched by ear to the output level of the full range
cabinets by adjusting the level control at the
crossover (if it has one) or at the power amplifiers.
Normally, the output of the full range cabinets is
subjectively higher than that of the subwoofers so a
balance can be achieved by turning down the
mid/high frequency signal at or before the power
amplifiers.
