3x18” Bass reex subwoofer

1 Technical Specications
The Cerberus system is a bass Reex
subwoofer consisting of 3 18-inch
long-excursion woofers housed in three
ovoid volumes structure connected
and fused to form an extremely light
and rigid monolithic structure. The to-
tal power of the system is over 10000
Watts, having very high sensitivity (102
dB / W / 1m) With a total radiant surfa-
ce equivalent to a 32-inch diaphragm.
The composite material by which it is
composed allows for high stiness and
avoids the triggering of resonances of
the speaker walls. Compared to a tra-
ditional subwoofer made of wood, the
Cerberus system does not present har-
mful structural vibrations, as well as ha-
ving very high resistance to atmospheric
agents. The shape itself without parallel
walls avoids the formation of internal
standing waves with considerable ad-
vantages for having a clean and precise
sound. The Cerberus system is suitable
for creating full-range systems with high
acoustic impact. Ideal for forming a sy-
stem with Shockwave, Polyphemus,
and Kona products, where quality and
power are achieved through a compact
Subwoofer, compared to the conside-
rable power itself expressed. Although
the 3 18-inch woofers can be driven in-
dividually with 3 amplication channels
(version with 4-ohm impedance for each
18-inch, Cod.CERB04), we recommend
the setup in a parallel.

2: Unboxing
The Cerberus, like every other Pequod product,
is built with high standards of control and quali-
ty. At the end of the production process and be-
fore packaging, each system is tested: acousti-
cally measured and recorded in our company
database. For each Cerberus serial number, we
have the related test les recorded in the archi-
ve. Before being packed in its box we complete
an inspection of surfaces and structures. Units
are packed into wooden crates or heavy card-
board boxes with internal foam padding before
shipping.
Extraction from box:
The Cerberus weighs 84 Kg (185 lb) each, and is
taken from the box simply following the steps
shown here.
Keep the packaging for further storage or tran-
sportation, unless units are to be permanently
installed.

3 Wiring and Settings
Cerberus has inputs made with connectors NL4 female. Through a dedicated cable and terminated with 2 male
NL4Fc connectors it is connected directly to the output of the power amplier. The connectors are standard NL4
(+ 1 / -1 connected + 2 / -2 empty) or water proof on request.
In case of custom realization by the installer of the connection cables, we recommend specifying installation-gra-
de Low Smoke Zero Halogen (LSZH) cables for permanent installations. The cables should use Oxygen Free
Copper (OFC) of grade C11000 or above.
For distances of over 15 meters between Cerberus and ampliers, we recommend increasing the section of the
cable poles to 4 sq mm, to avoid excessive emission level losses. For lengths less than 15 m, you can use 2-pole
cables, each with a section of 2.5 sq mm.
Connection diagrams:
A) Single connection for every 18 “(3 identical cables in total, see g. Below): Cable between each sub Ovoid
and amp (not supplied): 2-pole cable (2.5 sq mm minimum section per pole up to cable length of 15 m, over we
recommend switching to 4 mmq per pole), terminated with male connector Nl4Fc (+ 1 / -1 connected and cor-
responding to +1 red and -1 black on the amplier, + 2 / -2 empty) to connect at the imput of each Ovoid sub,
which has an NL4 female connector, standard or WP on request.

empty). Sections of poles: 2.5 sq mm minimum
section per pole up to a cable length of 15 m, in
addition we recommend switching to 4 sq mm
per pole.
2x Secondary cables, 2 poles, which connect
the 3 sub Ovoids together. Terminals made with
male NL4 connectors (+ 1 / -1 connected + 2 / -2
empty). Sections of the poles: section 2.5 mmq
per pole and cable length of 1.5 m

4 Installation and system design
Cerberus can typically be used as a very high
quality system for sounding listening areas, such
as a dance oor or for an audience of a live con-
cert. In all cases it is necessary to use suitable
satellites (Polyphemus, SWave, Kona, Twister
available from the Pequod catalog) to have a
full range system. Cerberus represents the opti-
mal choice as a subwoofer to be combined with
the Polyphemus or Swave (or With Kona Storm,
Twister, Ostro, having a surplus of power right
on the subwoofer), to have a full range system,
of high quality and global sensitivity.
The gure shows the typical combination, with
Polyphemus, Kona and Twister.
Refer to the Polyphemus, Kona, and Twister
manual for further details.

In Indoor systems:
In Indoor systems we recommend placing the
Cerberus against the wall (wall position) or in a
corner position, to avoid harmful (for the purpo-
ses of emission regularity) reections of acou-
stic waves and increase the overall performance
of the system.

Assembly + anchoring:
As for the assembly and possible anchoring
of Cerberus during installation, the subwoofer
must be placed in its frame, inserting the tube
in the lower seat of the sub. If necessary, there
is the possibility of anchoring the feet of the fra-
me to the ground, by means of screws, metrich
thread M6, screwed between oor and M6 thre-
aded insert, placed in each foot of the product.

6: Maintenance and Surface Protection
All Pequod units are built from a unique high
quality composite material which is inert to at-
mospheric agents and requires minimal regular
maintenance, just a simple cleaning of the sur-
faces with a soft cloth dampened with alcohol.
For best practice in long term care of the com-
posite components, and to obtain or restore
a truly professional level of surface nish, we
recommend using the 3M “Perfect ItTM” line of
Gelcoat cleaners and protective waxes (above
right).
Follow the instructions provided to ensure the
best possible nish for your Pequod composite
speaker bodies and accessories.
Many installations require Stainless Steel sup-
port structures or armatures to complete moun-
ting and assembly of dierent Pequod units. For
these components, we recommend cleaning
with 3MTM Stainless Steel Cleaner and Polish (ri-
ght).

8: Authentication and Anti Counterfeiting Me-
asures
Each product by Pequod Acoustics is carefully
hand made using high quality components that
are, by themselves, dicult to replicate. But we
also protect our products using special marks
on the inside and outside, which are unique and
serve to authenticate original Pequod products.
Thus, each individual product has a special
mark, placed in a unique position. For each pro-
duct (each serial number) we keep a record of
the exact position where we placed this mark.
When warranty claims are made, or other reque-
sts that require authentication of an individual
Pequod product, we will ask the owner to pro-
vide a description of the identifying marker as
further proof of originality.
