1 Technical Specications
The Ovoidal 4.1 sub is a long excursion
bass-reex subwoofer in an ovoidal axi-
symmetric closed structure, characte-
rized by extreme sensitivity, dynamics,
and emission power, made with an in-
credibly rigid and light structure in du-
rable composite materials. Unlike all
other alternatives currently available,
this low-frequency speaker was made
without technical and dimensional com-
promises, with structural technologies
not present in the professional audio
market. Thus it achieves maximum
acoustic performance with an elegant
design and a unique personality.
All other bass reex subwoofers on the
professional audio market are built insi-
de wooden box structures. This tech-
nology is awed due to structural reso-
nances and internal acoustic problems
related to stationary waves. Furthermo-
re, the wooden structure is very heavy
and is characterized by problems rela-
ted to protection and durability, with lit-
tle resistance to atmospheric agents.
Ovoidal 4.1 represents an exclusive
technological innovation, built from hi-
gh-quality composite materials in a
special ovoidal shell shape. The scra-
tch-resistant glossy surfaces and the
resistance to atmospheric agents, com-
bined with great power with extremely
high eciency and very high sensitivi-
ty, allow Ovoidal 4.1 to truly distingui-
sh itself when compared to any product
from the main competing brands, with
direct radiation electroacoustic bass-
reex technology. Ovoidal 4.1 guaran-
tees perfect loading of low frequencies
in sensitivity, depth, control, and SPL
expressed by the usage of very few wat-
ts. Ovoidal 4.1 uses a single hi-quality
transducer of 15” (390mm). The structu-
re is rigid and very light (considering the
overall weight and the dB/Kg ratio). The
aesthetic impact is extraordinary and
absolutely unique in the professional
sound market.

2: Unboxing
The Ovoid 15 system, like every other Pequod
product, is built with high standards of control
and quality. At the end of the production pro-
cess and before packaging, each system is te-
sted: acoustically measured and recorded in our
company database. For each Ovoid 15 serial
number, we have the related test les recorded
in the archive. Before being packed in its box we
complete an inspection of surfaces and structu-
res. Units are packed into wooden crates or he-
avy cardboard boxes with internal foam padding
before shipping.
Extraction from box:
The Ovoid 15 weighs 20 kg 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
Ovoid 15 has an input made with a female NL4 connector. Through a dedicated cable and termi-
nated 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-grade 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 Ovoid15 and ampliers we recommend increasing the
section of the cable poles to 4 sq mm, to avoid excessive emission level losses. For lengths of less
than 15 m, you can use 2-pole cables, each with a section of 2.5 sqmm.
Connection diagrams:
A) 1x Ovoid15 (see g.below): Cable between Ovoid15 and amp (not supplied): 2-pole cable (2.5
sq mm minimum section per pole up to 15 m cable length, in addition we recommend switching to
4 sq mm for pole), terminated with Nl4Fc male connector (+ 1 / -1 connected and corresponding to
+1 red and -1 black on the amplier, + 2 / -2 empty) to connect to the Ovoid15 input, which has an
NL4fc female connector, standard or WP on request.

poles: 2.5 sq mm minimum section per pole up
to a cable length of 15 m, in addition we recom-
mend switching to 4 sq mm per pole.
1x Secondary cable, 2-pole, which connects the
2 Ovoid 15s together.
Terminals made with NL4 male connectors
(+ 1 / -1 connected + 2 / -2 empty). Sections of
poles: section 2.5 mmq per pole and cable len-
gth of about 1.5 m

4 Installation and system design
The Ovoid15 can typically be used as a very
high quality system to sonorize listening areas,
such as a dance oor or for an audience of a
live concert. In all cases it is necessary to use
suitable satellites (Polyphemus, Swave, Kona
available from the catalog Pequod) to have a
full range system. Ovoid15 represents the opti-
mal choice as a subwoofer to be combined with
the Kona Storm, Twister, Ostro (or for Polyphe-
mus or Swave by increasing the number of Sub
Ovoid15 for each satellite, to balance the emis-
sions), to have a full range system, of high qua-
lity and global sensitivity.
The gure shows the typical combination, with
Kona, Twister and Ostro.

In Indoor systems:
we recommend placing the Ovoid15 against
the wall (wall position) or in a corner position,
to avoid harmful (for the purposes of emission
regularity) reections of acoustic waves and in-
crease the overall performance of the system.

Assembly + anchoring:
As for the assembly and possible anchoring of
Ovoid15 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 3 feet of the frame to the ground, by means
of screws, metric thread M6, screwed between
the oor and the threaded insert M6, placed in
each foot of the product.
