HYDRA 7.1 SUPERSUB

1 Technical Specications
Super horn loaded subwoofer with circu-
lar section development, characterized by
extreme sensitivity, dynamics and emission
power, made with an incredibly rigid and
light structure in durable composite mate-
rials. Unlike all other alternatives currently
available, this low frequency loudspeaker
has been realized without technical and di-
mensional compromises, being fully deve-
loped both in terms of length and radiating
surface. Thus it achieves maximum acou-
stic performance combined with an elegant
design and personality, always keeping dy-
namics and control front and center. Nearly
scratch proof surfaces and resistance to at-
mospheric agents combined with extremely
high eciency and world class sensitivity
allow the Hydra to perform favorably com-
pared with any product from the main com-
peting brands. Hydra 7.1 guarantees the
perfect loading of low frequencies in sensi-
tivity, depth, control and SPL expressed by
the usage of few watts. The most common
subwoofers on the market (wooden box
type) are horn loaded speakers with several
internal turns, non-optimized sections and
reduced length, leading to lower sensitivity,
reections that create distortions and rip-
ples, and uneven loading. Therefore they
need corrections by DSP with consequent
mechanical stress caused by the excursion
of the transducer, which creates more di-
stortions while using the enormous amount
of energy needed by the amplier to obtain
SPL. Hydra 7.1 uses a single hi-quality tran-
sducer of 18“(460mm). The structure is ri-
gid, very light (considering the whole weight
and the rate dB/Kg) The scenic impact is
extraordinary and absolutely exclusive and
unique on the professional sound market.
The Hydra 8.1, folded version, is compact
and reduced in height compared to the ver-
tical version. Hydra 7.1 (vertical) and Hydra
8.1 (folded) have similar acoustic perfor-
mance.

2: Unboxing
The Hydra, like every other Pequod product, is
built with high standards of control and quality.
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 Hydra 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 Hydra weighs 80 Kg (176,37 lb) each, and it’s
being shipped contained inside suitable woo-
den packaging box. Its extraction from the box
is achievable by two operators, at least. When
shipped disassembled, follow the instructions at
the end of chapter 4 ( Assembly + anchoring ) ,
about its assembly on site. Keep the packaging
for further storage or transportation, unless units
are to be permanently installed.

3 Wiring and Settings
Hydra has an input made with a female NL4 connector. 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-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 Hydra 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 sq. mm.
Connection diagrams:
A) 1x Hydra (see g.below): Cable between Hydra and amp (not supplied): 2-pole cable (section
2.5 sq mm minimum per pole up to cable length of 15 m, 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 Hydra input, which has an
NL4fc female connector, standard or WP on request.
