1 Technical Specications
EF5 Twister 3.1 is a passive 3-way horn-loa-
ded system with an extended low- frequen-
cy direct emission component. Professional
HI-PRO two-way audio system with horn-lo-
aded speaker technology, designed to seam-
lessly integrate with dedicated transducers,
built from high resistance composite mate-
rials for elevated sensitivity, dynamics, and
denition. Wide-angle coverage of a highly
controlled sound eld, and the ability to re-
ach high sound levels without perceptible
distortion. The system is characterized by
excellent sound quality the ability to reach hi-
gh-pressure ranges. A pair of large full-frontal
horns manage the high-mid frequency ran-
ge through a dedicated passive crossover(or
using a 2 ch amplier+DSP). The high-range
horn is characterized by a special high-end
derivation design. The long and complex de-
velopment with variable sections allows a
wide dispersion with powerful loading. The
Shockwave 2.1 mid-range horn has a uni-
que design that creates an extraordinary le-
vel of eciency and sensitivity. This allows for
excellent dynamics that distinguish the entire
system from the very rst listen. The extended
low-frequency direct emission component is
characterized by a light structure with a highly
resistant ovoid shell, containing a 15 “woo-
fer with a 30-400 Hz range and high sensiti-
vity. This component can alone cover the mid
and low frequencies or can be assisted by
additional subwoofers to cover the lower fre-
quencies with additional power. The LF driver
features a water-resistant cone. Components
such as the speakers, woofers, and compres-
sion drivers all represent world-class quality,
without commercial or technological compro-
mises. Thanks to its elevated sensitivity, the
system requires limited amplication power.
The EF5 Twister system is manageable throu-
gh bi- amplication with DSP for managing
cuts between the high-mid and low routes.
The two high-mid horn components are ma-
naged passively by a specic crossover lter.
A Full-Fat audio FFA 8004 is the recommen-
ded 4 channel amplier partnered in this sy-
stem (stereo conguration) with a dedicated
DSP. Otherwise, it can be managed actively
by three ampliers and by traditional DSP. Any
additional subwoofers are sold separately.

2: Unpacking
The Twister, like every other Pequod product, is built
with high standards of control and quality. At the end
of the production process and before packaging,
each system is tested: acoustically measured and
recorded in our company database. For each Twister
serial number, we have the related test les recor-
ded 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 heavy
cardboard boxes with internal foam padding before
shipping.
Extraction from box:
The Twister weighs: 14 Kg (31 lb) mid-high compo-
nent, 22 Kg (48 lb) low component each, and it’s
being shipped contained inside suitable wooden
packaging box. Its extraction from the box is achie-
vable by two operators, at least.

3 Wiring and Settings
The Twister has 3 inputs made with a female NL4 connector. The mid + hf part is connected to the crossover
(housed in a crossover box of 3 types: standard box, cod.STBOXTWI; metal rack box, cod. RBOXTWI ; wea-
therproof box ,cod.WPBOXTWI ) by Y cable (if purchased from Pequod it is the code CAB03TWI) thus made:
two 2-pole cables (minimum section 2.5 sq.mm per pole, for cable lengths up to 15m), terminated with 2
male connectors (A and B) NL4FC (+ 1 / -1 connected , + 2 / -2 empty), merged into a single 4-pole cable
(minimum section 2.5 sq.mm per pole) terminated with 1 male connector (C) NL4FC (+ 1 / -1 connected, +
2 / -2 connected ) . See diagram below :

1) Cable between crossover 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 per pole), ter-
minated with Nl4Fc male connector ( + 1 / -1 connected and corresponding to +1 red and -1 black
on the amplier, + 2 / -2 empty) to connect at the crossover input, which has NL4 female connector,
standard or WP on request.
2) Cable between Ovoid15 ”and amp (not supplied):
as above. 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
more than 15 meters between xover and ampliers 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.

4 Installation and system design
Twisters can typically be used as a high quality system for listening areas, like a dance oor or for
a medium-sized audience of a live concert. In some cases it is necessary to use suitable subwoo-
fers (Ovoid or Hydra available from the Pequod catalog) to have a full range system. For on stage
installation facing an audience, they can be housed on their stand or, above the subwoofer (like
Ovoid18) for easy management and handling

4 Installation and system design
It should be borne in mind that optimal acoustic coverage is obtained by lifting the Twisters 2 -4 m
from the ground on the vertical plane, tilting them towards the audience, so that the ideal outgoing
axis between the HF and MF horns is oriented in an area placed between 1/2 and 2/3 of the depth
of the area to be soundtracked (dance oor or audience). On the horizontal plane, it is also neces-
sary to orientate the ideal axis coming out from Twister in an area that is placed at about 2/3 of the
depth of the area to be covered, on the center line of the area itself.

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 dierent Pequod units. For
these components, we recommend cleaning
with 3M
TM
Stainless Steel Cleaner and Polish (ri-
ght).
