Xa-Systems 2005_e.qxd
The FX 12 is conceived as a fully horn-loaded and coaxial
2-way high-power top and covers the frequency range from
100 Hz to 19 kHz with a maximum sound pressure level of
134 dB / 1m. The HF range from 1 kHz upwards is reproduced by a Neodymium ND 6-8 driver with a 3” voice coil and
a CDH 8040-14 Constant Q horn, whilst coverage in the midrange from 100 Hz to 1 kHz is provided by a neodymium
ND 12A driver with a conical midrange horn.
Extremely low distortion and the minimum of comb-filter
effects, whether multiple tops are stacked or flown, are decisive
arguments in favour of conical horns. A fully electronic voicecoil tracking protection system provides permanent monitoring of the operating state of the individual loudspeakers, and
only in the event of overload is the power gently reined back
to safe values. The result is the maximum possible dynamic
range combined with the highest operational security.
The enclosure is constructed from multi-ply 15mm poplar plywood and is covered with an extremely hard-wearing needle
felt. Secure protection for the front of the enclosure is provided
by a powder-coated metal grille with an acoustic foam front.
Handles at the side and four large rollers on the back afford
extra handling comfort.
Flying rails and fittings for load straps are integrated as standard. Foolproof connectivity is provided by the 4-pin Speakon
cables with system pins that permit reliable communication
between the FX 12 and the Xa 4000 system power amplifier,
whether it is connected directly or looped through the FX 20
subwoofer.
CONNECTION PANEL
FLYING RAILS
HF COMPONENTS
If the power amp is driving
the FX 12 as a single
cabinet (e.g. for high quality
speech applications) using
standard pin-assignments,
all you need do is move the
sliding switch from “System“
(pins 2+/2-) to “Normal”
(pins 1+/1-) and the pins at
the socket will be correctly
configured.
The Acra flying rails provided as
standard, combined with the
CSST flying wires available as
accessories, allow the FX 12 to
be flown securely in the truss.
Various detents are provided, so
that exactly the right degree of tilt
can be obtained. Multiple cabinets can be connected using
CSSM flying wires equipped with
double studs on each side.
The CDH 8040-14 80° x 40° Constant-Q high
frequency horn is equipped with a ND 6-8
Neodymium driver reproducing the frequency
range above 1 kHz and is mounted coaxially
in the Conical Waveguide midrange horn.
To achieve the highest possible sound pressure levels, the FX 20
is conceived as a planar waveguide bass horn and armed
with an EVX 180B 18“ woofer with a high power-handling
capacity. The frequency range from 30 Hz to 150 Hz is reproduced with a maximum sound pressure level of 132 dB/1m.
Two of these planar waveguide subwoofers deliver up to 138
dB/1m per side and provide an extremely dry and deep bass
foundation for the Xa-2 system.
The 18” woofer, like the top, is afforded precise protection
against thermal overload by a fully electronic voice-coil tracking
system and even extreme power peaks are reproduced
precisely and powerfully without any dynamic loss.
The enclosure is constructed from multi-ply 15mm poplar plywood and is covered with an extremely hard-wearing needle
felt. Two sub-woofers achieve a stacked height of 180 cm,
permitting the overhead mounting of the FX 12 tops. The
same 4-pin Speakon connectors are used for the subwoofers as the tops.
The sub-signal delivered by the system power amplifier
reaches the sub-woofer via pins 1+/1- and the midrange/HF
signal is looped through to the tops on pins 2+/2-. Four
generously dimensioned rubber feet on both the bottom and
sides are provided to accommodate different set-up configurations and ensure high stability when stacking. In all, six
handles and four robust rollers on the rear permit easy
handling and safe transport.
HANDLES AND ROLLERS
THREADED ADAPTER
On the rear of both the FX
12 and the FX 20, you will
find four heavy-duty rollers.
Two handles on the tops and
six in all on the sub-woofers
facilitate transportation and
ensure safe handling when
stacking the cabinets.
Additional full-range
cabinets for front- or
side-fills or smaller
tops can be aimed and
securely mounted on
top of the FX 20 to
save space using the optional PCL 880 and
PCL 1500 threaded poles.
SUB COMPONENTS
The Planar Waveguide Basshorn FX 20
is armed with an Electro-Voice heavy-duty
EVX 180 B 18“ woofer.
The system power amplifier, the Xa 4000, is
designed as a two-way power amplifier (SUB-TOP)
and can be set up in a side-oriented configuration —
for short cable runs to the cabinets — or mounted
with similar devices in the rack. Employing Class H
technology, the 2U system power amplifiers boasts a
state-of-the-art switching power supply and weighs a
mere 8.25 kg. The output power is 1100 W in the
SUB channel and 900 W in the TOP channel, in each
case into 4 ohms, however up to three tops and/or
three sub-woofers can be driven with extreme reliability and economy. All the necessary signal processing — including equalization, LPN filter, lo-cut filter
and an active crossover at 140 Hz with an 18
dB/octave slope in a modified Butterworth configuration — is on board, as well as separate level controls
on the front for the SUB and TOP to allow individual
tailoring of the output to the venue or style of music.
The loudspeaker connection is provided by a 4-pin
Speakon system socket with pins 1+/1- feeding the
SUB and pins 2+/2- the TOP in addition to the 4-pin
system wiring. Two additional output sockets with
‘standard’ wiring on pins 1+/1- permit full-range
enclosures for side-fill or front-fill applications to be
driven from the TOP-OUT as well as central bass
speaker configurations.
The basic Xa-2 setup with two additional FX 20 sub-woofers for mobile DJ
events. Subs are arrayed horizontally for
a homogeneous near field and powerful
targeted bass reproduction in the far
field.
The Xa-2 with only two sub-woofers but
two additional FX 12 tops being flown.
For high-quality speech reproduction or
musical genres in which the attainment
of maximum sound pressure levels in
the LF range is not a high priority.

Maximum configuration driven by an Xa
4000 system power amplifier with three
subs and two tops per side for typical
Top 40 events and venues in big city
halls or medium-sized open air concerts. For very big events, where throws
in excess of 40m are required, a complete Xa-2 system per side can be used
without any problems.
STACKED
FOR LONG
DISTANCE
By using the FG 600 flying grid, which is available
as an optional accessory, FX12 tops (and other
600 mm wide cabinets like ‘Cobra’) can be flown
safely and quickly in the truss – or else mounted
on “genies” without any problems. With the SE
600 retractable rigging strap extension and a rigging strap, the whole wing of tops can be aligned
easily.

World’s First
Compact Line-Array System
Pat. Pent.
english
COBRA-2 SYSTEM
The COBRA-2 SYSTEM is designed to provide high-quality sound reinforcement for events in small to medium-sized marquees or halls covering
distances up to 40 metres and areas in the region of 1,000 square metres.
The COBRA-2 SYSTEM produces a maximum SPL of 137 dB L + 137 dB R
in the medium- and high frequency ranges and up to 141 dB in the bass.
In its basic configuration, the COBRA-2 SYSTEM consists of four COBRA
TOP midrange/high-frequency enclosures, four COBRA SUB subwoofers, a
ready cabled and programmed 12 U amp rack, the CSR-12, as well as the
necessary 4-core loudspeaker cables and a 2.5° wedge set (comprising a
pair of wedges that can be placed at the front or back of the cabinets) to aim
the COBRA TOPs at the listening area. The coverage pattern of the
COBRA-2 SYSTEM is 120° in the horizontal plane and 15° in the vertical.
Up to six COBRA TOPs and six COBRA SUBs can be driven by the CSR12 AMP RACK without difficulty. To allow for expansion of the system, the
CSR-12 has room for an additional 3U power amplifier (sub extension,
separate front-/side-fill or monitor), which gets its current from the CP-44
connector panel.
The largest sensible configuration of the COBRA-2
SYSTEM consists of one COBRA-2 array per side
(four TOPs and 4-6 SUBs per side). For especially
powerful and penetrating bass reproduction, suitable
for a wide range of types of music and venue, COBRA
PWH bass horns can be integrated into the COBRA-2
SYSTEM.
Since doubling the number of COBRA TOP enclosures
halves their vertical radiation angle, special attention
must be paid to the way they are aligned – regardless
of whether they are flown or stacked.
A COBRA TOP has a coverage pattern of 120° x 30°
(horizontal and vertical). Two COBRA TOPs stacked
directly on top of one another have a coverage pattern
of 120° x 15° and four stacked cabinets, 120° x 7.5°.
With a ground stack, it is easy to aim the TOP cabinets
at the listening area by placing CSW-25 2.5° wedges
between the SUBs or the PWHs.
COBRA-4 SYSTEM
The active 4-way COBRA-4 SYSTEM is designed to project over distances of up to 80 metres in medium-sized marquees, halls and open-air venues and produces SPLs at the FOH
position, 30 metres from the stage, of 110 dB in the medium- and high-frequency ranges and
up to 120 dB in the bass — the values typically required by a Top Forty band.
Through the use of two COBRA-4 TOPs and a COBRA-4 FAR, optimal line-array performance can be achieved without time-consuming tinkering.
With the COBRA-4 SYSTEM, in the vicinity of the PA, the vertical coverage angle in the high
frequency range is particularly wide, to cover the areas directly in front of the stage.
To project over long distances, a COBRA-4 FAR, which has a
coverage pattern of 90° x 5° in the high frequency range, is
positioned at the top of the array. For the low frequency range
and the midrange, the same components are used as in the
COBRA-4 TOP, so the low and midrange line array continues in
an unbroken line.
In all, eight COBRA PWH bass horns are used to generate the
sound pressure levels and projection typically required by Top
Forty bands and these can be stacked or arrayed as dictated by
the architecture of the room.
The COBRA-4 SYSTEM is driven by two ready-cabled and programmed CSR-4 amp racks with a DSP 244 controller, two
L2400 power amplifiers and a CP-84 connector panel.
The illustration shows a medium-sized
COBRA-4 configuration for typical
medium-sized open-air events in a
city.
It consists of a COBRA-4 system and
additional PWH bass horns as well as
two line-arrays each consisting of four
flown COBRA-4 FAR and 1 - 2
COBRA-4 TOP cabinets. The lowest
of the COBRA-4 TOPs (nearfield) and
the COBRA-4 FAR adjacent have
each been tilted 5° downwards, whilst
the highest three COBRA-4 FARs
hang in a straight line. Using the adjuster-belt, the central axis of these
three COBRA-4 FARs is aimed at the
most distant third of the area to be
covered. For particularly wide (> 15m)
applications, it makes sense to place
additional COBRA-4 TOPs on top of
the stacked COBRA PWH bass array,
to cover the area directly in front of the
stage.
