SMALL AUDIENCES

Design:
Redcatt engineers have developed REDCATT branded transduc-
ers utilizing either neodymium or ferrite based magnetic circuits,
capable of delivering the highest level of performance, providing
a consistent, high integrity magnetic flux gaps, ultra low distor-
tion characteristics and high efficiency cooling designs.
The magnetic circuit designs are optimized to generate
the minimum amount of flux modulation, providing exceptional
stability.
REDCATT engineers use many modern Finite Element
Analysis and Modeling software tools to optimize the design. The
combination of computer aided technologies and years of design
experience in the field of audio products ensures our designs are
achieving and exceeding the set goals.
We have implement the latest 3D printing equipment
technologies to speed up our development time and shorten the
sample delivery times to our customers. In many cases we are
able to validate the fresh designs within hours after they have
been modeled in our computers.
Components:
REDCATT transducers always aim to use the best
available components, and the best available technology to
manufacture them. The level of precision, consistency and overall
quality achieved on all our components guaranties the highest
performance of our transducers. Our latest investments into the
state of the art CNC machining technologies is helping us to
achieve our quality goals without compromises.

VOICE COILS
Our in house wounded voice coils using inside/outside winding,
aluminum or copper ribbon wires. The extensive usage of Poly-
imide former materials, specialty winding adhesives and high
temperature wires allow us to push the power handling of the
transducers to the new heights while the voice coils are capable to
handle temperatures exceeding 350°C, beyond thermal require-
ment of modern audio systems. We pay great attention to all
related and necessary reliability testings of our voice coils.
SPIDERS
In many our woofer designs, REDCATT double or triple silicone
sealed spiders functioning as an air pump expelling the hot air
and drawing-in cool air every time the cone assembly moves.
Combined spider air-pump with highly efficient air flow magnet-
ic structure designs greatly reduces power compression.
CONES
The cones one and the dust cap are mostly made using an
advanced REDCATT pulps with carbon or glass fiber reinforce-
ment. The cones are also extensively treated to withstand harsh
environments and high humidity.
Metal parts in the speaker assembly are coated for extreme
weatherization protection.
Magnetic structure designs
Our engineers utilized the use of modern FEM software to
design, analyze and improve the magnetic circuits. Our designs
sport highly efficient based magnetic circuits capable of deliver-
ing the highest level of performance, providing a consistent, high
integrity magnetic flux gaps, ultra low distortion characteristic
and high efficiency cooling systems. The magnetic circuit designs
are optimized to generate the minimum amount of flux modula-
tion, providing exceptional stability.

ADHESIVES
REDCATT uses the state of the art adhesives in all assembly
steps. REDCATT unique, precise adhesives dispensing and
curing, combined with six-sigma quality monitoring and extra
care in storing and handling all adhesives, further improves the
product consistency and reliability. We pay lot of attention to the
details when it comes to adhesives. Our development and manu-
facturing processes were designed to fully support our vision for
how the modern transducers should be built.
Reliability testing
It is our mission to design and produce transducers
that are not only the best performing and consistent drivers
around, but we also pay great attention to the reliability testing
and longevity of our transducers. Our reliability testing lab is well
equipped to take the tested transducer to the limits in a con-
trolled and repeatable way. We can set the weather environment
from -40 to 150 °C with added humidity up to 99% RH. UV-A
and UV-B tests are also part of our reliability test cycles to accel-
erate the aging of the parts.
Implemented Klippel power testing equipment ensures
the driver is tested using the standardized AES power test proce-
dures, while all important parameters are monitored trough the
test cycle.

The 30FF is a high efficiency, (86dB 1watt / 1 meter) 3-inch
full range speaker with linear frequency response character-
istics and high power handling capability while generating
low harmonic distortion artifacts. The 30FF uses a lightweight
exponential pressed cone assembly along with a NBR single
roll geometry surround. The combination provides remarkable
strength, high efficiency and sustained output under extreme
conditions.
Power Handling
At the core of the 30FF is it’s voice coil technology featuring a
Kapton former material capable of withstanding peak tempera-
tures in excess of 240C, well beyond the thermal requirements
of modern professional audio systems and providing optimal
structural strength and thermal characteristics. Former strength
provides the ideal transfer of power between the voice coil and
the cone assembly and assists in reducing distortion artifacts.
By combining this material with state of the art adhesives and
our winding voice coil technology, the 30FF delivers very high
performance.

APPLICATION:
• Ideal for use in closed, vent port or passive-radiator applications
where the full range of frequency response is desired. 25FR is de-
signed to work well in multi-source array applications.
The 25FR is a high efficiency, (84dB 1watt / 1 meter)
2.5-inch full range speaker with extremely linear frequency re-
sponse characteristics and high power handling capability while
generating low harmonic distortion artifacts. The 35FR uses a

with a NBR single roll geometry surround. The combination pro-
vides remarkable strength, high efficiency and sustained output
under extreme conditions. Strong neodymium based magnetic
circuit generates very high and wide Bl in very small form factor.

REDCATT pulp, developed specifically for this application. All
“soft” parts are bonded together using state of the art UV based
high temperature adhesives. The speaker cone is also treated to
withstand harsh environments and high humidity. Metal parts
in the speaker assembly are coated for extreme weatherization
protection.

PRECISION HIGH FREQUENCY
TRANSDUCERS

High Frequency Transducers:
REDCATT HF transducers shows the level of precision and care
we are giving to these products. From the design, through the
incoming quality inspections and final assembly. All steps and
quality assurance processes were implemented with aim to pro-
vide our users with the best in class HF transducers.
Components:

DOMES
A key component of the HF assembly is the compression driver
or tweeter dome. We do form all HF domes in house with un-
beatable level of consistency. At REDCATT we consider this step
one and we have designed a unique dome forming process that
incorporates PLC controlled forming techniques to ensure all
aspects of the structure are precisely monitored. By using a pro-
grammable logic control (PLC) based system, we can incorporate
excessively detailed process parameters including pre-heating
and forming temperature controls that are within 0.5°C at each
stage of forming. The control and timing of the individual form-
ing steps are precisely established depending on the dome type
and material used then stored and recalled from memory at the
appropriate time.
We have developed unique coating technology for compression
driver domes. This unique process, was developed to greatly
improve the power handling capabilities. Further details can be
found on our web page www.redcatt.net.
In Process Dome Quality Assurance
Domes are randomly sampled after the forming process and
taken for dimensional and physical parameter measurements. We
have fully implemented precise laser based 3D scanning metrolo-
gy equipment, capable of detecting even the smallest variation in
the dome shape. We are fully capable of measuring dome shapes
with a 0.002mm level of precision.
VOICE COILS
Majority of our compression drivers use edge wound aluminum
wires. The extensive usage of Polyimide former materials, spe-
cialty adhesives and high temperature wires allow us to push the
power handling of the HF transducers to the new heights, while
the voice coils are capable to handle temperatures exceeding
350°C. In many designs, we use bent former assemblies to further
increase the bonding force between the voice coil and the dome
and improve the transient response of the HF unit.
PHASE PLUGS
It takes a significant amount of engineering to design a high
frequency device but making thousands of consistent parts based
on the original design is an order of magnitude more challenging.
The level of precision required to maintain good level of con-
sistency unit to unit, batch to batch, put lot of pressure on the
overall precision of all used components for high frequency
devices. Our transducer and quality engineers spent countless
hours to ensure all critical components maintain the required
level of precision and that the manufacturing process are capable
to deliver such parts. One of the most critical component is phase
plug. In many designs, we have chosen aluminum style phase

plugs, CNC machined from the ground up. The level of precision
on these phase plugs can be hardly matched by other manufac-
tures.
In other designs, plastic phase plugs are used. Special-
ty injection molding machinery and molding techniques were
selected to maintain the required precision level.
All parts are measured on advanced metrology equip-
ment. Modern metrology equipment as 3D CMM, scanning
lasers, profiling lasers or 2.5D vision systems are deployed in our
manufacturing process to control all tolerances with unprece-
dented precision.
ADHESIVES
REDCATT uses the state of the art adhesives in all assembly
steps. We have developed unique dispensing techniques and
adopted the best quality practices top ensure all dispensed adhe-
sives have great level of consistency and precision.
The majority of used adhesives are UV Cured Adhesives. UV
based glues require a proper and well controlled curing process
to ensure high, consistent bond strength. Our UV curing cham-
bers are providing high output ultra violet light which is precisely
projected and controlled. All assembled parts are cured under
multi-directional UV lights and are rotated in the chambers to
prevent shadowing.

The 25TF tweeter has incredibly linear frequency response char-
acteristics, high power handling capability while generating ultra
low harmonic distortion artifacts.
The 25TF Dome utilizes REDCATT in-house unique titanium
coating technology. Nitride is extremely hard ceramic material.
We deposit the nitride from both sides of the titanium dome. The
coated dome has dramatically improved flexural rigidity (aka
stiffness), compared to the pure titanium dome. The coating has
dramatic effect onto the distortion artifacts. The 3rd harmonic
distortion stays bellow 0.05% in the working range. Extended
high frequency response without major dome breakup modes
and improved transient response are the other positive effects of
REDCATT Titanium-Nitride Domes.
The 25TF has implemented FEM tuned rear resonant chamber.
The chamber is improving the tweeter behavior at low frequen-
cies and further lowering the harmonic distortion. All tweeter
parts are bonded together using state of the art high temperature
adhesives. Metal parts in the tweeter assembly are coated for
extreme weatherization protection.

extended frequency response and high power handling through
1.3inch exit throat. The suspension has designed and FEM
optimized venting features to lover the harmonic distortion. The
venting holes also improves the control over the dome move-
ments at low frequencies.
140NCD ultra compact design ensures the driver can
be used in enclosure designs where the space is very limited, such
as line array systems.
Magnetic Circuit Design
Redcatt has focused on designing an optimized neodymium
based magnetic circuit capable of delivering the highest level of
performance and value. The neodymium circuit is optimized to
generate the minimum amount of flux modulation providing
exceptional stability. This effort has resulted in a device that offers
uncompromised performance featuring high efficiency, excep-
tional transient response and controlled distortion characteris-
tics, all that in very compact size.
