Precision Transducers catalogue
Established in 1949, RCF prides itself on carrying out the design and production of its
own products.
We have always preferred to completely design and construct all our own components.
Many years dedicated to studying and building audio transducers have resulted in some
notable milestones.
There are many different ingredients that go into creating quality products and systems—
these include computer aided simulation software to assist the understanding of
transducer behaviour and the relationship of dynamics and transient response.
RCF utilises many state of the art software, however it is the vast technical and practical
experience that our Research and Engineering team posseses that ensures the quality of
our products, thus placing RCF as the market leaders in transducer development.
RCF The Transducer Innovators
The RCF loudspeaker line incorporates a vast range of transducers covering the entire
audio spectrum. We design our transducers to optimise the relationship between the
purity of sound, combining the absence of distortion and the ability to withstand high
power levels over a long period of time.
RCF develops advanced transducer technology including the application of high-tech
materials such as Neodymium, Carbon Fibre, Pure Titanium, Kevlar, Kapton and Mylar
hybrids.
With over 60 years of design and manufacturing experience in the market, RCF has been
instrumental in technological inventions such as: carbon fibre cone moulding, double
silicon spiders, inside/outside voice coil windings to edge wound voice
coil manufacturing and pure titanium diaphragm forming. Our latest developments have
resulted in designing state of the art neodymium magnetic circuits, radically new voice coil
ventilation systems and ground breaking direct drive voice coil assemblies.
1
POWER HANDLING
At the core of RCF’s new transducer designs, significant amounts of time and resources were spent in terms of material
science, design topology research and power testing in order to develop products with high structural strength, optimal
thermal characteristics and the best possible power handling. RCF Precision engineers have developed a composite
polyimide-imide former material capable of withstanding peak temperatures in excess of 380°C, well beyond the thermal
requirements of modern professional audio systems.
By combining this material with special adhesives, our inside-outside voice coil technology, dual silicone spiders, dual
forced hyperventilation and cones based on a special fibre doping and treatment, the new RCF family of products
features the industry’s most robust and reliable transducers.
NEW FERRITE MATERIAL: HIGH
POWER, LOW WEIGHT MAGNETIC
CIRCUIT DESIGNS
RCF Precision engineers have developed a new ferrite magnet capable
of delivering higher flux in a new, minimum weight design. Thanks to
this new technology, all new RCF Precision ferrite products present the
minimum weight for comparable performances. New specific magnet
sizes and moulds have been developed to optimise the new design
performances. RCF Precision set out to develop a magnetic circuit topology
capable of delivering the highest, balanced level of performance in three
specific areas: maintenance of a consistent, high integrity magnetic flux
gap, distortion lowering design techniques and efficient integration of
the magnetic circuit in a minimum weight design. The T-pole design is
optimised to generate the minimum amount of flux modulation in the
magnetic assembly during typical voice coil movement within the gap.
DUAL FORCED HYPERVENTING
SYSTEMS
In our complex cooling designs individual components come
together to create an ideal ventilation system.
Commencing with the design of the basket, RCF Precision has
focused on providing finned cooling channels while optimising
the surface area available in order for the front magnetic plate
to dissipate heat efficiently. When assembled and placed on
the basket, the front plate, ceramic core and the rear plate form
part of the ventilation system that is highlighted by cooling slots
precision machined through all three components. RCF Precision’s
unique double silicone sealed spider design functions as an air
pump expelling hot air and drawing in cool air every time the cone
assembly moves. This system provides cooler operating conditions
and optimal power compression.
The perfect balance of noise control and quantity of the air venting
the inner side of the voice coil is guarantee from a diffractor placed
at the centre of the pole piece.
2
DIAPHRAGM ASSEMBLY
The new RCF Precision features several state of the art technologies. The diaphragm and
suspension are precision formed from ultra thin pure titanium, Kapton or Mylar. The suspension
is based on an innovative design that drastically reduces distortion eliminating resonance points
and assists in controlling suspension breakup modes. RCF has developed an oxygen free process
of moulding pure titanium ultra thin films in high quality, finely controlled shaped diaphragms.
Our process offers superior sonic quality, extended to the highest audible frequencies which
guarantee consistent power handling and reliability.
DIRECT DRIVE VOICE COIL ASSEMBLY
The top of the former is bent and bonded directly to the edge of the titanium diaphragm resulting in a Direct Drive
configuration. Direct Drive guarantees optimal transfer of energy between the voice coil and the dome assembly,
providing smoother, extended frequency response beyond 10 KHz, reducing break up modes and lowering
distortion.
This assembly delivers high power handling along with excellent mechanical and thermal properties that make RCF
neodymium compression drivers robust and reliable.
MAGNETIC CIRCUITS
RCF Precision Neodymium magnetic circuit designs provide even higher magnetic field strength
in the voice coil gap than standard ceramic assemblies while dramatically lowering the overall
weight of the device. Neodymium rare earth material also provides higher levels of force (BL)
that increase control of the dome assembly’s moving mass. This leads to higher efficiency, better
transient response and diminishes high frequency distortion modes.
RCF’s new ferrite magnetic circuit design is optimised to offer the highest possible magnetic
field strength achievable in the voice coil gap, providing the required force to precisely control
the dome assembly’s moving mass.
A thin copper ring is precision pressed onto the pole piece in order to modify and lower the
inductance characteristics of the magnetic circuit and voice coil, thus providing a controlled
extension of the acoustic frequency response. RCF Precision has provided cooling fins on the
rear of the aluminium diaphragm assembly cover that creates a heat dissipating surface area for
the driver’s magnetic circuit. This assists in lowering circuit temperature, improving the driver’s
power compression characteristics and increasing output.
PHASE PLUGS
The ND950 features a 4-slot, optimised geometry, aluminium phase plug design. Extensive
computer assisted mathematical modelling and testing has resulted in a phase plug geometry
that provides balanced acoustic performance by controlling and lowering air distortion and
maximizing output. This permits the use of a lower phase plug slot compression ratio that
generates substantially lower distortion artefacts. The result is high output with smooth acoustic
frequency response and low harmonic distortion artefacts.
Our compression drivers features 3-slot, 2-slot and radial optimised geometry phase plug
designs. Extensive computer assisted mathematical modelling and testing has resulted in phase
plug geometries that provide balanced acoustic performance by controlling and lowering air
distortion.
3
INSIDE/OUTSIDE VOICE COILS
RCF has developed a unique voice coil, combining the advantages
of inside/outside technology with the superior quality of polyimideimide materials (wire resins and formers resins). The inside/outside
coil offers many advantages: the dissipation surface is doubled; the
adhesion area to the Former is doubled; during thermal expansion
the Former is squeezed between inside and outside layers offering
the best mechanical resistance. Our inside/outside formers are made
from polyimide-imide fibreglass and the area between the coil and
the cone is a triple layer of Nomex - Fibreglass - Nomex for maximum
stiffness and accurate sound transfer.
DUAL SILICONE
SPIDERS
RCF’s original invention of the
dual silicone sealed spider design
offers many advantages: the two
spiders offer double resistance
to fatigue; the silicone between
the cloth layers, being a very high
memory material, provides the
best shape stability to the spiders;
the system, being sealed, functions
as an air pump expelling hot air
and drawing in cool air every time
the cone assembly moves.
4
RCF dual silicon sealed spider design provides
our transducers with cooler operating conditions
and optimised power compression.
MECHANICAL DESIGN
RCF Precision has also invested countless hours addressing mechanical design issues. Connection of lead
wires is improved through the design of a specific spoke capable of providing a safe and larger excursion in
a noiseless and safe side connection. Baskets are designed to provide the maximum strength, the lightest
weight, while minimizing overall diameter and maximizing cone piston diameter.
EDGEWOUND COILS
Edge-wound flat wire voice coils are a
hallmark of advanced manufacturing.
RCF produces in-house all the flat wire
voice coils used in its compression
drivers. To guarantee the ultimate level of
performance and reliability, maximum care
in material selection and process design
is combined with extensive use of quality
control and power testing procedures.
Each driver is thoroughly tested for
frequency response, impedance and
distortion with DSP enabled digital testing
equipment. The result is
a robust device capable of withstanding
the rigors of modern loudspeaker system
applications.

LOW FREQUENCY
NEODYMIUM
TRANSDUCERS
For decades RCF professional woofers have represented the ultimate
performance, the highest power handling and the most advanced
technology.
Thanks to high energy magnetic designs, complex cooling systems and
specifically developed new technologies, our neodymium transducers
place themselves at the same, unsurpassed level.
6
SEALED MIDRANGE TRANSDUCERS
RCF has developed two exceptional, sealed, midrange neodymium designs. This innovative solution offer many advantages
compared to traditional midranges designs:
- thanks to a massive neodymium magnetic circuit, sensitivity is up to 4 dB higher than traditional designs;
- the optimally tuned rear chamber is sealed and doesn’t require the typical back wooden chamber;
- the aluminum basket, in direct contact to the magnetic circuit, provides the best cooling ever found in a midrange
transducer.
INSIDE/OUTSIDE VOICE COILS
RCF has developed a unique voice coil, combining the advantages of inside/outside technology to the superior quality of
polyimide-imide materials (wire resins and formers resins).
The inside/outside coil offers many advantages:
- the dissipation surface is doubled;
- the adhesion area to the Former is doubled;
- during thermal expansion the Former is squeezed between inside and outside layers offering the best mechanical
resistance.
Our inside/outside formers are made from polyimide-imide fibreglass and the area between the coil and the cone is a triple
layer of Nomex - fibreglass - Nomex for maximum stiffness and accurate sound transfer.
COMPLEX COOLING SYSTEMS
In our complex cooling designs individual components come together to create an ideal ventilation system. Commencing
with the design of the basket, RCF has focused on providing finned cooling channels while optimising the surface area
available to the front magnetic plate to dissipate heat efficiently.
The dust cap and the sealed spiders function as an air pump expelling hot air and drawing in cool air every time the cone
assembly moves. Many openings are situated directly on the transducer’s side and on the rear plate.

LOW FREQUENCY
TRANSDUCERS
RCF was the first manufacturer introducing many of the innovations that
are now recognised standard in professional transducers, pioneering
new solutions, from inside-outside voice coils to dual spider silicon
damped designs.
Our range, including several industry milestones, is able to provide
innovative tools and solutions for the most demanding speaker
manufacturers.
46
MAGNETIC CIRCUITS DESIGNS
RCF R&D set out to develop magnetic circuits capable of delivering the highest, balanced level of performance in three
specific areas; maintenance of a consistent, high integrity magnetic flux, distortion lowering design techniques and efficient
integration of the magnetic circuit design within the overall design of the loudspeaker cooling system. Our transducers
features a fully optimized magnetic circuit highlighted by a flux maximizing design and a rear plate that provides the
lightest possible weight and highest flux efficiency. The design is optimized to generate the minimum amount of flux
modulation in the magnetic assembly during typical voice coil movement within the gap.
DUAL SILICON SPIDERS
RCF original dual silicone sealed spider design offers many advantages:
- the two spiders offers double resistance to fatigue;
- the silicon between the cloth layers, being a very high memory material, provides the best shape stability to the spiders;
- the system, being sealed, functions as an air pump expelling hot air and drawing in cool air every time the cone assembly
moves.
RCF dual silicon sealed spider design provides to our transducers cooler operating conditions and optimised power
compression.
PROGRESSIVE SPACED DEMODULATION RINGS
Our top level low frequency transducers feature RCF unique spaced gap demodulation technology designed to dramatically
lower distortion artifacts within the loudspeaker’s operating frequency band. This technology assists in progressively braking
the voice coil as it reaches its maximum excursion point. This braking effect provides a much quieter, smoother transition for
the moving mass as it reaches its maximum excursion limits.

HIGH FREQUENCY
NEODYMIUM
TRANSDUCERS
Every detail is under our control, from titanium forming and voice coil
winding to phase plugs machining and final assembly.
Lightweight and powerful, our neodymium drivers are a reference in
performance and reliability.
DIRECT DRIVE VOICE COIL ASSEMBLIES
The top of the former is bent and bonded directly to the edge of the titanium diaphragm resulting in a Direct Drive
configuration.
Direct Drive guarantees optimal transfer of energy between the voice coil and the dome assembly, providing smoother,
extended frequency response beyond 10 KHz, reducing break up modes and lowering distortion. This assembly delivers high
power handling along with excellent mechanical and thermal properties that make RCF neodymium compression drivers
robust and reliable.
DIAPHRAGM ASSEMBLIES
Diaphragms and suspensions are precision formed from ultra thin pure titanium. Suspensions are based on an innovative
design using progressive parabolic semi circles. The sections of the suspension offer a consistent suspension modulus
with a variable, altering profile. This drastically reduces distortion eliminating resonance points and assists in controlling
suspension break-up modes. The rear magnetic plate where the diaphragm assembly is located, possesses specially designed
CNC machined ventilation slots that eliminate standing waves, turbulence and distortion created by the movement of the
suspension. At the point where the titanium suspension is bonded to the assembly ring, a special dampening adhesive has
been applied in order to further reduce and eliminate distortion creating resonances. The diaphragm assembly has been
designed with easy field service in mind as it can be removed and replaced within minutes.
NEODYMIUM MAGNETIC CIRCUITS
Neodymium magnetic circuit designs provide even higher magnetic field strength in the voice coil gap than standard ceramic
assemblies while dramatically lowering the overall weight of the device. Neodymium rare earth material also provides higher
levels of force (BL) that increase control of the dome assembly’s moving mass. This leads to higher efficiency, better transient
response and diminishes high frequency distortion modes. A thin copper ring is precision pressed on to the pole piece
in order to modify and lower the inductance characteristics of the magnetic circuit and voice coil providing a controlled
extension of the acoustic frequency response. RCF has provided cooling fins on the rear of the aluminum diaphragm
assembly cover that creates a heat dissipating surface area for the driver’s magnetic circuit. This assists in lowering circuit
temperature, improving the driver’s power compression characteristics and increasing output. Specific attention has been
paid to magnetic circuit polarization for optimum thermal immunity.

PURE TITANIUM DIAPHRAGMS
RCF has developed an oxygen free process of moulding pure titanium ultra thin films in high quality, finely controlled
shaped diaphragms. Our process offers superior sonic quality, extended to the highest audible frequencies which guarantee
consistent power handling and reliability.
EDGE-WOUND COILS TECHNOLOGY
Edge-wound “flat wire” voice coils are a hallmark of advanced manufacturing. RCF internally produces all the flat wire voice
coils used in compression drivers. To guarantee the ultimate level of performance and reliability, maximum care in material
selection and process design is combined to extensive use of quality control and power testing procedures.
Each driver is thoroughly tested for frequency response, impedance and distortion with DSP enabled digital testing
equipment. The result is a robust device capable of withstanding the rigors of modern loudspeaker system applications.
PHASE PLUGS
Our compression drivers features 3-slot, 2-slot and radial optimized geometry phase plug designs. Extensive computer
assisted mathematical modelling and testing has resulted in phase plug geometries that provide balanced acoustic
performance by controlling and lowering air distortion and maximizing output. The use of a lower slot compression ratio
results in higher acoustic output with smoother frequency response and lower harmonic distortion.

COAXIAL
TRANSDUCERS
The power of Neodymium, the integration of two magnetic circuits in
one, the precision of assembly.
In all RCF coaxial transducers we take care of every single detail;
magnetic circuits, horns, cones and basket designs are all conceived to
guarantee the perfect match. RCF coaxial “point source” transducers
deliver the full frequency range in correct phase alignment, resulting in a
smoother frequency response, precise polar pattern and perfect clarity.
134
HIGH NEODYMIUM FLUX, BEST CONTROL
Often a big drawback in coaxial designs is the lack of magnetic force due to the fact that woofer and compression driver are
sharing the same magnet. All RCF Coaxial designs takes advantage of large sized magnetic rings that guarantee for both
the transducers the same flux in the gap that they have in stadard, single magnetic circuit, applications.
HIPER VENTED DESIGNS
In a coaxial design the thermal dissipation required is higher than in conventional designs: woofer and compression driver
are both dissipating heat in the same structure. New basket designs and new ventilation system for magnet plates, together
with inside-outside voice coils and high temperature material guarantee the perfect behaviour of the transducer in the most
stressful conditions.
PHASE ALIGNED CONICAL HORNS
The tweeter/cone interaction is improved on RCF coaxial speaker by the mean of large-sized, phase aligned, conical horns.
RCF horns are specifically designed to improve the transducers phase alignment, to offer a smooth crossover transition,
to guarantee a perfect constant and conical directivity to the compression driver. The presence of the horn avoid any
intermodulation distortion caused from the low frequency excursion of the woofer cone.

The CX15N351 is designed to provide an excellent frequency response linearity
with very low distortion. This coaxial use a strongest unique neodymium magnetic

mid-bass section use a 3,5” voice coil design provides a very high power handling,
especially recommended in comparison to a standard 3” voice coil, demodulation
ring get a fastest time response and lower distortion .The compression driver use a
2.5” diaphragm with a 1.4” throat featuring several state of the art technologies. The
diaphragm and suspension are formed from 0.05mm thick pure titanium.
