TECHNOLOGY
Innovation, Integration, Intensity
INNOVATION - Our research and engineering department can
offer innovative projects with finite control of each detail, from
the loudspeaker voice coil wire to the highly efficient extended
dynamic amplifier topology. 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 amplifier operation and the relationship
of dynamics and transient response. RCF utilises over thirty state
of the art software packages to identify magnetic circuits, voice
coil dynamics, suspension linearity, horn dispersion simulation,
crossover filters, amplifier thermal behaviour and more.
INTEGRATION - RCF is one of the few loudspeakers manufacturers
worldwide who have the ability to completely design and
manufacture transducers, speaker systems and amplification and
control electronics. Our 60 plus years heritage in audio combined
with our state of the art R&D and manufacturing processes, allow
us to seamlessly integrate all the ingredients to design and build
the TT+ High Definition Touring and Theatre systems.
INTENSITY - The design philosophy for the TT+ Series is based
upon offering the sound engineer solutions and tools that are
ready to use. Key factors are the ability to sustain very high power
with highly efficient sound pressure levels. Intense sound levels
are created with extremely high definition and extended dynamic
range. Modern construction materials result in mechanical weight
ratios that are light for practical flying and portability.
Waves Structures
New horn designs for the entire line. Precision waveguides for the line arrays
midrange and compression drivers. Solid aluminium structures for compact
two-way systems.
Baltic birch plywood cabinets. High quality steel mechanical fittings. Aluminium
die cast handles. Powder coated grilles. Heavy duty polyurea or epoxy paint

THE BEST VOCAL
CLARITY FROM A
LARGE LINE ARRAY
The TTL55-A midrange transducer features a
unique “Impedance Control Coil” technology.
A secondary coil wound on the speaker
yoke and driven in opposite phase to the
primary coil has the function of cancelling
the primary coil inductance, increasing the
speaker sensitivity and reducing the speaker
distortion. A primary effect of this technology
is the improvement of the temporal
behaviour of the speaker, improving the
crossover transition from the midrange to the
compression drivers.
