The 10M600 is a top performance 10" ferrite midrange driver which offers
high power handling capability with exceptional sensitivity over the
middle frequency band. It is suitable for either direct radiating or
horn loaded applications as part of a 3 or 4-way auditorium, touring, or
outdoor festival sound system. It is the result of an intensive
development program which aimed to produce the best 10" ferrite midrange
driver available. The smooth curvilinear paper cone has a special high
strength wood pulp composition and has been designed to achieve the
best possible linearity within the middle frequency range and to control
bell-mode resonances around the cone circumference. The cone is carried
by a double half-roll suspension composed of a material which is more
resistant to aging and fatigue than traditional materials, providing the
correct damping and excursion control. The 75 mm state-of-the-art
voice coil assembly incorporates a fine edge-wound aluminum wire
together with a strong fiberglas former to get the necessary force
factor, mass lightness and high power handling. The voice coil is
cooled using airways between the chassis back plate and the magnet face
plate, which allow heated air from the voice coil and gap to be
channeled away and dissipated by the chassis basket. This technology is
another product of 3D CAD resource application by our engineers. The
magnetic structure has also been optimized using our in-house FEA CAD
resource which has maximized the flux density in the voice coil gap. A
special treatment is applied to both the top and back plates making them
more resistant to the corrosive effects of salts and oxidation. This
treatment is more effective than any other treatment in use today.

The 10MB600 mid-bass transducer represents a development of the 10M600
midrange, combining excellent linearity with high efficiency and high
power handling capabilities. The 10MB600 is primarily intended for use
as a midbass driver in extremely compact 2-way reflex enclosures between
10 and 40 lt. Its curvilinear paper cone is formed using a special high
strength wood pulp, designed to achieve the best possible rigidity and
stiffness. An exclusive treatment is also applied to the cone to
increase its water repellent properties. The 75 mm state-of-the-art
voice coil is similar to those fitted to our top-of-the-range 18" and
15" models but it is wound with aluminum wire. The coil also employs our
Interleaved Sandwich Voice coil (ISV) technology. A high strength
fiberglas former carries windings on both the outer and inner surfaces
to achieve a mass balanced coil, resulting in an extremely linear motor
assembly with a reduced tendency for eccentric behavior when driven

The 10NDA610 is a high power, very high output, state-of-the-art
midrange transducer for high quality professional use. The high level of
sound reproduction is achieved thanks to extensive research by Eighteen
Sound engineers, which focused on implementing mid frequencies
intelligibility. The 10NDA610 is ideally used as a midrange in both
horn and direct radiation, closed or reflex enclosures, as small as 4
liters. The 10NDA610 incorporates an Active Impedance Control (A.I.C.)
consisting of an additional coil fixed on the pole piece and connected
in parallel to the moving coil. The magnetic field generated by this
coil has the following effects: 1) Impedance linearization 2) Acoustic
and electric phase linearization 3) Significant increase of
sensitivity and total SPL 4) Total harmonic distortion reduction 5)
Constant power transfer The A.I.C. offers substantial advantages to the
sound quality by not absorbing the moving coil's electromagnetic
energy. The extremely powerful external neodymium magnet assembly
assures high flux concentration, low power compression and excellent
heat exchange. The levels of force factor and power handling are
consequently at a top professional level, with the best power to weight
ratio on the market today. The curvilinear cone, made with a high
damping wood pulp, has been designed to achieve the best possible
linearity within its frequency range. The in-house developed cone
treatment acts as humidity repellent and significantly dampens bell mode
resonances. The 75mm edge-wound voice coil assembly is wound on a
strong fiberglas former to improve force transmission and power
handling. A proprietary humidity-block cone treatment makes the
transducer suitable for outdoor use in adverse weather conditions. In

industry standard in 12" (300 mm) 4" voice coil high performance
transducers, already accomplished by the 15LW1400 and 18LW1400

suited for very high loading cabinets, such as bandpass, horn loaded or
compact reflex configurations. In its reflex configuration, 12LW1400 can
be used in extremely compact enclosures (30 - 60 lt), making it the
ideal choice for touring applications, sound reinforcement or fixed
installations, including indoor and outdoor concert reinforcement
systems. Maximum strength, smooth response and high displacement piston
motion are obtained using Double Silicon Spider technology (DSS) and a
large excursion surround. A special formulation cone material has been
used to enable it to withstand high loading and high power peaks. The
suspension system has been designed to give symmetric large signal
behavior across the whole working range, providing low harmonic
distortion at different excitation levels. An inside outside aluminum
voice coil, based on Interleaved Sandwich Voice coil (ISV) provides high
levels of thermal stability and durability. The ISV technology is based
on a high strength fiberglas former with half the coil wound on the
outside and half on the inside ensuring uniform thermal dissipation on
both sides. It is bonded together using unique high temperature resin
adhesive to achieve a balanced and solid linear motor unit. Double
Demodulation Rings (DDR) technology dramatically reduces the
intermodulation and harmonic distortion whilst improving the transient

possible results with today's available materials in terms of clean and
undistorted LF reproduction at a ultra high SPL, with the lowest
possible power compression figure. Its curvilinear paper cone made from a
special high strength wood pulp, has been designed to achieve the best
possible linearity within its intended frequency range and to control
bell-mode resonances around the cone circumference. The cone is carried
by a triple roll suspension formed of a linen-like material, which is
more resistant to aging and fatigue than traditional materials. The 65
mm (2.5 in) diameter state-of-the-art voice coil is made with edgewound
aluminum wire winded over a high strength fiberglas former. This results
in an extremely linear motor assembly with a reduced tendency for
eccentric behavior when driven hard. Voice coil cooling has been
achieved by incorporating airways between the chassis back plate and the
top plate of the magnet, allowing heated air from the voice coil and
gap to be channeled away and dissipated by the chassis basket. Special
attention was given to the optimization of air flow into the gap without
introducing audible noise. A special low-density material air
diffractor placed into the heatsink acts as a cooling system, increasing
the power handling capability and lowering the power compression
figure. The magnetic structure has been optimized using FEA CAD
resource, maximizing the flux density in the voice coil gap. Due to the
increasing use of high power audio systems at outdoor events or in
marine environments, the ability to perform properly under inclement
weather conditions is a key feature in Eighteen Sound philosophy. Hence,
an exclusive treatment has been applied to the cone giving it water
repellent properties. In addition, another special treatment has been
applied to the top and back plates making the transducer far more
resistant to the corrosive effects of salts and oxidization.DATENBLATT

curvilinear paper cone made from a special high strength wood pulp, has
been designed to achieve the best possible linearity within its intended
