Description

The 12CX800 is a 12″ – 1.4″ coaxial transducer designed for use in
compact reflex enclosures and stage monitors as small as 30 lt, with a
nominal dispersion of 70 degrees.
The
state-of-the-art 75 mm (3 in) LF aluminum voice coil employs our
Interleaved Sandwich Voice coil (ISV) technology, in which a high
strength fiberglas former carries windings on both the outer and inner
surfaces to achieve a balanced coil with a uniform distribution of mass
and motion energy. This results in an extremely linear motor assembly.
The
low profile smooth curvilinear LF cone provides a smooth response
within its intended frequency range and maximum reliability under high
mechanical stress.
The neodymium 1.4″ exit HF compression driver
used is our ND1480 model. A further thermal power handling capacity has
been added thanks to high temperature ferrofluid added in the gap. The
HF driver diaphragm assembly uses a high strength high temperature
treated Nomex voice coil former joined directly to the titanium dome on
its upper bend edge. This assures extended frequency energy transfer
giving improved linearity and unparallel reliability when compared to a
usual straight former joint.
The HF motor structure utilizes a
precisely machined coherent phase plug with 3 circumferential slots and
a copper ring on the pole piece. This last feature reduces the
inductance figure of frequencies above 10 kHz, improving phase and
impedance linearisation.
A specific dedicated horn?s throat design
has also been chosen by Eigtheen Sound engineers, maximizing the cone?s
profile coupling.
With the increasing use of high power audio
systems at outdoor events, the ability to perform in adverse weather
conditions is another excellent feature of the 12CX800. This has been
achieved using exclusive cone and magnet plate treatment processes
which increase resistance to corrosion and make the cone water
repellent.
