Description
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 addition, a special coating
applied to both the top and back plates makes the 10NDA610 far more
resistant to the corrosive effects of salts and oxidization.
