The 8NM610 is a 8 inch neodymium high output midrange frequency transducer designed
around a cast aluminum sealed basket.
The design goal for this unit is to achieve an extremely high sound output and quality for direct
and mainly horn loaded applications such as line array configurations. The back cavity volume
has been optimized with attention to horn applications and also on the heat extraction because
it is a true powerful heatsink for all the encapsulated magnet structure.
An oversized external configuration neodymium magnet, considerably more efficient than
traditional under-pole magnet topology, have been used in order to provide high flux density
and excellent distortion control.
A flux stabilizing copper ring minimizes the overall harmonic and intermodulation distortion
The curvilinear cone, made with a high damping wood pulp, has been developed to achieve the
best possible linearity within its frequency range.
The 75mm (3 in) aluminum inside outside 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 motive
energy. This results in an extremely linear motor assembly.
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 8NM610 far more resistant to the corrosive effects of salts and oxidization.
