The 8NM610 is a 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 have 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. This is further guaranteed by a flux stabilizing ring with the function of minimizing the overall harmonic and intermodulation distortion figure.
The curvilinear cone, made with a high damping wood pulp, has been designed to achieve the best possible linearity within its frequency range.
The state-of-the-art 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.

The 8NMB420 neodymium transducer has been developed in response to a specific market requirement for a 8� midbass driver that combines excellent linearity with good efficiency and high power handling capabilities.
8NMB420 is primarily intended for use as a midbass driver in compact 2-way or multiway reflex enclosures comprising line arrays. The parameters had been chosen to offer significant low frequency output in vented enclosure with size starting from 20 lit. with a tuning frequency around 60Hz. The low pass filter might be positioned as high as 2000-2500Hz. Multiple 8NMB420 units might be used: the compact size reflects in the capability to have precise attack time. This characteristic makes it the ideal choice for stage monitoring and bass guitar amplification.
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, as a consequence, at the upper professional level with best power to weight ratio.
The exclusive dedicated triple shape surround design offers enhanced linear travel and control, in order to reproduce precisely low frequency.
The curvilinear paper cone is formed using a unique wood pulp composition designed to achieve the best possible rigidity and stiffness.
The 50mm� state-of-the-art, aluminum wire voice coil employs Interleaved Sandwich Voice coil (ISV) technology. It is composed by a high strength fiberglass former used to carry windings on both the outer and inner surfaces to achieve a mass balanced coil. This results in an extremely linear motor assembly which, in conjunction with the highly advanced design of the magnetic structure, provides a high force factor or BL. The voice coil is cooled incorporating airways between the chassis back plate and the magnet faceplate so that heated air is channeled away from the voice coil and gap and dissipated by the chassis basket.
Thanks to the increasing use during outdoor audio events, the ability to perform in humid environments is a key feature of the 8NMB420. This is achieved trough an exclusively developed cone treatment which render the cone humidity repellent while does not increase the total moving speaker mass.

The 8M400 is a high power, high output, 8� midrange for high level professional use. The excellent sound quality has been achieved as a result of extensive research on mid frequencies intelligibility. The 8M400 has been designed for use as a midrange in both horn and direct radiation, closer or reflex enclosures, as small as 3 lt.
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 is a humidity repellent and also dampens the bell mode resonance significantly.
The 51 mm (2�) voice coil assembly is wound on a strong fiberglas former to improve force transmission and power handling.
The powerful magnet assembly assures high flux concentration. The force factor and power handling are at an optimum level. The direct contact between the finned basket and the magnetic structure significantly improves thermal connection and heat dissipation, further increasing power handling and lowering power compression.
The copper shorting ring on the pole piece reduces inductance and improves transient response and phase control in the mid frequencies.

The 8MB400 transducer has been developed in response to a specific market requirement for a 8� midbass driver which combines excellent linearity with good efficiency and power handling capabilities. It is primarily intended for use as a midbass driver in compact 2-way reflex enclosures with a 1� compression driver or tweeter but as a result of its versatile characteristics, it can also be used in multiway systems.
The curvilinear, paper cone is formed using a unique wood pulp composition designed to achieve the best possible rigidity and stiffness. This is carried by a polycotton multiroll surround to provide increased excursion whilst controlling break up modes.
The 50 mm � state-of-the-art, aluminum wire voice coil employs the same technology fitted to our top-of-the-range models, i.e. our Interleaved Sandwich Voice coil (ISV) technology. It is composed of a high strength fiberglas former carrying windings on both the outer and inner surfaces to achieve a mass balanced coil. This results in an extremely linear motor assembly which, in conjunction with the highly advanced design of the magnetic structure, provides a high force factor or BL.
The voice coil is cooled by incorporating airways between the chassis back plate and the magnetic top plate to channel heated air away from the voice coil and gap and dissipate it.
In-house FEA CAD facilities have been used to optimise flux density and BL factor within the air gap.
Due to the increasing use of sound systems at outdoor events, the 8MB400�s ability to perform in humid environments is a key feature. This has been achieved using an exclusive cone treatment which renders the cone resistant to humidity.
