18 Sound ND1070 NEO Compression Driver Speaker

The (Eighteen) 18 Sound ND1070 1-inch exit high frequency compression driver has been designed for use in high quality two-way audio systems.
Equipped with Proprietary Phase Plug architecture, ND1070 shows high level manufacturing consistency and a smooth coherent wavefront at the horn entrance across the whole working frequency range. With its short openings and high flare rate value, this phase plug configuration assures low distortion and demonstrates remarkable improvements in mid-high frequency reproduction. The ND1070 diaphragm assembly is composed of a titanium dome sandwiched to a proprietary treated polyester suspension. This design maintains low resonance and lowers the minimum crossover point value to 1.6 kHz.
An edge-wound aluminum voice coil wound on proprietary treated Nomex completes the diaphragm assembly. Nomex shows a 30% higher value of tensile elongation at a working operative temperature (200°C) when compared to Kapton. This feature enables proper energy transfer control from the voice coil to the dome in real working conditions. Moreover, this proprietary former material is also suitable for use in high moisture content environments.
A copper ring on the pole piece reduces inductance above 10 kHz, improving phase and impedance linearization. By careful use of elementary pieces of neodymium magnets, Eighteen Sound engineers have developed a powerful neodymium magnet assembly capable of reaching 18KGauss in the gap within a compact and lightweight structure.
The custom designed O-ring creates a tight seal between the plate and the cover assuring air chamber loading. Excellent heat dissipation and thermal exchange are guaranteed by the direct contact between the magnetic structure and the aluminum cover which leads to a lower power compression value.
The ability to perform properly under inclement weather conditions is a key feature in Eighteen Sound philosophy. A special treatment has been applied to the magnet and the top and back plates of the magnetic structure making the driver more resistant to the corrosive effects of salts and oxidization. This treatment is more effective than any other treatment used by other manufacturers.

Designed & manufactured in Italy and provided exclusively on-line by Lean Business, this Eighteen Sound compression driver comes complete wth 2 years warranty.
