Eighteen Sound 8NMB420

The Eighteen Sound 8NMB420 speakerborn in response to a specific market request for an 8-inch medium-low transducer that combines excellent linearity, good efficiency and high power management capacity. 18Sound 8NMB420 sees its use as medium-low in compact multi-way reflex systems or used in line array systems. Its electroacoustic parameters offer an important reproduction of low frequencies in reflex boxes with volumes starting from 20 liters, with a tuning frequency around 60 Hz. In addition, several speakers can be coupled in the same cabinet: the compact dimensions translate into ability to have a very precise and well defined attack time. This feature (together with the wide variety of impedances available - 4,

Features

The extremely powerful neodymium magnet ensures high concentration of flux, low Power Compression and excellent heat exchange. The unique dual wave suspension design offers optimized control and linear travel, which results in precise reproduction of low frequencies. In addition, the paper cone was created using a unique wood pulp composition, designed to obtain the maximum possible rigidity and strength.

In addition, the 50 mm aluminum moving coil uses ISV - Interleaved Sandwich Voice Coil construction technology . The glass fiber former supports the windings both on its external and internal surface, to obtain a coil with balanced mass. This results in an extremely linear motor unit which, in combination with the advanced design of the magnetic structure, provides a high force factor. In addition, the moving coil cools through openings between the rear of the basket and the front polar plate. In this way the exhausted air is conveyed away from the moving coil and the air gap, and dissipated by the basket.
