Eighteen Sound 8NMB420 16 Ohm 8″ 280W Loudspeaker

Eighteen Sound 8NMB420 16 Ohm 8″ 280W Loudspeaker

Product description:

Eighteen Sound 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.
