18 Sound 8NMB750 350watt 16ohm 8 " High Performance Mid Bass Speaker

93.6 dB SPL 1W-1m average sensitivity
700 W program power handling
75 mm (3 in) Interleaved sandwich voice coil
External Neodymium magnet assembly
Single Demodulating Ring (SDR) for lower distortion and maximum sound clarity
Copper ring for reduced distortion and increased output
Weather protected cone and coated plates
Suitable for high performance line array and compact two way systems

18 Sound’s 8NMB750 mid-bass neodymium transducer is a state-of-the-art 8-inch midbass driver that combines excellent linearity with high power handling capabilities (700 W) and reduced power compression.

The external neodymium magnet assembly assures high flux concentration and excellent heat exchange.

The 75mm (3 in) inside outside aluminum voice coil employs Interleaved Sandwich Voice coil (ISV) technology.

A sophisticated distortion reduction system has been implemented using a demodulating ring for flux modulation cancellation related to voice coil excursion, together with a copper ring for the reduction of intermodulation distortion. Both systems are linearizing the inductance in relation to the excursion as well as the current variation.

The cone is treated against extremely aggressive environment conditions.

The compact size makes the 8NMB750 an ideal choice for high performance line arrays and compact two-way systems.



Designed & manufatured in Italy and provided exclusively by Lean Business, this Eighteen Sound speaker comes complete wth 2 years warranty.
