Description: Authorized Dealer!Pair of Eighteen Sound 6NM410B 6" 180W Midrange Speaker Key Features100 dB SPL 1W / 1m average sensitivity44 mm (1 3/4 in) voice coil200 W AES power handlingExternal neodymium magnet assemblySingle Demodulating Ring (SDR) for lower distortionWeather protected cone and plates for outdoor usageImproved heat dissipation via Active Cooling SystemSpecially designed for line arrays and compact two way systemsDescriptionThe 6NMB420 is a 44mm voice coil 6.5 inch neodymium midbass transducer designed for mid low frequency reproduction in system designs where high intelligibility is required.When compared to our 6ND410 state-of-the-art midrange transducer, 6NMB420 offers a lower frequency resonance and a longer linear Xmax value. As a result the speaker shows an increased output around 250Hz, with a consequent slightly reduced output above 700Hz.It is suitable as mid-bass in line array systems or multiple way systems with high-pass crossover above 200 Hz and low-pass up to 3kHz; enclosure might be closed or vented with volume size starting from 2 lit.The speaker offers a superb linearity: distortion values are furtherly minimized by new enhanced design criterias, developed by Eighteen Sound engineers, taking the 6NMB420 to very high level of performance.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.A consistent heat transfer is guaranteed by the encapsulation of the magnetic structure in the interior of the basket, offering a largecontact space between the back plate and the dissipating structure.Particular efforts were dedicated to the surround shape and material design in order to minimize the resonances on mid range frequencies. The triple roll design offers a consistent damping to typical bell modes.The 44 mm voice coil is made of light-weight aluminum wire and assures linearity and high power handling.The ability to perform in humid environments is a key feature of the 6NMB420: this is achieved through a proprietary humidity repellent cone treatmentGeneral SpecificationsNominal Diameter152mm (6 in)Rated Impedance8 OhmAES Power200 WProgram Power260 WPeak Power500 WSensitivity100 dBFrequency Range200 - 7000 HzPower Compression at -10dB0,9 dBPower Compression at -3dB1,6 dBPower Compression at Full Power2,9 dBMax Recomm.
