The 8NMB250VCX is a 8" / 1" coaxial transducer with integrated HF horn, designed for use in compact reflex enclosures with high SPL and nominal dispersion of 60 degrees.
The low profile, smooth curvilinear LF cone together with HF horn increase the SPL in vocal range, which ensure big headroom. The cone with water prove protective coating, allowing application in a wide range of environments. The state-of-the-art 62 mm (2.5 in) LF voice coil has Glassfiber former, which together with high temperature resistant resin ensure high reliability by high power. The double aluminium demodulating rings reduce distortion and inductance and improve transient response.
The neodymium 1" exit compression driver adopted is our ND45 model. The HF driver diaphragm assembly, using triple layer polyester dome this together with phasing plug improve linearity of frequency response in high end.
