Description: The 8NCX is a 8" / 1" coaxial transducer designed for use in compact reflex enclosures with a nominal dispersion of 100 degrees. The low profile, smooth curvilinear LF cone provides smooth response within its intended frequency range and water prove protective coating, allowing application in a wide range of environments. The state-of-the-art 51 mm (2 in) LF voice coil has Kapton former, which together with high temperature resistant resin ensure high reliability by high power. A double aluminium demodulating rings reduce distortion and inductance and improve transient response. The special cone made of cellulose with carbon fibers improves waterfall response.
The neodymium 1" exit compression driver adopted is our ND2545 model. The HF driver diaphragm assembly, using triple layer polyester dome this together with phasing plug improve linearity of frequency response in high end. Because of design with single magnet assembly the speaker has very light weight and compact size.

1. AES standard. Power is calculated on rated minimum impedance. Measurement is in 18 L box enclosure tuned 82 Hz using a 60-2000 Hz band limited pink noise test signal applied continuously for 2 hours.
2. Program power is defined as 3db greater than AES Power Capacity.
* Linear Mathematical Xmax is calculated as: (Hvc - Hg)/2 + Hg/4 where Hvc is the voice coil depth and Hg is the gap depth.
