NDT995 Driver
The 4-inch pure titanium dome NDT995 compression driver focuses on maximizing linearity, precision and long-term reliability. It is mainly suitable for professional line arrays and point source applications. Its motor structure features a high-flux density neodymium magnet assembly with a copper demodulation ring to reduce harmonic and intermodulation distortion. The 4" class-leading design utilizes a Kapton former, inside-outside ultralight edge wound aluminum wire and a 4-slot phase plug to deliver minimum distortion across its operating bandwidth. The high sensitivity at 110 dB, 280 Watts continuous power handling at 8 ohms, and very low recommended crossover point from 650 Hz make it ideal for integration with waveguides in two-way high-powered systems.
