Dayton Audio's ND91 aluminium cone full-range drivers are designed to deliver high output with low distortion. By using a voice coil diameter of 25mm and adding a copper alloy shorting ring, these drivers feature even lower distortion and deliver better bass impact and dynamic range—with peak Xmax up to 25 mm! This high-BL version further exploits the low distortion characteristics of the Neo-Balanced motor's optimized magnetic field, making the ND91 drivers an excellent choice for full-range point-source speaker enclosures, as well as extremely accurate, high resolution line arrays.
