By increasing the original ND90’s voice coil diameter from 3/4″ to 1″ and adding a copper alloy shorting ring, the ND91-4 features even lower distortion and delivers 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.Show more Show less
