        Product details

        Dayton Audio ND91-4 3-1/2" Aluminum Cone Full-Range Driver 4 Ohm

         

        Dayton Audio's ND91 aluminum cone full-range drivers are the latest addition to the acclaimed ND Series high output/low distortion neodymium transducers. 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.

        A good upgrade on the 90-4. This has a larger voice coil, more driving force and lower resonance.

        Clear sound and long throw for bass. Works great in an LFS CTL3 nano bass cab!
