        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.

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

        Medium levels of THD, lots of excursion, quite a delicate cone (don't touch it at high excursion with your fingernail, you'll dent it). Overall a great woofer for a compact boombox or a decent option for bookshelf speaker, tho I'd like a lower THD level for a quality bookshelf.
