      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.

      I was not able to find other driver quite like this one. Very linear with a great low-end. Suitable for very small boxes with a passive radiator. This + one of the ND tweeters + 2x ND90PR would make a great little bookshelves. Only thing I dislike is the ugliness when mounted from the front. They look much cleaner when mounted from the rear side of the baffle, but then you might get into problems with time allignment
