NDFEB 1-12"

NDFEB 1-12"

Fully designed and manufactured in house with a high strength neodymium motor and a custom-wound light-weight three inch four layer voice coil, the NDFEB-1 fulfills the needs of both the SPL competitor and sound quality enthusiast.


Utilizing 8 N52-grade magnets, the NDFEB-1 motor has the strength necessary to utilize every watt you throw at it, all while maintaining exceptional accuracy through our proprietary light-weight moving assembly. While this makes for an excellent combination, you can push the NDFEB-1 even further by adding on a Carbon Fiber cone, increasing efficiency and clarity even further while also adding a bit of visual flair.
