Key features:
  • Newly developed aluminum die-cast frame based on the strength analysis by the fineelement method.
  • Stronger magnetic circuit using ø200mm ferrite magnet is equipped for higher input durability and larger amplitude driving.
  • Oval mounting hole can be adjusted between ø370 - ø375mm. FW405N has the compatibility with not only FOSTEX old 15” drivers but some famous woofers’ replacements.
  • Hybrid cone paper, the porous super damping fiber + carbon fiber mixed into tree pulp basis material, is used to realize the light weight & high stiffness diaphragm.
