Fostex FW405N 15" Woofer
- Newly developed aluminum die-cast frame based on the strength analysis by the fine-element 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 lightweight & high stiffness diaphragm.
- Treated foam surround
- 3" voice coil diameter
