•
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
ш370 - ш375mm. FW405N has the compat-
ibility with not only FOSTEX old 15” drivers
but some famous woofers’ replacements.
• Hybrid cone paper, the porous super damp-
ing fiber + carbon fiber mixed into tree pulp
basis material, is used to realize the light
weight & high stiffness diaphragm.
