W400A-HR

Key features:
  • Hi-rigid and reduced inherent resonance HR diaphragm is employed. By using the radial papermaking technique and whizzy hybrid materials, HR diaphragm realizes low distortion, high durability, large internal-loss and fast propagation speed like a metal diaphragm. This unique-shaped diaphragm offers smooth frequency response and superior low frequencyreproduction that the conventional cone diaphragm has never achieved.
  • Newly developed zincky die-cast frame based on the strength analysis by the fineelement method.
  • Stronger magnetic circuit using 3,100g alnico magnet is equipped for higher input durability and larger amplitude driving.
  •  Oval mounting hole can be adjusted between ø370 - ø375mm. W400A-HR has the compatibility with not only FOSTEX old 15” drivers but some famous woofers’ replacements.
  • UDR tangential surround & spider are equipped to realize the less anti-resonance and superior amplitude characteristic.
