Динамик НЧ FOSTEX W400A-HR. Инструкция на английском языке

W-series
W400A-HR
Features
• Hi-rigid and reduced inherent resonance HR
diaphragm is employed. By using the radial pa-
permaking technique and whizzy hybrid ma-
terials, HR diaphragm realizes low distortion,
high durability, large internal-loss and fast
propagation speed like a metal diaphragm. This
unique-shaped diaphragm offers smooth fre-
quency response and superior low frequency
reproduction that the conventional cone dia-
phragm has never achieved.
•Newly developed zincky die-cast frame
based on the strength analysis by the fine-
element 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
o370 - o375mm.  W400A-HR has the com-
patibility 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.
