FW-series
FW800HS
Features
• FW800HS is the large diameter super woofer
for the ultra low frequency reproduction.
• Its hi-rigid diaphragm consists in the radial
paper making technique and whizzy hybrid
material realizes the ultra low sound reproduc-
tion, people have never experienced.
•FW800HS also employs the following special-
ized parts for the realistic low sound reproduc-
tion.
•Highly durable diaphragm & cap
• High input 4-layers voice coil
• Large aluminum die-cast heat sink
• Push-pull double spider
•FW800HS’s acoustic parameter is tuned can
be worked with the smaller enclosure - 500 liter.
