FW800HS
FW-series
•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.

P16 HP sound reflector
HP sound reflector eliminates the standing waves
in enclosure. HP’s 3rd-order curved surface
structure is ideal form and strength to extinguish
naturally the standing waves by making sound
reflected diffusely.
P-30 brass tweeter stand
P-30 is the tweeter stand made of brass,
which minimizes unwanted resonance
and improves high frequency sound.
