It is 2 way speaker system which adopted the acoustic air suspension system
with small size.
The thing suitable for an acoustic
air suspension system is adopted as a Woofer. Powerful magnetic energy is
secured to the magnet using a 110mm large-sized magnet.
is enough paid also for weight distribution of a vibration system, the
airtightness of corn paper, the compliance of a support system, and the
linearity at the time of the large amplitude.
With a kind of mechanical
filter which equipped the voice coil with the dumpling made from special
composition gum, the high region characteristic is improved and the relation in
near crossover frequency is made smooth.
The rigid outstanding titanium
alloy was molded into the center cap of the tweeter in the shape of a cone, and
is adopted as it. Generating of division vibration is suppressed by this,
directional characteristics improve, and expansion of the piston motion zone is
The metallized polyester film condenser which was low-skew to
the capacitor for networks, and was excellent in the high region characteristic
is adopted. In a coil, direct-current resistance is small, and few distorted
coils containing a core are used.
