The 4 ways speaker system which adopted the
diaphragm by a high polymer element.
A carbon fiber mixing cone is used
for the cone paper of a Woofer, and also the special sound dumping agent is
coated in the top layer. Moreover, the frame holding a diaphragm and a magnet is
a product made from firm aluminum die-casting. The design which stops a
higher-harmonic distorted component with a long voice coil, the copper cap of a
large-sized magnet and a center pole, etc. is carried out to the magnetic
A squawker thinks a directivity as important, and does not make
it a large diameter, but the cone type of 10cm is being used for it.
diaphragm is the lightweight cone paper which improved the rigidity developed
newly. In a magnetic circuit, the large improvement in efficiency is aimed at
with a large-sized magnet and an edgewise volume voice coil, and distortion is
reduced to the center pole using a copper cap.
While attaining a
stabilization of a property in a tweeter at a frame using aluminum die-casting,
the adhesives of the epoxy system are used for the adhesion of a voice coil
assembly and cone paper.
The unique piezoelectric type speaker which uses a high polymer element for a diaphragm is adopted as a super tweeter. This high polymer has many special features, such as vibration system is "lightweight", "a directivity being good since it is a complete drive type", there "there being little disorder of the property by vibration", and "the Dainyuu power being borne."
The enclosure has adopted the
Moreover, a simple circuitry form which adopted MP type
capacitor with few losses in a network, and thought the phase response as
important is taken.
