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 circuit.
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.
A 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 bass-reflex type.
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.
