The 20cm cone type Woofer is carried in low-pass.
The aramid cone diaphragm coated [ the special ointment ] with the network of the aramid fiber is adopted as a diaphragm. Moreover, an aramid is adopted also as a damper and it fabricates with high precision, and also the frame part is made into the open structure in order to avoid a harmful air distortion produced on a damper back side.
The ferrite magnet of 110phimm is adopted as a magnetic circuit, and the heat-resistant high nomex is adopted as a voice coil bobbin. Furthermore, aluminum die-casting is adopted as a frame and the polyurethane form is adopted as an edge.
The 2.5cm dome shape tweeter is carried in the high region.
The polyesters cross is used for the diaphragm of this unit. This diaphragm has newly developed matrix cross structure, and rigidity is secured by making a shaping agent every impregnate beforehand of a fiber. It is not necessary to apply a shaping agent to the network currently performed conventionally by this, or to make glass wool touch a diaphragm rear view for reinforcement.
The network part has set up the point most effective for a reduction of the phase distortion generated near a crossover point.
The multi-vent tuning scheme is adopted as an enclosure.
By this scheme, the enclosure has a structure which opened two or more small holes based on the sealing structure, and has controlled internal air pressure by this hole. This stops the superfluous pressure to the diaphragm which poses a problem with a sealing structure, and also the characteristic peculiarity which poses a problem by a bass-reflex scheme is also suppressed.
