The sound is very pleasant, detailed and rich
Dome type 3-way speaker system developed by combining the advancement of acoustic technology techniques. The cone type 30 cm woofer type takes place in low-pass. The paper cone used for resonance prevents diaphragm cracking by lowering the typing degree (standard to know the degree of dispersion volume) to increase internal leakage. In addition, in order to increase density, the surface is coated with a special resin, the surface is hard and strong, the back side is lightweight structure. For the magnetic circuit, a 4-layer voice coil using a lightweight aluminum wire and a large ferrite magnet with 145 φ are adopted. By increasing the coefficient of force, a design has been realized that has plenty of flexibility in fo and Qo fixation, improving efficiency and improving the characteristics of distortion. urethane board is adopted as a board. The mid-range is 15cm of mid-range dome shaped. The membrane is equipped with a freeboard roll type and a rear cavity is also equipped. As a result, fo is reduced to 230 Hz to improve low-frequency playback capability. In addition, using the double shock absorber method, phenomenon that tends to occur in general rolling input is suppressed. The 10 cm dome tweeter carried out in the high region. A titanium diaphragm is adopted as a diaphragm, and using a newly developed processing technology, 20 um thick foil ultra-thin titanium is manufactured. In addition, by adopting titanium diaphragm, we have succeeded in reducing weight by 30% compared to conventional aluminum type. Titanium foil is also adopted for the edge part, and we have managed to reduce fo to the low frequency of 1.7 kHz. The enclosure is sealed.
