Technics, bookshelf's first "center of gravity mount structure" recruitment speaker "SB-C600"

Panasonic will launch a new bookshelf speaker "SB-C600", which is positioned as a "premium class" of the company's technics brand.The price is 110,000 yen (pair/tax included).A coaxial 2 -way unit is a bookshelf -type speaker with a 2 -way and 2 speaker configuration that inherits the new development point sound source and linear phase thought.2."LINEAR PHASE PLUG", which is equipped with a 5cm dome -type tweeter x 1, 15cm cone -type woofer x 1 new coaxial 2 -way unit "Advanced Phase Precision Driver" and corrects the disturbance of characteristics caused by the high -frequency phase shift."Smooth Flow Diaphragm", which realizes a wide sound stage and smooth mid -high range, has been newly launched.LINEAR PHASE PLUG is a function that corrects the phase difference caused by the height of the dome of the diaphragm, delay the progress of the wave surface at the center of the fast -reaching time, and aligns the wave surface around the diaphragm, and generated.Has three functions to prepare.This proprietary shape corrects the phase of the coaxial unit and achieves a wide -directional and transparent high -frequency reproduction.SMOOTH FLOW DIAPHRAGM has a negative effect on the surface of the sound wave, so the woofer part of the 2 -way unit unit uses shallow vibration plates, and the woofer vibration plate to the baffle smoothly connects.Adopt shape.Furthermore, based on the vibration mode and frequency response analysis, the shallow vibration plate has a device such as providing a return reinforcement structure on the outer periphery, adding a subcorn to the center, and division resonance occurs at a low frequency.It is said that the structure is difficult to do.In addition, both the coaxial unit woofer and the tweeter diaphragm material are unified by the use of aluminum -treated aluminum.One of the features of this model is that for the first time as a bookshelf type, the "center of gravity mount structure" similar to the floor stand type "SB-G90M2" is adopted.This means that a speaker mount baffle is provided inside the enclosure, and the unit is fixed and supported at the center of gravity, reducing the shaking of the unit itself when the amplifying plate is amplified, and a stroke of accurate diaphragm with little blurring up, down, left and right.Is realized.Furthermore, the speaker mount baffle has been optimized for a shape that does not impair the air flow inside the enclosure while maintaining strength, based on vibration mode and stress analysis.As a result, the company explains that it has achieved a three -dimensional sound field, which is excellent in the graininess of the sound.In addition, the speaker mount baffle inside the enclosure also contributes to the strong housing structure, reducing the vibration of the entire enclosure.Compared to conventional bookshelf -type speakers, the propagation of vibration to racks and the like is also significantly reduced.The bass reflex port is located on the front side, and has little effect on the installation near the wall."Smooth Flow Port" was adopted to eliminate noise such as wind noise for its shape.The cross -sectional shape that optimizes air flow based on fluid analysis technology minimizes the occurrence of air vortex, which is the source of noise, and the protrusions on the port surface are small -wide distributed in the air vortex.It has a structure that reduces the resistance of noise and air flow.In addition, each part was carefully selected.The network circuit is made of high -quality parts with low sound quality, such as metalized poly propylene film capacitors, laminated steel plate core coils, and OFC (anaerobic copper) speaker cables, and the speaker terminals are made of gold -plated brass shaving out.adopt.The body is matte black finish, and the speaker net is a circular.The playback frequency band is 40Hz -100kHz, and the crossover frequency is 2kHz.The output sound pressure level is 83db/2.83V (m), the impedance is 4Ω.The external dimension is 173W x 293H x 283Dmm, and the mass is about 6.3kg.
