Pioneer S-707 \ 64,000 (1 units, 1987 sale) Succeeding the technology and idea of S-3000, the speaker system which was developed. The vibration of speaker unit is transmitted to the baffle plate, in order to prevent the fact that the unnecessary vibration is generated, in the sabot of thickness 40mm the woofer is locked firmly with the frame of aluminum die-cast, furthermore mid range locks on the inside rear section of 2 layer baffle plate, to the eater is fixed in the all baffle plate. By the way the baffle plate 50mm which laminates high density coniferous particle board 2 of thickness 25mm with the special adhesive has become with thick. Unnecessary resonance of the baffle plate has been made to decrease with the baffle plate of high rigidity and lying between the adhesive. Furthermore, in order to hold down the resonance of the baffle plate which is easiest to receive the influence of the vibration, the dynamic stabilizer is adopted. This locks the baffle plate and the side plate left and right firmly with the steel iron-made pipe frame, has decreased the vibrating level of the zone which influences vocal playback substantially. As for the side plate & the top board thickness 25mm, as for the liner 30mm, the sabot to high rigidity it makes convert by the fact that the thickness of the sufficient, 40mm can be given. It is low, [niyuinpurubudokabongurahuaito] was adopted for the diaphragm in the limits, the 30cm cone type woofer is adopted. This it has driven in the magnetic circuit of the large aperture strontium ferrite magnet which is 14000 gauss in φ140×20mm and flux density. Furthermore, LDMC (Linear Drive Magnetic Circuit) you have adopted in order to improve the linearity of the driving force due to amplitude. 12cm cone type [sukoka] is adopted to the middle limits. [niyuinpurubudokabongurahuaitokon] is adopted to the diaphragm, furthermore the ceramic carbon is combined to the center dome. The large aperture strontium ferrite magnet of φ100×14mm which actualizes the flux density of 15000 gauss is adopted to the magnetic circuit. To the 2.5cm ceramic carbon the eater is adopted to high pass. The ceramic carbon purity 99.9% has not used the based material and the binder altogether, actualizes the quality which is superior. 19000 gauss in flux density, the φ85×10mm strontium ferrite magnet is adopted to the magnetic circuit. Network uses the hard board of thickness 5mm, the installation of the baseplate to the enclosure lies between the vibration-proof material, cuts off the vibration. In addition, the enclosure holds down diffraction phenomenon by the fact that it makes the round baffle. With the difference sale, there was a speaker stand which can fill up acoustic material such as sand and blanket inside. Rating of type System 3 ways 3 speakers [basurehu] system bookshelf type Unit It is low the for limits: 30cm cone type For middle limits: 12cm cone type For high pass: 2.5cm dome type Impedance 6Ω Playback frequency zone 30Hz~40000Hz Output overpressure value 91dB/W/m Largest input 200W (EIAJ) Crossover frequency 500Hz and 4000Hz External size Width 394× height 694× depth 365mm Weight 35kg Selling separately: Speaker base CP-707 (2 units 1 set, \ 35,000) External size Width 415× height 275× depth 350mm Weight 12.5kg Theo em, bác nên đổi loa đi vì đôi S-707 này trở kháng, độ nhạy thấp, thùng loa mỏng (tiếng bass không dầy), không có lỗ thoát hơi đằng trước. Đây là ý kiến chủ quan của em, nếu sai xin đừng chấp nhé. Thân.
