北京索威电器有限公司近年研制开发了SW2和SWⅡ两个系列的同轴扬声器。我们知道,著名的英国天朗CPA-5同轴单元采用ICT专利技术。这是运用电感耦合方式输入,即全音域信号送入低音单元,通过电感耦合使同轴的高音单元获得一部分高频信号,达到全频带的输出。索威公司的科技人员通过多年的不懈努力,开发出内悬置技术ISP(Inner Suspend Place)。 Beijing Suowei Electric Co., Ltd. in recent years developed a SW2 and SW Ⅱ two series of coaxial speakers. We know that the famous British Celestial CPA-5 coaxial unit uses ICT patented technology. This is the use of inductive coupling input, that is, the whole range of signals into the bass unit, through the inductive coupling of coaxial tweeter to obtain part of the high-frequency signals to achieve the full band output. Sophie’s scientific and technical personnel through years of unremitting efforts to develop the internal suspension technology ISP (Inner Suspend Place).
