BMS 4555 is a powerful 1.5" professional compression driver that delivers outstanding sonic quality in a small package. The BMS exclusive voice coil technology employs a light weight Copper Clad Aluminium wire wound inside and outside of the Kapton? former to improve the heat dissipation, dramatically increasing the acoustic output and reliability of the driver while minimises the power compression.

BMS Elektronik GmbH

Founded 1994 and located in Hanover, Germany, BMS is a leading designer and manufacturer of highest quality transducers. BMS products are used by professional speaker and high-end companies globally.

The BMS advanced transducer technology offers significant advantage over conventional drivers in precision and reliability. We avoid the use of conventional technology like domes diaphragms which generate uncontrolled break-up modes with very audible sound coloration. Due to our unique patented compression driver design, the BMS drivers are extremely transparent and detailed providing outstanding dynamic capabilities.

Almost all parts of the drivers are produced in our own factories to ensure extensive control of results. Voice coil winding, diaphragm forming, CNC machining etc. Every single driver is systematically tested to strict standards to ensure reliability and consistency. The fact that our entire manufacturing process takes place in our own factories has produced a substantial reduction in cost and a high degree of flexibility and efficiency.

The product range is designed to offer superior sound quality able to satisfy even the most critical requirements.

通常是膜片的球顶做主要辐射面,声波经过等化器到出声口的距离较短。此种类型是用膜片的V字形折环做辐射面,声波经过等化器到出声口的距离比较长,频响曲线的中低端灵敏度比较容易得到提升,但是频响高频部分灵敏度和上限比较难做。到底是何原理我也不太清楚,说的不对请高手指正。只是我很久以前拆过一个这样的喇叭和楼主提供的彩照一模一样,也是44芯的。我测试了一下就是灵敏度很高,听起来特别响,其它没什么特别,高频上限不怎么好和B&C比差远了
