The term "efficiency" refers to the ability of a speaker system to convert electrical energy (power from the amplifier) into acoustic output.
术语“效率”是指扬声器系统将电能（功放的推力）转化为声音输出的能力。

Making more effective use of the flux, it assures increased acoustic conversion efficiency and safe operation even when faced with 300 watts max.
更有效地焊剂的使用，确保提高声转换效率和安全运行，即使有300瓦的最大困难。
