一、额定阻抗。常见的额定阻抗有4欧、6欧、8欧、16欧等。由于目前音箱使用晶体放大器一般都不使用的输出变压器,所以连接喇叭的阻抗,大都在4—16欧的范围内。8欧对于输出、音质及稳定度等均为最佳,所以最好选用额定阻抗为8欧的音箱。二、有效频率范围。频率范围越宽,则频率特性越好。有效频率范围在国际电工委员会标准中有严格规定,现
First, the rated impedance. Common nominal impedance 4 Europe, 6 Europe, 8 Europe, 16 Europe and so on. Due to the current speakers using crystal amplifiers are generally not used in the output transformer, so the impedance of the connecting speaker, mostly in the range of 4-16 Europe. 8 Europe for the output, sound quality and stability are the best, so the best choice for the rated impedance of 8 ohms speakers. Second, the effective frequency range. The wider the frequency range, the better the frequency characteristics. The effective frequency range has strict rules in the IEC standards, and now
