This changing "reactive" load causes the amp output level to change with frequency and changes in speaker impedance (a dynamic thing that changes as the speakers are driven harder).

这种变化的“反应”负荷导致功放输出水平的变化与频率变化，音箱阻抗（动态改变的内容作为扬声器驱动更难） 。

Negative feedback makes the amp sound "tighter", particularly in the low end, where the speaker resonant hump has the most effect on amplifier output.

负反馈使放大器声音“更严格”，尤其是在低端，那里的一位发言者谐振驼峰拥有最影响放大器输出。
