Crossover frequency分频点 / 交越点
Full range全音域 or Multi-way多路 2/3/N/.5："N.5-way" usually indicates the addition of a cond woofer that plays the same bass range as the main woofer but rolls off far before the main woofer does.
Filter slopes衰减斜度of crossover networks –
1st order一阶分频 (6dB/octave)

2nd order 二阶分频 (12dB/octave)
3rd order 三阶分频 (18dB/octave)
4th order 四阶分频 (24dB/octave)
Frequency频率 一般过去时练习题及答案– expresd in Hz (Hertz) 周, kHz (kilo Hertz) 千周, MHz (Mega Hertz) 兆周, etc.
Frequency spectrum频谱
Audio frequency音频covers range from 20Hz ~ 20kHz
Sound pressure level (SPL) 声压电平
Efficiency效率and Sensitivity灵敏度
Sensitivity is expresd in decibels (dB) 分贝.
Is one filter slope superior to another?
Theoretically a steeper filter slope results in a more uniform frequency respon, which is vital in the reproduction of classic music. Nevertheless, this can be achieved by adopting the much gentler (1st order) filter slope with appropriate correcting circuit (equalizationscud).
