新手~分頻器一問...
想問一下Speaker個分頻器, 係用來分頻. 想問下我test過個分頻器.結果係甘1kHz to 15kHz, 高音單元同低音單元都會有聲. 甘係唔係代表個分頻器有事?
我個分頻係bi-wire, 我已經remove左個jumper來試, 無論幾多Hz, 奇實高低單元都會發聲.... thanks
Re: 新手~分頻器一問...
Try to ans your question by simple thoery.1. It depends on the filter design, if using "n" order, it can filter more details, but will have more distortion on sound level and have great phase error.
2. If you totally want a sharp cut off, you can try using "Electronic crossover" applying at pre-amp stage. The response of that filter look like a "right angle cut off curve".
3. It depends on the frequency response of the driver.
i.e. Woofer spec quote : 20Hz to 1000Hz, (+/- 3dB), it mean you can still heard 2000Hz but the sound level will be down to -10dB (let say),
Tweeter also same as this.
