diy砌喇叭

hi all bro,

如果我diy砌喇叭用作 av amp 後置用途:-

1.有齊高低音單元聲箱, 請問如果唔落分音器,唔落電容, 咁會有咩後果?
2.如果要落分音器,落電容的話, 最簡單又平就可以出到好聲的方法是怎樣呢?
3. 我的 av amp support 最細 6 ohm, 但我的低音單元是 4 ohm, 我應該怎辦?

請教請教....thx

有趣 :  :
如不用分音器， 我猜D 声会重叠导致模糊，定位不准。。。
如不想用分音器，不如用全频单元(FULL RANGE DRIVE)。。。。

定位唔好, 好大問題

沒有3 D 不如唔好聽 :roll:

Seem similar post in review 33. Anyway, try to ans your Q.

1.有齊高低音單元聲箱, 請問如果唔落分音器,唔落電容, 咁會有咩後果?

The HF will burn easily.
The dB in WF and HF driver is not same, so may be HF louder than LF via versa.
If you can find same dB level of 2 driver, and can get two cut off freq. are pure sharp driver, you can do this.

2.如果要落分音器,落電容的話, 最簡單又平就可以出到好聲的方法是怎樣呢?

Single pole crossover network, the cut off is not sharp but less distortion and attentuation, phase error is lower.

3. 我的 av amp support 最細 6 ohm, 但我的低音單元是 4 ohm, 我應該怎辦?
In series of R 2 ohm, but remember, in AC signal, the impedance is change according to frequency. You need to measure the Z (impedance) according diff. freq.

Hope this help.
KK.

很少不支持4ohm，頂多在4ohm load 時功率不足。

先答——有齊高低音單元聲箱, 請問如果唔落分音器,唔落電容, 咁會有咩後果?

后果是很严重——高音会烧，中音可能烧不了，如果承受功率很大的话，但都很难全身而退。
最后你有可能只剩下低音，会发出没中没高的沉闷中低频！     

哇！有KK sir 和 谈兄在真好，可学到好多东西 :  :
