penting untuk buat sound tuning.

kalau amp ko ada built-in crossover, tidak payah ko bili outboard elec. crossover lagi.
Ada installer yang sengaja kelentong jual xover sama pembeli padahal di amp dia ada juga xover. Ni kawan saya parnah kana ni.

kegunaan crossover :

1. Low pass filter (LPF) - ni untuk set subwoofer ko main sub-bass. Kalau tidak, pandai ada suara menyanyi la di sub ko.

2. High pass filter (HPF) - ni untuk set midbass/midrange/tweeter ko supaya drivers ni tidak overexcurt or ada cone break-up bila main frequencies yang tidak sepatut nya di main kan.

contoh :

- tweeter HPF ko set pada 2khz. Akibat dia tweeter ko ada distortion sebab dia tidak dapat main rendah.

- midrange ko set HPF pada 50hz, bila ko naik volume. Mid tu akan pecah bila dia cuba main low freq. due to over-excursion. So ko set xover ko p 100hz or higher, mid akan dapat main musik dengan baik pada volume yang lebih tinggi.


dan banyakk lagi bila ko masuk bab tuning for imaging.

begantung apa tujuan ko pakai mid-bass tu. kalau ko mo set dia jadi bandpass, ko kana ada low-pass filter dan high pass filter dalam signal path tu. So untuk tujuan bandpass, bagus pakai outboard elec. xover.

kalau ko mo pakai sebagai mid sahaja, saya rekomen juga ko set dia p 'bandpass' sebab bila mid tu start main 4khz ke-atas, dia akan distort due to cone break-up.

kalau ko ada passive xover, tu xover di amp suda mencukupi (HPF kana ada la)

passive xover = teda power supply. Biasa di guna kan di component set, co-axial speakers, stand alone tweeters etc.
Non-adjustable, if want to change crossover points, kana tukar component.
Basic 1st. order xover ni ko pakai capacitor sebagai high pass filter dan coil sebagai low pass filter.


active xover = ada power supply.
ni yang urg selalu pakai tu yang boleh adjust2 freq. cut-off, level etc.
Ada dalam bentuk outboard atau built-in di amp, player.

kalau amp tu ko sambung p mid saja, masi juga kana pakai passive xover yg kana bagi untuk mid tu sebab ko kana main mid ko dalam bandpass.

Kalau ko set HPF saja p mid ko & tidak pakai passive xover tu, mid ko akan main semua high freq. jadi dia akan distort tu bila masuk freq. tinggi2 ni.

kalau setakat blast sja, ok la kali. kalau mau syok main musik, set dia p bandpass

kalau amp tu sambung p tweeter saja, teda masalah asal amp ko dapat set HPF p 3~4khz.
Tapi jarang betul eh amp punya built-in HPF boleh set ni tinggi. Paling2 pun sampai 500hz saja.
So ko masi kana pakai capacitor kici (as HPF) la untuk kasi selamat tweeter tu dari over-power.

palan2 ba bro. Bukan setahun trus boleh tau semua. Macam saya pun ni banyak juga masi mau di belajari.

paling bagus kalo ko mo belajar, ko cuba bikin install ko sendiri. Mula2 sikit la n palan2 karang nanti ada yg sot. Lepas tu pasang sound sistem kawan. dan jangan lupa belajar buat tuning
