Technical question on ICE

[Kianbeng]

This is a pretty technical question. I hope I can get some advise here. Otherwise, I'll appreciate if anyone can direct me to any website/forums which may have this answers.

 

Here's my question:

 

I have a input signal (with HPF at 150Hz) and I want to add a LPF and HPF at around 2KHz, such that I get 2 outputs. Output 1 at 150Hz - 2KHz and output 2 at 2KHz onwards. What's the exact capacitors should I get? Is there a place for me to find the formula to calculate this?

 

I know the easiest way out is to buy a electronic crossover and just turn knobs. But I'm keen to build this myself for the purpose of learning. It's very interesting actually.....

 

Thanks

y u want capacitor for?

 

capacitor just to store charges from ur battery so that ur amp gets constant power..

 

u mean u wannna strip open ur amp and play ard inside ah?

[Kianbeng]

No. I meant a capacitor used for filtering high frequencies. ie, a 1uF capacitor....

 

edit: or even a coil....for LPF...

Do a search on the internet lah ... seen a few sites where people DIY make their own crossovers.

Might be someone here who can help you.

There are hell lots of information out there. Such info is definitely on the internet. I'm aware of this. But many a times, I come across crossovers which are designed for 8omhs speakers...or with 110V....or with other scenarios different from mine. I'm looking for such info based on 4ohms speakers, 12V, blah.....I haven't found any which is of use to me yet.

 

Bear in mind that the question I asked is specific. Not a question which has been asked many times again and again. As such, I don't understand why you have to say "Do a search on the internet lah".

 

I can easily go into another thread where ppl ask about "How's the performance of xxx" and I just easily reply "Do a search on the internet lah". This doesn't help anyone.

 

Maybe I'm lousy with searching. Maybe you shouldn't make such comments. Maybe I just had a bad day.

should have kept my mouth shut ...

[Kianbeng]

I'm sorry if I have offended you. Maybe it's me who really had a bad day.

Just checked that forum and I think it's .

 

Thanks

I guess giving useless advise is a waste of resources and time.

We all start somewhere somehow sometime.

So let's be friendly and help each other here.

There is another audio forum that is coupled to this DIY one. It deals with the non-DIY stuff, do take a look. These forums are all about ICE and these people are quite serious 1. But still search using their search function to avoid repeated topics.

 

Here's 1 more that I don't understand, seem a little to deep for me. You can try.

no problem. the above DIY forum is best for your need i guess . the below one is about ICE but less DIY:

Hi wbucket,

 

The delphi forum is exactly what I needed man. Infact, I also found the 12volt.com website from there. And they are all very good. Think I always saw some of your posts there....

 

[Wbucket]

Just trying to help. Although I am new in term of ICE too.

[Kianbeng]

That's alright. 2 months ago, I know nothing about ICE. Now I'm picking up interest....but more on DIY so as to learn. Btw, I'm not a engineer unfortunately so I have to learn whats a uF, mH....blah....not easy.

 

Should have studied engineering.
