Crossover Frequency Help Car and PC

[Rayne1995]

I know this may not be pc related but it sorta is. I have the Logitech Z906 and Soundblaster ZXR. So to get the best bass performance where do i set the crossover and what it exactly does putting it at 80hz do.

Also In my car I'm confused I have two 10in subs and my car comes with 8 speakers. so in my stereo i can set bass frequency from 60hz to 200hz and the sub option is Flat-160hz. As for the actual amp on the sub the frequency is 35hz to 160hz. So do I match these crossovers cause I'd rather have the Sub handle all the Lows and my car speakers handle the mids and highs.

So can someone clear all this up cause I don't know what setting the frequency means.

Crossover frequencies are set to separate bass frequencies from everything else.

In a satellite system for example, the main small speakers are usually pretty bad at producing low frequencies, and forcing them to do so will compromise their overall sound.
So we set the small speakers to ignore low frequencies making them sound better, and make the sub ignore high frequencies, making them sound better too.

What specific number you set depends on your specific speakers and how the end product sounds. There are no right or wrong answers, really.
My 7.2 home theatre is set to 120hz. This seems to work well for my B&W speakers and sub.

Not too sure on the car, match them at 160 and see how you go.
If you get too much 'normal' sound coming from the sub, and not just the 'doof doof', you may need to lower that number and see/hear what happens.

Okay so I do know that 4 of my car speakers are 6in and the other 4 are like 2.5in i think. So if it set the bass frequecny to 200hz does that mean it won't go below 200hz or above 200hz

Both. Haha.

My amp, for example, can set the crossover freq for each individual speaker. For a satellite it won't go under that number, for the subs it won't go over.
I assume your car stereo/pc etc knows which speakers are plugged into which outputs, and will do the same.

Easy way to tell is by using your ears.

Okay I'm way to confused but for the car it's a vw jetta 2001 with monsoon amp. my car stereo has 3 settings.

1. Bass Level (-6~+6) followed by Bass-Freq. (60hz~200hz)
2. Middle Level (-6~+6) followed by Mid-Freq. (500hz~2.5khz)
3. Treble Level (-6~+6) followed by Treb-Freq.(10khz~17.5Khz)
4. Sub Level (-6~+6) followed by Sub-Freq. (Flat~160hz)

So the question is Does Bass Level only affect the car speakers and not the Sub.
