I am installing an eq and it has a selectable low pass crossover, the settings are 60 and 90Hz, what should I set it at? I have to select which one I want before I mount it in place as that switch will be covered. Right now, I have my low pass crossover on my head unit set for 80HZ. Im thinking 90Hz would be the way to go. I have 2 Cerwin Vega HED 12's in a sealed box.

 

You should have done a little more homework before buying and slapping in an EQ without knowing where to set the frequencies at.

Im not setting frequencies, im setting a frequency. Have you ever heard of getting people's opinion? That's what I was doing. Instead of waiting for an *sshole like you to respond to this post, I did what any person would do, hooked it up and listed to it in both positions, 90 and 60Hz, and made my decision based on that. F*ck homework, listen to the sh*t.

 

Although you have already set the crossover point at 80 Hz at your head unit, setting your EQ low pass crossover at 90 Hz should be good. (since frequencies above 80 Hz is already being attenuated).
A good rule of thumb is to set a low pass crossover to the lowest frequency your front stage speakers can handle without distorting the rest.
Usually, the lowest frequency your front stage speakers should be your low pass frequency (or around that value) without muddying the higher tones. This is to keep the less omni-directional bass tones from pulling the sound stage towards the rear to some degree. (Remember, the higher the sound tone, the more directional it becomes. ie. voices vs. "quad" bass)

 

This is for my subs only.

 

What xivera is saying is that your subwoofer crossover freqency should be dictated by the strength of your midbass drivers.

Meaning, if you have 8"s for midbass, you can cross your sub lower then if you only had 4" mids.

Generally, the lower you cross your subs the better, but at the same time don't sacrifice the quality of your mids.

 

Did you hook your fiber optic cable up yet?

I think that 90Hz should be fine. If you cross it at 60Hz, there's going to be a lot of lower mid-bass and higher sub-bass frequencies you won't hear.

Good luck

 

Who said I had fiber optic cable? I was gonna ask if you had taken your head out of your *ss yet but judging from your sarcastic question, it's obvious your head is firmly implanted:fawk:

 

Gotcha. It would be nice if I had mids up front from which to judgeh: I have some Kenwood DualMags coming, I doubt they are very stong as far as midbass is concerned so I think I'll stay w/90Hz that way im not missing out on so much of the lower frequencies.
