O.K. first thing is that I read that if you tune your ported box above the lowest frequency you plan on pushing through it you can damage your subs.
Any truth to that? Sounds like BS to me.
I run a subsonic filter so that should be good enough right?

QUOTE: "If you pick a tuning frequency above the lowest frequency that you intend to drive into the speakers, the speaker may well be damaged due to the lack of damping. Below the tuning frequency, all of the control will depend on the speaker's suspension. If you drive the amplifier into clipping, the problem will be even worse. If you're not sure about the proper tuning frequency, use a sealed box or at the very least keep an eye on your woofers for the first few times that you drive them hard with very low notes (and for the idiots out there... DON'T put your eye on the woofers). "


Second thing is that I just bought new subs and box. I got 2 Treo TE 12's in a sub zero enclosure. The enclosure specs say it is tuned to 34hz. I have my LP filter set to about 65-70hz. I can't hear any of the higher frequency bass notes that I heard with my previous subs. All I hear is massive deep low tones. Would tuning the box higher improve this?

I went from 2 JL audio 12W6V1's in a box tuned about 45hz to the Treo's.

Everything is in the trunk of my 91 Nissan Maxima

EDIT:

Another question. How does box size affect sound? My sub manufacturer states 1.6 cu ft for a ported box, but the box I am using is a good bit smaller than that. Would that change the frequency that is dominant? What does a smaller than recommended enclosure detract from a subwoofer's sound? Can it damage a sub?

Get a sealed box , you will be happier and it is easier for some

You appear to be way in over your head

Thanks A$$HOLE!!! Just kidding

Yeah I am probably in way over, but what better way to learn? I could spend countless hours researching. But when I have a full time job, and kids, and a fiance, well there is really not a lot of time.

Plus I seem to learn better by solving problems and experimenting. Hands on is good. I like to get my hands dirty and if I leave some casualties in the wake so be it.

I am not a stupid person by any means, I am an A+ certified computer tech. So I know my brain has the capability to learn this stuff and retain it fairly well. Just need a fast track to the basics and will be asking questions.

Since this is the "dumb question" area I figured these questions would fit well and hopefully be answered.

Thanks for the response though

Anyone have an answer to ANY of the questions above?

For the first part if you really want to learn a lot of stuff quickly there is a website that explains it all. It's Basic Car Audio Electronics

Now for the part about tuning the box. If you have an infrasonic filter (subsonic is not the correct term) then that will be enough to keep the driver from damaging itself. Did you put the Treos in the same box as the JL's? If so then it may not be the correct box for it. The tuning on the JL box was 45 Hz correct? That is probably why you were hearing the "higher" bass notes. If you current box with the Treos is tuned lower it wont be able to efficiently reproduce the upper frequencies.

The Treo's are in a new box. Tuned to 34hz. I found the problem with the sound I was getting from these speakers though. I accidentally turned the bass boost on at the amp, which I NEVER do. Sounds much better now.

So all questions have been answered except one(well actually more than one )

How does box size affect sound? My sub manufacturer states 1.6 cu ft for a ported box, but the box I am using is a good bit smaller than that. Would that change the frequency that is dominant? What does a smaller than recommended enclosure detract from a subwoofer's sound? Can it damage a sub?

Usually a smaller box can make it boomy and peaky. Im not sure what it would do with your treos. It will not damage a sub unless you go extremely small. If I'm wrong at all anyone please correct me. I can't really comment on what it will detract from the woofers sound because i don't have much experience with that.
