You tune your box to what you listen to. The "safety" aspect of the tune is that you need to tune the box to lowest note you will play them at. When you play your subwoofer below the tuning frequency, it doesn't make much noise and the port doesn't regulate the subwoofer's movement, and if you're driving them hard, you can rip the cone, surround, or spider from over excursion. As bones said, 35 Hz is a pretty common tuning. Unless you're trying to wang on some really hardcore chopped and screwed songs, 35 Hz is a great tuning frequency.

Anywhere between 33-40 is good

I actually like 33 myself. I try to tune everything to 32 or 33.
LOWAR == BETTARRR

Getting super low is fun, body panels = waves in the ocean lol.


I've always wanted to build like a box tuned to 20 Hz and try it just for the lolz. I wan't it to sound like an earthquake rumble. It'd be barely audible and would **** in the rest of the sound range, but it would be hella cool to show off.

Actually, tuning low (in most cases, depending on the drive, suspension, etc.) will give it a flat response so that it's not boomy. The point is never actually get to the tuning frequency, so you just ride on the downward sloping curve, in terms of port gain.

so do it, youd be surprised.

now as far as the sub the op is working with, tuned @ 36-37 that thing pounds and for some reason it has great authority down low still

Its all dependent on your vehicle.


Example, I tuned a few boxes too 40hz in my Explorer and it was no audible difference on the low notes from a couple I did at 32 or 35hz, but the low tuned ones did lack on upper end.

I saw some website where some guy used some of that cheap sono tube stuff for pouring concrete and made some folded/curved really long aero ports, tuned it down really crazy low, like 20 Hz and then put legs on it and made it into like a table or whatever and used it as the subwoofer for his house. I'm guessing he tuned it that low so that explosions during movies, which are really low frequencies I'm guessing, wouldn't blow out the subs. That sono tube stuff is dirt cheap and I've got some extra MDF laying around, I just may go buy some cheap pvc fittings and give it a try :D

My hybrid horn is tuned to 27hz. Never heard a pair of 10's that could murder the lows like they can.

Did you design the horn yourself or did you just find the design somewhere, those are really interesting, I would love to know how those are calculated up.

so i think the safest for my 15" is 35

Just look at Thummpers 2 10 horn think.

It does 145s legal at 22hz.

But I'd like to see what it does on 40hz to 55hz

I pretty much copied thummpers horn. Knowing outside sizes and guessing port width I made my own.

6 sided sealed box. Leave the subs at home. That would be safest.

Testla did not choose the safest frequency.

I'm having a similar issue, but with an Infinity Perfect DVQ 10". I decided to go with a ported box, but I know that I don't want too much punch, just a good fill. However, I still find sealed boxes lacking. In terms of the music I listen to, it's random, but there's often a lot of kick bass as well as boomy bass. I decided to let my comps handle the kick since I can't get both regardless of enclosure.

Anyway, the question is how do I equate the sub's place in my trailblazer to account for the free air outside the box, and how does that effect the frequency I tune the box to?

how does speaker size determine tuning in your mind? i gotta hear the all elusive answer to this lolz.
i have tuned 10's at 29hz before but it was strictly a boomer only.

I DID THIS!!!! About 5 months ago for a ht setup. used my old kenwood tornado cone 10". WAS SO AMAZING! hit some really low notes! REALLY LOW! until i blew the sub :crap:
