say a box is tuned tom 35 hz, what would that do when notes below or above tuning are played?

what did you search for?

below box tuning the sub will reach its mechanical limits quicker with less rms watts.(moving in and out in easy to understand terms) that is unless your amp had a suitable sub sonic filter.

What is your real question? are you planning on building a box or something?

might want to raise that up a bit if your amp puts out close to the rms of your sub.
i would recomend 32-34hz on the ssf depending on the output of the amp.

the amps putiing out 3200 rms. the gain setting turoral said to set it at 26

It is best to have the SSF a half an octave below tuning.

how much is half an octave?

In music, an octave (sometimes abbreviated 8ve or 8va) is the interval between one musical note and another with half or double its frequency.

I'll take this one...since I asked a similar question a long time ago. Basically an octave is a 2:1 ratio. An octave higher then a said givin frequency would be double that. An octave below would be half the said octave.

So for example. You take 100hz as your said number. One octave above 100hz is 200(100*2). One octave below 100hz is 50(100/2)

So I guess what noah is trying to say is....you would take your number 35hz.....and it would be half an octave. Well an octave down from 35hz would be 17.5 hertz. but we only want half...so a half of 17.5 is 8.75...

so 35 - 8.75 = 26.25. I'm pretty sure thats how it works unless my interpretation of what I was told is incorrect. Which if it is someone will correct me I'm sure. Hopefully the person that sent me this info will chime in ;).

My response was more in reference to the noob trying to give advice rather than asking questions and Jmac smacking him down. Quite funny after a few beers.

:rolleyes:

You should set it to 1/2 an octave below tuning (which is conversative itself, especially w/ today's high-Xmax subs), which is 0.75*TUNING and, in this case, is 26 Hz ...

Setting the SSF @ 32 Hz means you're already -3 dB @ 32 Hz, which means you're taking a huge portion of output away @ tuning, which is highly unnecessary considering that's where you have the least movement ...

**** n00b '06ers ...

Honestly I know you dont know me and such, but this guy seems like he knows little of car audio, and for all we know he is sending that 3200rms(which i dont know if its a joke or not) to a 1500rms sub. I would not want to throw that much to a sub(rated as I stated) in a ported box at a frequency much below tuning. I was just trying to help him not blow up a sub. Notice how i speciefied (easy to understand).

If he truly had a 3200 watt amplifier, he would have the experience to know what box tuning is, even if he doesn't know how to do such.
