How do you know what hz to tune your subs?i am building a slot ported enclosure for 2 12's and i'm looking more toward spl than sound quality.5 cu.ft total and 1400watts(rms) in a 99' 2-dr cavalier.Please help!!!! I want to build this right the first time.thanks all

For SPL tune higher, for SQ tune lower.

Generaly, 35Hz

Be aware that the higher you tune the less low end extension you will have.

I would not go above ~38Hz for a DD. I find that over that you lose too much low end for any enjoyment...

so you want to build a box with a total of .5cu ft for 2 12" subs?

 

[wlmrs 10+ year member]

no,that's 5 cu.ft total.sorry about the typo.also what's the difference between 35,36 and 37 Hz?sound wise what will give me more spl?

 

[PowerNaudio 10+ year member]

there is a difference but its not by much with the lower tuning freq you re likely to get a little more low end bass.

I had mine at 40 and loved it.

I listen to lots of rap and some 80s and classic rock.

i know it is speaker dependant as well, but what tuning (approx) would give a linear response (obviously not perfect) next box i build i might go for a ported but try to achieve the response of a sealed.

 

[wlmrs 10+ year member]

i listen to alot of rap too.do you get more bass with 40 hz?or could you get more by lowering or going higher.this is my first box with a slot port and i want it to perform at it's peak.

Ive realized that for rap sealed works a lot better for me. But thats just me. Most mainstream hip hop will sound good ported like Lil Jon, Ying Yang Twins, etc. But I like my subs to handle everything well not just certain music.

I would stay above 30 hz but below 40 hz. Really up to u.

 

[PowerNaudio 10+ year member]

by more bass you mean louder or lower freq response?

 

[JoseMCeee 10+ year member]

well with 40 hz u wont be able to play anything under 35hz or ur subs will blow. So u gotta cut those frequencies out with a SSF. Im pretty sure it will be louder as in DBs but probably not as much low end as lets say a tuning of 30hz. Ive never tuned that high but I would assume it would be somewhat peaky but I dont know through experience.

how is playing anything below 35Hz in a box tuned to 40Hz is going to kill the sub.

My box is tuned to 48hz... I can send a 20hz tone to them with give or take 200 watts or so... havn't had them blow yet.

Although I wish I had made it lower, the 48hz tuning really isnt bad... but it does lack low end, which I would rather have than pure SPL, especially for rock.
