Need help understanding hz/tuning

[GrandCherokee 10+ year member]

so basically the lower the box is tuned at the more lower bass itll pick up?

....something like that?

how would the hdc3 18" be in a ported box tuned at 35

and what would be the difference if its tuned at 38hz

No. The specifics of tuning are quite involved. I don't have a link that will help but I would search before making a thread next time.

get me the theile parameters for it and give me an enclosure displacement and I can tell you the differences

not much difference..... the only thing a specific tuning guarantees you is that the excursion will be the lowest at the tuning frequency.

It depends hugely on your specific exact situation, but usually you get more peak out of a higher tuning (assuming its not ridiculously high), but you can never play loud below the tuning frequency. The difference between 35hz and 38hz is pretty minimal, but can still make a noticeable difference. Chances are with a 38hz tuning you'll have a slightly higher peak and be slightly louder at that peak, but the farther you go up, the less low end you get due to raising your lower limit, and the less benefit you get from it due to diminishing returns.

Hope that answered your question

Technically yes,

The lower the frequency you tune a box to, the lower it will play effectively.

It all depends on what you are tuning for though.

Are you tuning for a peak at that frequency for SPL?

Or are you tuning an F3 of the box to know how low it can play before unloading?

I believe there is a great misconception on tuning.

There are multiple things to tune to when designing a box.

If designed for SQ, there will barely be an audible difference between 35hz and 38 hz. especially since an ideal SQ enclosure will have a very flat response.
