I am going out on a limb and saying this is impossible. Anyone want to prove me wrong? Frequency is the number of cycles per second. I don't think that a box can alter the number of times a speaker cycles, at least enough to make an audible difference. My suggestion is to go buy a Chopped & Screwed album......

 

yeah, i was looking for somthing different like maybe type r or X, but i want nothing bigger then 10"

 

and as for the Hz issue, im changing the amount of cycles from the Air, NOT the speaker, it is possible by creating a longer distane for the sound to travel, that is why a longer port makes deeper bass, by the sound traveling a longer distance WHILE having pressure built behind the tunnel, it is possible to slow the frequency down enough to create a deeper bass.
Tech n9ne is my type, ive never listined to chopped and screwed. lol

 

The air is being driven by the speaker and therefore is the same frequency. I agree that over a large distance the time between cycles would increase, but this would have to be a substantial distance and is irrelevant in a mobile audio environment. By changing the box size and tuning frequency you can amplify a range of frequencies, but you won't be able to increase or decrease the frequency of your music or signal.

I suggest you check out this link.

I bet you could get chopped & screwed Tech 9 somewhere, and I am sure you can get Young Jeezy chopped & screwed.....

 

ok, i have looked it over, and you guys are right, but this may help if i spec it to amplify the 40Hz Range, now will this make the customizing really difficult, and will it pay off...

 

40Hz might be a bit high tuning for a daily driver. Playing the sub below tuning at high power can damage the driver. I would go mid 30's for a daily application.
