I need the T'S params for the Type-R, I don't feel like finding them though...got a link?

thanks for the help. What does 45Hz sound like way too high just for max SPL in competition? Just wondering. What is the definition of daily driving? Why dont many people have their boxes tuned to around 45Hz?

Usually for SPL, you want to tune the box a little under the car's resonant frequency, this will give the best #'s...but won't sound good at all on the low end...

Here's the link for the paramaters of the Type R.

So thats why when your daily driving you dont want your box tuned high because there is no low end. basically just really high screaming bass right?

I got 33 Hz...

BUT..did you take into account the thickness of the wood?

If it's 3/4" thick, the box is only 1.33 cubes....

which makes your box tuned to 39 Hz...

I didnt take into account the thickness of the wood it is 3/4". So its 39Hz. Is that pretty good or is there a way I could tune it to hit lower end? See I noticed that a friends Audiobahn 10's in a bandpass went lower than most 12's even some 10's. Is it because it has a lower free air Frequency response? I just want lower bass. Something that will make my nose move, More. Would another 12 in the same box make that happen?

eeeeewwwwwwwwwwwwww

another 12' won't help get the lows in that box

What should I tune my box to, to get lows in a box for my type R's? What should I tune it to? How do I calculate port tuning?

If I'm hitting 39Hz how do I lower my frequency?

Personally I think 35 hz is too low for most rap. I listen to alot of rap and while some songs hit hard most don't most of the rap song that i heard seem to have beat burst at maybe 38 or 45 hz. Now don't get me wrong there are some songs that hit REALLY hard in a low tuned box but for most rap i would go slightly higher end. If you want to hear really low end bass i would do like i did and tune my box to 25hz and pop in some bass mekanik cd's. But that's just what i did. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

I tuned my box earlier today to 33Hz, it was sitting at 39Hz. I noticed a lot of difference between the two. I have to disagree with you that rap hits harder at higher Hz. My sub now picks up those really low notes that I like. I guess its just a matter of taste. At least now I know what to do to tune it right.

Right on man!!! I'm glad you got it figured out and are happy with it know

I was surprised how easy it actually was to make that much of a change in the sound. I just took the port wall from my other box that is exactly the same and nailed and sealed it to my other box. I could have tuned it to 27Hz but I wasnt sure how it would sound. Alpine does pick up those low notes.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
