Almost my whole team (me and mark included) will be going to dB drag finals/MECA ohio state finals.
So we'll all have to wear something (hopefully our team shirts) so you can pick us out of a crowd. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I can tell you right now where I will peak... when I go to turn on the stereo for the first time after installation, custom installation, taking the entire back seat of the Sport Trac, with a high gloss finish box matched to the interior of my vehicle, amp rack, neon... when I turn all that shit on, that's where it peaks //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
There would be no peak if I had a box that looks like it was made from wood pulled out of a dumpster, and almost cut to exact dimentions, thrown into my trunk with all the rest of the dirt and garbage... that my friend is an embarassment. Get some class, and you can roll with me!

I dont really care about getting 150db... I just want a nice sounding stereo.. which I beleive I will have.

Word.

Box was requested uncovered, so it wasn't covered? If it hurts your eyes... sue me.

Drop a box off here, we'll test it vs mine... who's will be louder and sound better? //content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif

Talk all you want... I have numbers and a competition history to back me up. What do you have?

 

[Spkrman]

assuming the 2.4 calculation is including displacementwith a 32hz tuning your peak spl will be at 37.4 hz with a sensitivity increase of 3.13 db at 37.4 hz

you do have other options, im assuming you are tuning it at 32 so it will hit the low notes very well, the cutoff in that small of a box will be aroun 29.9 hz, but tuning so low can definetly take away from the subs output, unless you change the box

here is a way to get around that

right now you have about a 3 db sensitivity gain, and you sub will not like notes below about 28 hz

now to get the most output

lets say you change to a 3.5 cubic foot box, and move the tuning up to 34hz

your type r 12" will now hit just as low as the 2.4 32hz

and rather than having a 3 db gain at 37.4 hz

you will have a 5.4 db gain at 37 hz even

BOOST THE SENSITIVITY

so i just made the box bigger, tuned it up, and since its bigger will still hit the low notes exactly in the way your 32hz tuned box will, but with a little higher tuned

gave you a 2.4db gain over the other box

simplified--- if you increase the box size you can get away with a higher tune, not loose out on db's on your low notes, and at the same time, yield more SPL,

RED IS type R 1242d in 2.4 cubic feet with 32 hz tune

GREEN is type R 1242d in 3.5 cubic feet with a 34 hz tune

bigger box doesn't always mean better...

I've tried the R in a box similar to that... sounds terrible and not loud.

Real life > paper

You think that just because I believe the Type-Rs were made by God, called the ultimate subwoofer and sent down to us for our own enjoyment.

If thats the case, just think about all the Alpine Type-R dick riding homosexuals on this forum! //content.invisioncic.com/y282845/emoticons/sick.gif.b1847c8dabbfeeddbcf1a78052249e10.gif

 

[Spkrman]

i would :-D
