1st number chaser!

[kwitcherbichin 10+ year member]

i am gona try to make a box for 3 12 inch massive cw's and ima try to chase a few numbers with this. now the box ima make is gona have changable ports and such but right now i am worried about how big the port should be. the subs need 2 cf a piece and i was gona add .25 cf to each sub for the displacement and such. what should i tune this thing too and how big should the port be for this application.

i am fiddling around with the WinISD and so far i got this...

i got a 9x10x5 port thats tuned around 53 hz would this do decent or am i not even close.

lol. Way to guess at a peak frequency. I think you better stay in the R & D phase a little longer with the emphasis on R.

thnx for the help =] thats the reason half the people on this site get nowhere cause only thing people can do is just talk. no one can give anyone knowledge about anything cause you all are to busy talkin about how bad or stupid something is. so if someone else is on this site who might be able to help without any stupid talk it would be much appreciated ty =]

theres a pic of what i got so far. workin on 3 diff ports but just tell me if the other port is decent or what i need to improve on.

You have no idea what your resonant frequency is. I am helping you. Don't ask for information and insult someone who gives it to you. Do some RESEARCH. Your tuning is WAY too high.

So what do u reccomend 45?

Don't you search for the resonant frequency in the car and tune to that? Just my noob idea as to how it's done. I'm more worried about SQL though... may work on a LOUD CRX when I get the cash.

for sq reasons I would go for 28-36hz I don't think I would go much higher unless you don't really care about sound and are going for spl.

he stated number chaser... in 6 cubes 100 sq in of port isnt that crazy, it wouldnt make a bad daily box but port could/should be bigger for a number chaser

also since your asking for help with box design you already have your amp chosen right? how much power will you be using, and you have electrical to support that power right?

honestly you need to do alot of research before you post questions like this and you havent done enough or you wouldnt be asking the wrong question

no i have never done a resonant frequency cause i am still a noob at building a box and i dont know the correct procedure to take to build boxes. i have heard of gettin the resonant frequency but i dont know what to do to achieve that.

1) Find your vehicle's peak(you'll need a meter for this)

2) Tune 3-5hz lower than your peak

3) Enjoy deebeez

No, he recommends that you find your resonant frequency. lawl.

well is there anywhere that anyone knows of that has the rf of a 95 chevy silverado extended cab? i dont have the correct things to do this with.

 

[hatedonmostly 5,000+ posts]

You can use any meter.

 

[kwitcherbichin 10+ year member]

all i have is a volt meter =/ i can use that to do this?
