wow seems like he nothing better to do, but gotta give it to him kid got some talent

6:28pm Hawaii

I think i finally got. Can some one please check my measurements if there right. The box is suppose to be tuned to 39-40ish hz. M i right or wrong?

right on man, cool vid. wat kine subs r they?

is that for just one port for the whole box or both ports??????

The gross dimensions is 17.25x40.75x16.75. the net dimensions is 16.5x40x16. M i still close or back to the drawing board again

i think i finally figured out my port lenght. 16.5x3x10, it comes to 39ish Hz. am i right or wrong

but wat does * ,^, mean?

wat dis mean ^ n this * Lv = Av*1.84*10^8/[Vb*1728*(Fb/0.159)^2] - 0.823*sqrt(Av)

would a T-port sound better. wats the advantages with it?

thanks il take a look

that be cool, 18"x40"x18"

wow reall good info thanks man Im going with sloted ports. but ya you all r right the 45s are going to be smaller. oh here is wat i thought it would be this is the net measuerments, going to be using 3/4 mdf;

no not yet, just try to get all the measuerments down, once i do i can start

sorry, its been a month n no could came up with n answer, guess just soo excited to start on the box. i've been stairing at my subs, that are right on my table for the last 4 months

still how long would my port has to be, to be tuned to 40hz?????

so wat size would you recommend?

ohh i didn't you had to exclude the port volume. thought the port vloume was included with the box volume. ok i got another question that you brought up, you said i could raise the volume of the box, what would that do would it make it louder?

im new at dis, im sooo geting lost. ok so make the 45s smaller would give me more cuft?

so wat should i do then make the box a little smaller??

45s might be 3". But im very sure the box is going to 4.5cuft

Need serious help with my ports. The box im going to make has a Net size of 16.5"x40"x16, it comes to 6.11cuft Net. After i 45s all the corners n fiberglass it, the box is going to be 4.5cuft Net, . Im puting 2 RFT212D2 in it. i wanted the box to be tuned to 40hz, but i don't know how long both ports has to b. All i know is that the diameter of each ports are 3" n is 16.5"high. I freakin looked every where on the net n so far none of the site help. So can any one give me advice. Thanks

hey tanks 4 takin a look. ya my port has to be in the middle, the trunk wall of my car where the tires pop up would cover the ports if they where on the ends of the box. I wanted it to b tuned to 40hz. tanks again 4 takin a look man, once i find out the port i can finally start on this project.

N E 1 else can tell me how long my port should be? perrty perrty please

yup u got it man
