2 lit jit

i think i can mange that bro...thanks...i'll get everything planned out and def let everyone have a look at it... no problem mike...i know you're having fun, and like i said, i'm Definitely not in a hurry... i'm tell ya, i'm learning alot from doing all this asking...hope you get my letter soon and in the mean time, i will be planning my box... thanks

i didn't get what u were saying in the second paragraph...probably because i'm still a newb at this whole port thing...the only thing i think i got is that i will not need that much port area... so basicly GO with the SS specs and give it 35 cube inch of port and get a lenght of 38.5 inches...??? i would really like mike to confirm all this so it can help me and others out before i built it...i assume mike is busy but i'm not in a hurry anyways...won't get my sub for another week and probably won't built it till spring break anyways... *Pulls out HAIR* all this time i thought that you plug in A, B, C, D and you should get a straight answer E...looks like it seem that theres more to it...the only problem is that it seems like everything is not as strutured as i thought it did...meaning that i hope all this is STILL not just some hit and miss in the dark

thank you mrray13, this is the info i plugged in for SIZE of port: Driver Size: 15 Num of Driver: 1 Enter Xmax: 24.6 Tuning Freq: 28.5 This is the output: Min diameter: 9.64" (round port) Min Area : 72.97^2 inches (WTF) Lenght side : 8.54 inches (for square ports) Info plugged in for LENGHT of port: Quantity of Ports: 1 Volume of Enclosure: 2.6 (I wasn't 100% if this is net) Height of Port: 14 Lenght of port: 5.2121 (72.97/14 = 5.2121) Output: Vent lenght: 83.46 inches long QESTIONS: 1.) This was not the result i was hoping to hear from the calculator...why does mike recommend 35^2 inches of port when the calculator ask for 73^2 inches? IF i plug in all the same up there with the exception of the lenght to be 2.5 instead of 5.2121 (to get only 35^2 inches of port), the lenght came down to: 38.53" so whats the deal? hope i'm not asking too much questions just want to do it RIGHT

so you're saying that mrray13's 2 technique will not work? they are perfectly sound to me...please tell me why they won't work...for my sake and every else wondering... i would love to figure out a way to do a bottom port but the lenght to height ratio would not be good...it would be something like 35:1 instead of 8:1 anyways, anyone know how i can figure out the lenght of the port specificly to the rlp's? mike? help

thank you mrray13, i appreciate your help...i think i will go with your first idea of making the port on the back of the box into a wedge shape port with the total area of that side equal to the area of the square port on the front of the box... because the square port is going to be: 35^2 inch of port = (total height - 1.5) * (needed width) --> 35 = 14.0" * 2.5" (front regular port sides on side of box) the wedge area will be: height = 14, triangle base = 4 inches x = 4 * .5 * 14 = 28^2 inches of area, NEED 7 more square inches 7 = x * 14 --> = x = 7 / 14 --> x = .5 so i will need a port of .5" x 14(height) and a triangle port of 14" x 4" i'm thinking of putting a glass top on so i think this will be cleaner than your second idea...on second thought, i might do your second idea if no glass top... |--\ |*|*\ |*|**\ |*|***\ |*|****\ |_|______\ .5", 4" (height is 14", side view) ohhh, i hope this works!! thanks for the idea mrray!!! anyways, NOW how do i figure out the LENGHT now???? *************** *--------------- * * * xxxxxxxxx | * * * xxxxxxxxx | * * * xxxxxxxxx | * * * xxxxxxxxxxx*x* * xxxxxxxxxxx*x* * xxxxxxxxxxx*x* *************** by the way, just to double check, all the X's would be my NET displacement EXCLUDING the displacement of the sub right?

so you're saying i can't use slotted ports? anyways, from their port calculator and other port calculators, i'm "getting the idea" that port lenght is NOT going to dependant on what kind of sub it is but JUST the box volume and the port area... is that right? once again, i'm trying to get some answers because i do not want to base the specs on a program if programs can't read TC subs right...so as u can see, i am quite lost...

alright, i ordered my rlp 15, dvc 4 ohm...def looking forward to it...its going to powered by a MTX 801D...800 rms, in a 5th gen civic coupe...i've build about a dozen boxes before but only done sealed...only lately i've been aquainted with winisd and other port determining programs...so i want to build my first ported box... max outter lenght = 34.5" - pretty much written in stone max outter height = 15.5" - pretty much written in stone max outter width = up to 23 inches on bottom, 19 on top, this is a wedge box... - can be (shorter) smaller, not written in blood max outside cube = 6.49 cubes ********|-----------\ sub is***|*********\ facing***|**********\ this side*|____________\ 35^2 inch of port = (total height - 1.5) * (needed width) --> 35 = 14.0" * 2.5" the main thing is i don't know how long the port is going to be...mike told me winisd does not do a good job with tc subs so i am kinda clueless about how long to make the port to get a tuning frequency of 28-32 with the net volume for the SUB to be 2.6 - 2.8 cubes... although i can put up to a 6.5 outter dementions NOT net cube, i want some space for my junk too...that is why i really want to make the NET to be around 2.6 - 2.8, excluding the needed room for the port dispalcement and the room for the displacement of the wood..., if the total volume can be smaller, reduce the two width sizes with the top always 4 inches shorter than the bottom...I am also very curious about how this is going to work out with the WEDGE box on the back side...i don't know how the port is going to be effected if i need to extend the lenght to the back of the box... i already posted a question in the unoffical forum but hopefully i get some answers here because of the traffic... thanks!!! i hope the answers i get here will help some poor soul too in the future too
