when you say change it to 36" is that short enough for it to not have a bend or will it have a bend?
and is the volume accounting for woofer displacement? its not much but do you think it will affect anything?
Thanks for all your help by the way. i really appreciate it.

any input on the box would be appreciated. id like extra confirmation before i build

ok so i used sketchup to design the enclosure you mentioned to the best of what i could tell you were saying.
Did i do it right? is it tuned correctly? whats it tuned at?
Oh and i think i kinda went overbaord on screenshots, lol

That sounds like a really good idea, and i started messign with my calulations with .75 inch mdf an yah im gonna go with that.
On that design you just came up with, is the double baffle on the back with the subs back or the front? if its the back then that cant be done. there isnt enough room between hatch and box to do subs back without modifying the box. I can do sub up or sub forward.
Thank you for all the help so far, i really appreciate it.

ok how bout this, 1 inch mdf, 40.5 inches wide, 20 inch depth, 17.75 inch height. Side firing port thats 5 inches tall x 18 iches wide. my calculations may be off. will model in sketchup for reference
tuning is at about 31.61 htz

or actually, how many four inch aeros would it take? if they were all across the bottom it'd be cool. it'd be a lil extra cash but itd be worth it. would i have enough airspace after?

anyone have anykind of design ideas?

No you would need way too many 4" ports. Aero's probably won't work in this scenario.I take that back. Two of their 6" kits wouldn't be enough, and third would be too much.
maybe 4 inch? idk, never really messed with aeroports. are they hard to install? how do you do it?
yah thats kinda what i thought, was hoping maybe four four inch across the bottom would work but, oh well. Damn, well time to rethink things. BACK TO THE DRAWING BOARD!! haha

are there any disadvantages/benefits of doing single chamber over double with center port?

is that with 1 inch walls or 3/4 inch walls?

1"
do you think 3/4 inch with double baffle and little bracing will get me at least 4 cubes with 75 in^2 port? tuned at around 33.3?
Yes you could be right around there, just depends on how much bracing. Use wooden dowels or all thread to save space.
idk how to brace with all thread so i was thinking 1-2 inch wood dowels.

Consider using aeroports. They are more costly, but you can typically get away with less port area due to their flaring.
how many, what size and how long do you think they will have to be?

hmmm, i wonder how much port area i have right now. -___- def not enough. haha not much thought was put into first box.

oh and there will be bracing also, and do you think it would be better to go with single layer 3/4 inch mdf all around and double baffle?

ok well if i do 1 inch mdf all the way around with max dims. no flush mount baffle. Id get around 6.31575 ft^3. thats my max size for a box in my car without taking up rear seat space.
whats an ideal amount of airspace for two 12 inch xcons? minimum for the two?
How much port area can i get out of it with what i have right now?
0 -
lol, how much airspace would i have left if it was sub up/port back with the port at the bottom at the width of the box(38.5) with a height of like 3.25? and how long would it have to be?
0 -
oh using 1 inch mdf with a 3/4 inch flushed second baffle
0 -
well if i go with like 112-130 in^2 of port do you think id still have enough space to get 4.5-5 cubes of space out of the area that i have? Max dims are posted above.

i plan on using two american bass vfl 120.1's strapped. Planning to tune at about 33.3htz

Yah i pm'd him, waiting on a reply, but i figure i might as well ask anyway.
Oh, how much port area would i need for the 2 12 xcons?
0 -
oh max dims are 40.5width, 20depth, and 17.75 height
not really needed but eh might as well put in the info for if i ever need help designing it.

ok so im designing a box for two 12 inch xcons, ported going into my 2007 scion tc(Hatchback). Right now i have a decent box but its time for a rebuild.
My box right now is 40.5 inches wide, 20 inches deep, and 17 inches high behind the rear seats. Its tuned at about 29-31 htz(not too sure). It does a 143.7 on the meter sealed up on the glass. No deadening, no beauty panels.
But my concern is that my port is an Lport on the drivers side, it only goes halfway across the box so one woofer is above the port and the other is not. Im worried that the sub above the port is loading off of it and the other is not.
If it is i want to fix this, so a rebuild is underway. It has been almost a year with this box so i might as well.
What i want to know is, what is the best placement of the port and woofer? Sub up/port back? Sub back/ Port back? Sub forward/port forward? sub up/ port sidefiring? Sub forward/ port sidefiring? Sub back/Port sidefiring?
Im using winisd to help design it and also using google sketch up.
I am going to be putting two 12 inch xcons D1 woofers on about 2400 rms(soon to be ALOT more tho)
What amount of port area do i need for the enclosure?
will be updating this thread with more info as i go, along with shit loads of questions. Also going to design each enclosure and post a pic from sketchup of it along with specs, so i can get some sense of confirmation.
kinda doing this to see if a better design will put up a better number. still with no deadening and no beauty paneling. Then will add beauty panels and test again, then remove it all and deaden the shit out of the car and see what it does. IDK why i wanna do that, jus kinda curious i guess.

2 12 inch SSA XCON box design ideas and I need help
in SPL & SQ / Fabrication
Posted · Edited by NickHall
but isnt it supposed to have 5 inches of width all the way through? with that at 36" id have 3.75 inches or so at the end of the port if it didnt bend.
what would port tuning be at if i didnt change the box at all?
i can go a half inch more without bending the port.
