yeah use MDF next time, that particle board isnt as strong and might eventually break or shatter.

The port looks extra small if you ask me.But its sposed to be 32hz

Now i'm not sure if i want to add in this extra piece right here are not, if i do i have to cut it at an angle because the subs depth is more than my ports length :Doh:

does she still need bracing, or should i still wait

HAHAHAHAHAHAHAHA

I think you got your port walls backwards. The longer one is probably the first one and the smaller one attaches to it. Any ways can you say hella port noise and improper tuning. Well at least it looks like it from the pics...

Looks like the port is backwards, its gonna kinda get in the way of the back of the sub isnt it

djjdnap
06-15-2005, 12:30 PM
its not screwed down yet, btw.
But no its not backwards, the shorter one is supposed to be thier.
The one is supposed to be behind the sub though, but like i said the 1st port is to short so, i think i'm not gonna use it.(the one behind the sub that is.

yea. thats totally wrong.

the longer piece goes first, then put the shorter piece second.


unless you want it to sound like crap. :laugh:

According to my notes that is right, and using the port calculator..

height of 25 width of 3.5
The lenght of the vent should be 6.8 something.
tuned to 32

edit:
Basiclly the longer the port, the lower the tuning

tRiGgEr
06-15-2005, 12:45 PM
Dude you messed up. The port length needs to remain a constant 3.5" on the width. What are the dimmensions of your box and port???

so this thread was a joke...

if you use the shorter port wall first how the hell are you gonna
compensate for the mounting depth of the sub... genius...

and dont say you are gonna screw it down diagonally like you have
it in the picture... the port width needs to be maintained the whole
length...

i suggest you roll some weed up with your notes and smoke it... because
thats all your notes seem to be good for...

listen to REQ and the others in this thread who have tried to HELP you...

43.5x25x28

the port is 3.5x25x6.8

so like 17cuft
after displacement its like, 14

i think the particle board box was even better then his ported "box"

dam aren't we the critics.
People dont read just post, tsk tsk..


Now i'm not sure if i want to add in this extra piece right here are not, if i do i have to cut it at an angle because the subs depth is more than my ports length.

wow, you just said the exact same thing.;)

djjdnap
06-15-2005, 01:19 PM
essentially i saw a design, like the one i posted. With the extra piece and wanted to see how it sounded, but as i said, the depth of the subs is greater than my ports length. Now all i said was idk if i should use it or not, that extra piece was an ad on by myself.

Ok well are the 43.5x25x28 internal or external? And if you could tell me the actual displacement of one of your subs I can do some quick calculations. It seems way off to me.

Moe Lester
06-15-2005, 02:32 PM
its such a huge box and such a small port that the length isnt going to need to be very long to achieve a low tuning...

Beat_Dominator
06-15-2005, 02:35 PM
For sure he needs to make that port at least 4-5" wide.

tRiGgEr
06-15-2005, 02:44 PM
I used those dimensions as external dimensions. And used .24 for each driver displacement. Just a rough guess they are 18's right?

And the tuning is what around 33-35hz with that 6.75" port. Now that EXTRA piece you said you should use or not, threw us all off. When you design a box you don't have extra pieces to throw in there. Nor should you be even thinking about throwing extra crap in there.

If I was correct on them being 18's. That box has some serious design issues with bracing. THERE IS NONE!

You need to reinforce those walls. They are very thin and that box is so large it needs to remain as rigid as possible, so bracing is a must.

You need to make sure that your port has an even width all the way around. not at an angle from the base like you have in that picture. It looks good besides that.

djjdnap
06-15-2005, 03:00 PM
i'll just reinforce them at the edges, and maybe 2 pieces from top to bottom.
It did say extra piece.;)

Beat_Dominator
06-15-2005, 03:21 PM
We're just trying to help you so you don't have to build another box man..... That port seems awfully narrow for 2x 15-18" subs.

:eyebrow::eyebrow::eyebrow:
confused, the port isn't even nailed down, nor is the front of the box?

The only part secured is where you see the glue...

Do people even read the thread, jeez, i promise i already said that.

just nail the port to your head... shove the sub up your *** and blow...

i would listen to the experts djjdnap-. what would u rather, people whu have done this sort of thing before or you taking the chance of putting in the wrong calculations and screwing the whole thing up

djjdnap
06-16-2005, 08:16 AM
once again if you read, he said it was correct, just not to add in the extra piece.

Just because some people cant fit 18's into thier ricer doesn't mean that they are right...Experts, hahaha, it's nice to have help on something you dont understand, which with this box i do, but as far as being experts i doubt it.

Jesus man, you don't take constructive critisizm too well...You have a lot of people here and several in this thread that have a ton of experience with building/designing boxes. If you think you can't learn anything from anyone else. Well, that's your loss.

The box and tunning is correct. All it needs is some bracing and to throw that *EXTRA* piece away. And It may have a bit of port noise but you will only find out when you hook it all up. It may be cool.

That's it people...

:clap:
Thank you i think, no one was really reading my post just kinda lookin at the pics.:rolleyes:

But i ended up making that extra piece into a brace. Basiclly cut out the middle and put it in the middle. Jumped on the box a few times and it didnt break or budge, so i'm gonna say it should be alright.

Now just gotta wait for the subs:crying:

how do u get port noise ...not enough port area or the ratio between the box vol. and port area or wha cus i just got a box built n put my sxs in and i got some weird noises and the subs dont sound right....but i have triple checked my gains.....

djjdnap
06-17-2005, 08:33 AM
basiclly its you need to round off the ports,
Get some pvc pipe and cut it in half, and stick it on the port, so it will be rounded off.
