Okay I have now 4 Orion H2 12's I need help and dont say it cant be done because that will be BULLSHIT but anyway Im trying to do them ported with them faceing like this

< >
< >

the two on the left will be like one box and the same way with the ones on the right only there will be just one back piece of wood if u know what is I'm talking about, I kno it might sound crazy but just think about takein two boxes and putting them back to back but take off one of the pieces of wood from one of the boxes... But anyway and I wanted to put the port on the side like the new kicker boxes are but I wanted a vent instead of a round port.... I have 34 length, 15 tall, and 30 deep to work with or 34 length, 15 tall, 34 deep....

i know what your saying, and while it will work in theory, what car would DO BETTER because of this? What are you putting it in? Your just saying one box, subs facing away, but have it share a "center wall".

you should know the only thing stoping you is your vehicle.
did you measure what your max dimensions where?

SouthRuninIt
09-03-2006, 02:09 AM
yea and max is 36,36,15 but see if I built a box like that it will not let any air back in the car... thats why I wanted to do it 34,30,15 or 13 OR 34,34,15 or 13(length,depth,hieght)

saywhat?
09-03-2006, 02:13 AM
i would put a port on each end, not both on the same. Just because it would look cooler IMO.

If they are 12's go 14 14 atleast, if 10's go 13

I got cha and what cha mean a port on each end... like if we lookin at the box from out side the car from what Im thinkin you talkin about is a port facein the trunk and a port facein the inside of the car right or wrong

PowerNaudio
09-03-2006, 02:16 AM
well if you place the subs on top and the port to the front of the car you may come up with more bass then you think. then make to top with at least 9" to 10" of clearance from the top. that would leave you with room for air to flow to the front and you have your ports forcing bass there too.

Only thing is about that is I have dynaplate all in the trunk and u should just say the whole car and when I had my 4 CVR's in a sealed box faceing up they sounded nice but not like they should so I changed and went and got two box put them back to back and heard a BIGG diff...

Like me.

I mean if it was you doing it then how would u do it... because wit the subs faceing up its not that loud at all

09-05-2006, 10:37 AM
subs up and port back just to keep them on the same plane

SouthRuninIt
09-05-2006, 06:53 PM
subs up and port back just to keep them on the same plane



So what or how would I do that... Like how would the box look and what would be the dimension and stuff like that:uhoh:

disregard the dimentions...it would look like that, or the port would run along the bottom

what part of alabama are you in?

same plain = subs and port on the same side of box. demensions depends on what type/size box you want.

SouthRuninIt
09-05-2006, 07:10 PM
Okay I see how that box is right but how would I do four on top and the port on the side or the bottom... when the port might have to be something like 4 or maybe bigger

From what I understand you want an Isobaric set up with ported/tuned cabinets? I've never heard of a ported ISOBARIC set up...kind of defeating the purpose of the isobaric configuration/purpose. (see next posting) How much power are you going to run? Isobaric requires smaller enclosure but more power for the same results. Why do you want to run isobaric? (this is the config I got off your "drawing")

"Isobaric - configuration is a good way to get bass in a smaller box. This is done by building a box about half the volume of a sealed box, and placing two woofers facing each other. Note that everything must be sealed, including space between woofers. A spacer between both woofers must be used in most cases to avoid subs hitting each other. When wiring, make sure that woofers are out of phase: Wire one of them backwards (negative to positive, and positive to negative), so that both pull or push at the same time. An isobaric configuration will NOT put out much more power than a box using a single woofer. Its main purpose is to reduce box size. Another drawback is that since one of the subs is exposed, it is more prone to damage."

Nall Im not tryin to do that type of box... see tha thing is I can fit two boxes in my trunk wit the boxes back to back and they will sound off but see I wanna do that but only have one box wit one center piece of wood and I want it to be ported if possible

09-05-2006, 07:23 PM

I see said the blind man to the deaf mute!

---brace the hell out of it! LOL! Seriously...like double up the 'center' piece of wood. lemme see...Ima kind slow! LOL! Okay, 4 subs, two subs each in their own shared and ported enclosure, with one port per enclosure. BUT...all together in one 'chambered' cabinet?

I think I just sprained a brain cell. :crap:

well by the looks of it you have enogh room to put the subs on top of the box 2 subs side by side and then the other 2 right under and youll have about 8.5" left in between them. so using 3/4" mdf for the port that will allow you 2 ports of 3.875" in width x 13.5" high, and about 34" of port length fireing up on the same plane as the subs. with around 3.25cuft per two subs. that would give you a tuning of some where around 32Hz. these numbers are just aproximations and no acuracy to them but you get the idea. put the subs on the side or the top. wich ever gives the sub the most clearance in front of them, ill asume it would sound the best.
laters
so preaty much your same design but with actual values to them. lol

Not sure about this, but without a center divider, having them on different sides and all may cause cancellation?


I would so subs up, port towards seats honestly, thats wat im doin with mine.

So sit tight and Ima let ya kno how it turns out
