is a 4" port enough for a 12" bm???

Recommended Posts

i am building a box tomorrow and it turns out i have the room to make it a ported box so i want to go that route.

 

the box will house 2 12" si BM's

there is no good area to place 2 ports next to each other so i am planning on seperateing the 2 subs and each chamber will have a 4" pvc port

 

does this sound like it would work?

 

i will have some pictures of what i am trying to do in a little while

 

Thanks,

~Magick_Man~

here is the basic idea i have right now.

it might change a bit but that is pretty much it.

so if i dont make 2 seperate chambers will the subs really utilize the area in the middle?

you need double that port area.

 

have fun trying to make it fit :(

 

:crap:

 

i am using a port calculator and for 2 4" ports in a 2 cube box tuned to 34 it says they need to be 26.xx"

 

is that each?

 

if it is then that sucks.

because i can fit in up to 14" long ports.

 

would i be better off with 2 3" instead of 1 4" ?

did yo use those port tubes on NoLimits box?

 

no i used a mdf slot port on his.

i am trying to stay away from that on this box because i dont want to mess with angling the port like it is on your box.

 

and i have a ton of 4" pvc pipe so i might as well use some of it.

um, what's the volume of the box (after displacement) and how long are the ports?

 

adding two ports like that (and keeping them the same length) is going to make the tuning A LOT higher (10hz +) possibly.

yeah, thats probably not going to work... the port calc is EACH port, so adding more is just making your problem worse

i dont have the exact number yet but i have about 2.2ish per driver after the port is taken out.

 

i was looking at a single 4" at 11.xx" long which would supposedly give me 34hz with a 2cube box

now i am looking at 2 10.12" long with 2cubes after displacement which should give me ~36hz

 

i will end up with as close to 2.0 per chamber after the port and sub is taken out.

yeah i figured that.

i was using one at 11.xx long shooting for 34hz

now i am using 2 at 10.12 (i think) shooting for 36hz

so i guess the real question is will 2 4" ports 10.14" long in a box 2.0 cubes after displacement give me a 36hz tuning?

 

i am judging this off the port calculator from carstereo.com

:mad:

wtf

that is gay

 

do you know if the box volume you put in includes the port displacement?

the other site said 2 at 10.14" each gave you 36hz with 2.0 cubes after displacement.

hmm i guess i entered it wrong.

 

well shoit...

i think i might just build a sealed box since i dont think i can squeeze in enough port area to have no port noise.

you entered it in for one port... why can't you just have one port? it's probably not enough, but you can see if you like it

it looks that way.

or tune it to 50hz....

 

if i go sealed i can fit both subs on one side and you wont have to move your amp or anything else which would be a plus.

 

and i would almost bet money that the pair of bm's sealed will be louder than the r's ported.

well from what i am told a single 4" port wont be near enough port area for one sub.

and i dont want to build this thing then have it make bad port noise.

i'm sure 2 boxes would fit on one sheet of MDF. it just takes some more cutting time.
