nbs reg cab 3 jlw3 10's build

[sgtshaft919]

Ok so i got tired of my old crappy pioneer tens and a make shift box that we kinda threw together so we started playing around... i aquired 3 jl0w3's. we tried to do the behind the seat thing, but since i am tall and fat it aint working. So out first kinda goof off idea was i took the ported console box tthat i made like 6yrs ago that i had in there with the pioneer 10's and we basically cut another hole in it... i sounded...ehh ok it db'd at a 133.7. it looked like sh*t and we wanted to do soemthing different. pics of rigged setup....[IMG][/IMG]
with the sub cut in...[IMG][/IMG]
so what we have come up with is a downward firing center console that will hold all 3 subs.. it is ported and tuned at 34hrz. we got it al cut and are waiting for the glue to dry. so i figured that i would post pics and get some feedback...

Is the particle board permanent?
I'd change that to MDF a.s.a.p.
Cool idea tho.

[sgtshaft919]

its particle....they were out of mdf.. we just wanted to see how it would sound...then i will build a permanent one..

[sgtshaft919]

It is finally all glued up and sealed... turned out really good...tonight i am going to cut holes in the bottom and put the legs on, and then test it out... lemme know what ya think..

I see your missing a rear bumper, I will get that roll pan to you ASAP man.


But the box looks great! Great work man!

[sgtshaft919]

yeah i got this guy who has a rear bumper...just real hard to get a hold of....

You will have port noise.

[sgtshaft919]

port noise?

[Dyabolical]

Audible noise coming from the port, like whistling or any other sound not created by the sub itself.

[sgtshaft919]

that port is to spec.. if that is what u are comenting on...other than that feel free to sahre any thoughts or concerns..

[Dyabolical]

What are the box specs? Gross volume? Port area? port length?

And the port noise will come from the front baffle extending over the front of the port, it creates a very tiny amount of disturbance but impacts the entire ports airflow. The noise might not be bad, but there will be atleast a small amount of port noise.

i doint remember all the specs off hand i got them at the house...the port is to jl spec on that. hey called for a 4 inch round port nine inches long. that is the square equivilent.. the front baffle doesnt stick over the edge of the port. besides that is a down firing box. the port is on the top....?

Well whatever that lip is that sticks above the port. Also you do realize that port tuning is also dependant on the overall internal volume? That is to say, if the spec says that you need a 4 inch round port nine inches long with an internal volume of 2 cubes, the same port with 2.5 cubes will yield a different tuning frequency.

the box was built from dimesions on blaubox. it is built and designed for 39 hz

[sgtshaft919]

ok finally got it all sealed up and installed last night at about midnight.. sounds amazing... very clean deep punchy bass. we metered it and was like 134 at the dash and 148 at the port. fitment was awesome.. i just thinki need more power...lemme know what u think i should finish it in...

you dont have leaks in that box? some of the cuts didnt look straight in the test fits.

good design, I would cover it in vinyl if you can get it.

[sgtshaft919]

no air leaks....came together awesome...if i were to lay viynl do i have to lay something underneath it?

[FastBlak]

I would recommend putting a thin padding on it first before wrapping it. Looks like a nice build btw!

[silverado2nv]

is your port facing foward or backwards?...I have going foward, nice build

[sgtshaft919]

it is at the back of the cab facing upwards...
