I'm having trouble finding anyone local that can design an enclosure and cutsheet for my 4 15" SoundStream SPLX's. This will be a daily driving with no comp use in mind. I would like a 3D diagram and full cut sheets. I want subs up and port back. I have $10 in paypal for a skilled blueprint design and cutsheet when it's all said and done. Thanks!

SoundStream SPLX-152
2005 Ford Explorer max dimensions
Top of 2nd row seat to rear hatch = 40"
Bottom of 2nd row seat to rear hatch = 44.5"
Width = 45"
Floor to top of seat = 18"

I came up with 16.44ft^3 after sub and port displacement. I have .49ft^3 left over from the gross total of what my max dimensions give me
and would like all of the .49^3 used for bracing.

Calculations with WinISD:
14ft^3 NET
35.07hz
13.5x13.5 port
17.25" long
182.25sq inches of port area
One of the side walls will be used as a port wall

I can help you out, but I'm kinda confused about your dimensions.

do you want to slant from in top of 2nd row seat to rear hatch bottom by 4.5"... or something like that?

Yeah, thats exactly what he means lol......Due to window he can't go as far back as the bottom can


EDIT: Slant is for seat

hmm.. so you want the port on the slanted side? or am I thinking backwards and the seat is what is slanted???

Its probally that the seat is slanted......Just go by the seat being slanted and he will be back in 45 mins or so

Here you go... this is a double baffle design 13.5 cu/ft (w/.25 extra for more bracing) @ 34-35 Hz (depending on the extra bracing) with 156 sq/in of port.

Lol so much for the 1:1 port ratio huh? ......but geuss its the port style you was going for

Wouldn't have been easy to do the 13.5 x 13.5 and still have the drivers fit in the box.

It's do-able if needed, but there should be zero problems with the port this way.

Wouldent the port be all the way up against the hatch in that design?

rpfuror

sure, but where else you going to put it? I can try to put it up?

So it would be up against my hatch with no clearence? I would think I'd need some room between the port and hatch? No?

not entirely.

never heard of the 1:1 ratio.

1:9 comes to mind, and that design is perfect for that


RP

have the subs like this

----------
....OO....
O****O
**** = port

Most people on here will tell you 1:8 ratio is about the highest they would go

I like to stay with 1:8...

Platestacker45:

First, you want clearance for the port at least the width (height in this case) free.

I can try to put the port on top if you would like, it will be a much more complex build to get the tuning you want though.

I'll put something together.

Do you think it will still be as loud/sound as good as ports back though?

well.. it will be Way better than blocking the port... Really its different for every setup.

I have a jeep cherokee and I have tried every different type of box and firing every way. Port up subs up and port back subs up were about the same. The benefit I saw with both up is there was less noise from my back tail gate.

ney way.

here you design, same specs, just moved/re-designed the port.

That looks like it's gonna take some time to build..

Width by Height

1:1 ratio example is 12x12

1:5 ratio example is 2x10

not sure how to explain it lol

the 2nd box looks bad *** it shouldt be that hard to build 11 pieces of wood
4 for the port **** looks pretty easy the hardest part would be the angle on the bottom to get it to slant i think

rpfuror, what program do you use for these designs???

To lay them out I use the formulas that are in the sticky for port length (actuall there are a couple that I use) and then crunch the number in an excel sheet I made.

To build them in 3d I use google sketchup.
