Design Porting For Me Please!

[JeffyZ33 10+ year member]

Ok the plan is i'm going to toss 4 10'' subs in my S10. I plan on doing 4 RE RE. I really don't understand a whole lot about the whole porting idea or how to make it. I'd really appreciate it if somebody could design me an inside port for it. I really dont care where it comes out, top would probably be best.

Here's a pic of the box I'm going to be building. If somebody could design me a port for it it would be awesome. It will be made out of 3/4 MDF. I want it tuned to about 30hz. Thanks.

well if that pic is the wrong one, then we have no measurements to base the port size on.

Sorry just realised i couldn't fit 1 15'' so i'm going with 4 10''s. The D1, D2, W, and L are all the same though. I'm sorry if anybody started.

ok ready...total volume after displacements will be around 5ft^3. i would go 3-3"ports on top. here i'll just draw a pic....

What will that tune it to? Thanks //content.invisioncic.com/y282845/emoticons/clap.gif.178cba2c538c68e720c727fcb024b19c.gif

I thought there was a lot more to ported boxes? What lengths would I need to cut those to?

That would make the box tuned to around 47hz, but when your runnin 4 subs you need to figure out the displacment of the subs and how much room they take up because once you put in all of those subs the box will only have like 4 cubes... plz correct me if im wrong!!

i put it in BBP6. you cut them to 10". i figured .15ft^3 per sub. and its tuned to 30Hz

I think .15 is a bit too much for the tiny RE RE's isn't it? How much of a difference would it be if I put in 12''s instead of 10''s?

Is that program free? If so can you tell me the name of it so I can DL it. Thanks.
