Well even though my subs are gone I figure it can't hurt to attempt to design a box regardless. So for a ported box to house two 10" subs that need 1.1 cubic feet of air per sub and sharing a single chamber with a single port that is 3" diameter and 8" length
Would these dimensions work??

External Measurements using .75" MDF

33.5" Wide
11.5" Deep
13.5" Tall

And having the one port on the front in between both subs

So do I somewhat have this design thing down or am I way off still? lol

 

depends... what was the displacement of the subs?

 

From what I measured they are (I think lol) .075 cubic feet of volume per sub.

 

the 3" port is too small, I would use a 4" port probobly...it would be better with a 6" but I know you are obviously short on depth so at least the 4" would help cut down on port noise a bit

 

Well they WERE two 10" Pioneer TS-W255C. They ended up going on me but like I said I figure I might as well make a theretical enclose on paper to learn how to design basic enclosure

OH and from what I found Pioneer said to use 3" diameter and 8" length on the port per sub sooo i dont know if that means thats still good for two or if i need to double the size.

 

so anyone know if that sub box/ a 6" wide, 8" long port would have worked well with those subs?

 

In that size of box, with that port, you'd have tuned the box to 66.72Hz. WAY too high for a daily setup, so it would not have worked out in your favour at all.

Why not port out the side? that way you could get some more length.
Or is your box going to be touching the sides of where you're mounting it?

 

Almost touching the sides. Why I said 6" is from shocking canadas suggestion. Like I said in my original post pioner sugests a 3" diameter and 8" long port. Though as I've said I'm not sure if thats ok for two subs in a common chamber.
But the box size is ok?
