a little under 2.5 cu ft per chamber, tuned to 30hz. 13.5 sq inches of port per cu ft.
I went with this design because I know that it works very well in ext cab trucks, thats why I am implementing it in the danger ranger. comments?

please tell me you know 13.5^2in is freaking tiny for a slot

please tell me you know 13.5^2in is freaking tiny for a slot 13.55 per cube, he wants loud to the ear but to also retain some good sound. not all of us are meter chasers tony... lol

Doesn't matter, the subs don't need much port area. Nick from obsidian has done testing on it as well as myself and they don't need much port.

I would have done a 6 or 8in round port with a v behind it.

How is the builder supposed to make that concave piece at the back of the port, why not just 45s?

sonotube and fiberglass. he said no aeros. so I did a slot. if he doesnt want to do the sonotube method I can swap it out for 45s with a few clicks...;)

Lot of times stuff like that is just for looks on the design, though I agree

I personally have avoided that type of design. Looking at the bottom pic, it looks like the dark brown thingy is creating a choke point right at the entrance to the combined section of the ports. If you were to use a piece of pvc piping there in the interior corners to identically replicate the radius on each side of the brown thingy, then it would look ok to me. Actually by glassing in a length of piping from the speaker side of the ports sounds like a very good idea with your design. Or, maybe using 2 pieces of wood and creating a triangle in place of the curved brown thingy and '45 ing the interior corners of the ports to perfectly match would work too.

My point is, at a glance, it looks like you are going to be tuning the ports pre maturely where they combine into one port section. I like my ports to be perfect dimensions throughout the entire length of the port without any restrictions that will alter the resonant frequency, this includes dowel pins as well. The atmospheric pressures in both chambers fluctuating in unison, combined with the atmospheric pressure inside the port, should be enough to counter act any suspected flex in the interior port walls.

Looks good though, Ranger man......just my .02... lol

In testing on my buddies f150, another buddies ranger, and an s10 as well as silverado subs up port side were loudest and very good sounding subs forward port up had a very flat response but got loud as well sub up port up was huge fail.

there are many more factors too it. I know people that do a 51 in a ranger with this design. it works very well in my experience.

Best of luck as soon as my buddies zv3-15 arrives for his ranger we will test it and post vids. And not really more to.it we build for daily meter is second on the list.

my buddy has 2 zv3 15s in the same style of design as this and he does a 148. on 3.5k, moves serious air, which is what fronty wanted. thanks for the input!

No worries dbeez, I'm with you on the design. All though for the vast majority of our builds we don't do port to the side for various reasons.

no offense was meant, I am just saying that I know that this design works, or at least what ive seen of it works... each situation is different.

It's an ext cab truck, loud is very very easy to do in my opinion. The harder thing is to make it work with in the guidelines of what the owner wants.

I'm sure it will work just fine, dbeez was just saying there are other ways and in some cases better ways then that to go. In the end as long as the client is happy...nothing else matters though.

he wanted it to be loud to the ear and get low... Im still very new at designing but I believe that it should perform very well.

where at?

I would add a horizontal dowel from the outside walls to the port walls then something running from the baffle to the back wall. I like to go overboard on bracing, but it gives you a really stout box. You can never have too much bracing imo
