port area vs. volume - a sacrifice must be made!

[n8ball2013]

Exactly I run mine jn 4.25 per with 17 sq in per with about 3k on each. I like to think its working well

I may just have to try my hand at a custom port. I have enough volume for 10 cubes net, just no space for the hole. I have 8 inches between the woofers. I may be able to make the port like the Hurley symbol to get that extra few square inches. I'm so close to perfect for what these woofers want and I know they will pound the shit out of my car. Ugh.

The other cure for this is smaller subs. If you dont have room to give 15s the proper airspace and port that they need, you will be better off with 12s and give them what they want instead of choking off the 15s in some way or another.

What are ya building the box for? Max spl or musical? What are ya gonna tune it to? You gonna do comps with it?

[JamieHoward]

Just want a loud daily. I will not be competing. I really don't think I will be choking them. I am very close to DD specs, just not QUITE.

[JamieHoward]

GOT IT!! I had to flare the top and bottom out to get enough area, but now I have enough volume AND port area. This thing is gonna slam!! Gonna suck to build tho....

[Bump4life]

when dealing with things this close triple and quadruple check measurements. dont want to be off even by a quarter inch!!

hope it all works out!! is that design 3 net per or how big?

[JamieHoward]

Net volume yet to be determined, but greater than 4 cubes per. Like I said, I have plenty of room. Net volume will be determined by what I am limited to in port area.

I know this might seem crazy but I'm running this by you to keep you thinking:

What about an Octagonal port?

You may be able to keep port tuning and area at the same time, while maintaining less area on the baffle?

Just wrapped up the design a little while ago:
