port length and diameter is based on??

what are the measurements you have to work with?

Its a false floor so I don't know the exact specs. There is no chambers at the moment just external "shell" if you want to say. I'm at over 2^3 at the moment so the builder is trying to get the right port size down. Here is what the build is kind of right now.

The top view and the side view. I am either looking at making both like the right side of the lower drawing or both like the left side. Just need to see if there is an issue making the port like either. The guy building it is just wanting to know what the port length and diameter should be. The black space on the left would be empty space if the left port length would work. It would be on both sides.

Wow. You're going to hate that thing... no offense. different port lengths. It's a really bad design. Might look nice but won't perform worth a ****.

Come on Crack gotta read. Im either having the right side done or the left. Inside hasn't been done. They WILL NOT be different ports

I'd try running the port under the amp. coming out next to the other sub. One would be in front of the other. If you can get some measurements with the drawings I will see how big the ports can be.

I read it. It didn't make sense to me so I commented. You are killing me though. You asked for help, and when people give it to you, you argue. It looks like you wanted a circle jerk of people telling you how awesome your idea was. Instead of doing that and setting you up for disappointment, we are trying to prevent you from making a mistake and wasting money. You should listen to us. We are on your side even though it might not sound that way to you right now.

Not arguing at all, kinda hard to do expression. guess i should have said lol. I don't understand why it will sound bad if i run the port under the amp thou.

I think it will be fine. You are using external ports; I don't think that was clear at the beginning. How much space do you have to work with under the amp?

Guess i don't understand external ports then. Thought that having the port under the amp was still an internal port and external port would be outside the box. say an aero port that is outside the enclosure. i didn't know you could do an external slot port.

There is near a cube under the amp.

You will gain more space when going with one port instead of 2, and obviously this is a concern of yours. Also with this, port area can be bigger and more effective. Group the subs together in a common chamber on one side, port on the other side.

This would be what I think as well. Hard to say how it will perform as you don't even know the dims of the enclosure. With out knowing that I'm not sure how you can create a port with the correct port area and length for tuning.

You can take a guess I supposed, but then your stuck if you don't like it. Are you using an enclosure builder or just a good carpenter? Any decent enclosure builder should be able to figure out the specs on the space you have to work with and figure out a decent option for the application.

Yeah im using Audio 2000 here in Tucson. He knows the specs/dimensions of it. I just don't and he was asking if i knew a way besides email to reach Jacob for port length and diameter. I only knew what he told me about .6 @35 htz. Ill go with both subs on one side and port on opposite if i have too. again its not cut for the subs yet
