I am getting around to the designing of the box. I was shooting for 1.5 sealed each sub, I will have 2 12" fi audio n2's. On the ported side it will be 6 cuft. After subs and bracing. I just don't know what to do with port.

I read you want half area of both subs together as well as 12-16 cubic iinches per cuft of box.

Help anybody gracias

So is this a blow through then? What kind of frequency response are you after? How much power are you going to be running?

Yes it's a blow through. Well I list in to mostly paisa rap Donna Summers stuff, so something around 30-60 would be cleeeaaan. I don't plan on blasting bass all day ima have a knob to turn it down and let the highs take over ?

Ima be running a soundstream xxx 6500 at 14v so like 4k watts? Hopefully haa

Ok, so the N2 really isn't going to work well in a 4th order bandpass. There is a reason its intended for ported use only. You are going to get a really peaky one note wonder.

If you are determined to put them in a 4th order bandpass anyway, I would use no less than 120 sq in of port area.

Purrfect sounds great.

Reason for a 4th is because if I knew how to do a 6th I'd be ALL over that bitch. If I could get somebody to help design it that would be great.

Lol, fair enough. I'd be happy to help ya with a 6th order design, but I don't feel like I have a good enough understanding of them to be comfortable giving designs to people. There are some other folks on here that do have good results designing them though and my be able to help you.

Thank you very much big dog for trying. I just don't wanna make it then hate it because I made it wrong. Measure twice cut once I think. Woods only 30$ a sheet. I think I'd be hood with 3 sheets.
