new box

[oldschool]

Ok so I am starting on my new box for 2 18s and need some help it will be around 8 cubic ft. After displacements and I need to know if 2 6in or 6 4in aeroports which would be better and how long would each port need to be to tune to 45 hertz.

how much power u tryin to push? cant fit 4 6in?

That's a little small for 2 18s. Is there any way you can get more volume? What car/subs/power?

[oldschool]

No I wish I could but this is going in the caddy and has to be subs and port forward so each corner will get 1 port and top and bottom between subs will get 1 port and I will be using 6000 for daily and 13000 for burps.

Agreed, I didn't know he was gonna be running that much power.

So which would be better the 2 6 inch or the 6 4inch aeroports and how long should which ever option be I am sorry about all the questions but in all the years I have been competing I have always used slotports and I have no idea about aeroports but I do not have room for a slot port and I thought I would try these worst comes to worst I can always put my old box back in if the aeroport thing does not work out also do any of you have experience going from slot to aeroports and if so did you see a gain thanks.

[Boon]

Can't you go back to slot port? That's really not enough port area... I used 2 6" aeros for a single 15 in a fart box.

I would say 6 6"s at a minimum if it's for burping. 4 for daily.

ok so everybody i talked 2 said do not use the aeroports in my situation so now i am going to try a 4th order bandpass because they said what i would gain in sub displacement i would loose in port area and cancellation because of phasing.
