I have a 4 cube box for a 15" oz audio ME. I have one small aeroport and was wondering if I add another one, would it get louder?

more port area generally means louder if thats what you are asking. but you will have to consider tuning if you add more port area.

you should probably have atleast 3 4" ports in that box. how long is the one you have in there now?

I'd say about 6"

you definately need more than that single port in 4 cubes

I had 2 4" in my 3.5cu box for my 15 Type R and it was ok...maybe 3 woulda been louder but never tried

Yes, you need more port area. One small aero for a 15 is too little.

a general rule is 15 square inches of port for each cubic ft. of air space.

so 4 cubes would need around 60 square inches of port aera

if you do the math 3 6" aero ports will be around 56-57 inches of port aera.

but you'll never need 3 6" aeros for a single 15.

Well actually it's not a 6. Just checked again for the exact size and it's a 4" aero port.

2 6" aeros would be 56"

+1. Thats what I came up with when I was doing my box.

So imma need 3 4" to get 56 inches of port area?
