DC Lvl 3 15 Port Area

[matt_martin87 10+ year member]

I plan on building a ported box for my soon-to-come DC Lvl 3 15. Box will be 3 cubes at 30hz or 28hz. I'm feeding it 500rms. Could I get away with using (1) 6" PVC Port? This figures out to be 9.x sq in. of port area/cuft. With L-Ports it's suggested that you use 14-16 sq in/cuft. With aeros it's supposed to be less, around 6-9 sq in from one article I read. This seemed a little low to me for the Level 3 15. Thoughts?

A single 6" aeroport is adequate for most 15" subs. I doubt you'll have any issues with port noise since those flares really help cut down on turbulence.

You could do three 4" aeros to give you a little more output, but I don't think it'll be needed.
