im building a box for 2 15" obsidian v2s theyll be on 600 each daily. before woofer and port displacement im at 7 cbft. now ive researched quite a bit and the few different calculators ive used seem a little off. im aiming for 32hz and for a 4" dia. port there saying itll need to be around 1.79" in length??? that seems way off to me.
any aeroport experts wanna help me out?

What are the dimensions of the box?
What is the displacement of the subs?

Are you trying to use 1 4" port of that setup?

I thought you were using the comp 12's?

for 7 cubes net, you need more than 1 4" aero.

for 7 cubes, I'd use at least 3 4" aeros

sorry its been a bit. been busy at work. the box dimensions would be 20.5"DP x 40.5WD x 14.5HT inside dimensions. woofer displacement is .19"^3 each. and i just relized i put 4" i ment 6" aero port. and ya pro rabbit my deal with getting some feel through so on to different things

I would shoot for more port area with a box that big, you'll probably land around 6cubes after port and sub displacement depending on the size of the port you pick.

I had two sa 15's in 6 cubes after displacement and used a 9" aero 17" long. tuned me to 35ish

so maybe 2 6" aero ports 9" long?
