I think you messed up somewhere lol. Are you talking about port area? Because you should only need about 24" of port area. And the port length should be about 23" for a slot port, and 24" for an L port.

Umm...do you mean 024 instead of 420? Do you realize how much port area 420 square inches is.
Firtyfwe here ngz

2 wide
10.5 height
20 length
sound about right for 1.5 cubic feet?

Yes that is correct! When you do port area you do the Height X Width. Port length isnt calculated into this number.
Just an FYI: The port you said would be like 42" tall by 10" wide for example. Lol. Itd be a lil big for that 10 haha

Why the hell do you need an 8" aero for a 10" speaker?
CarAudio.com Veteran
Yea you would only need a 4" at most

wow. Yeah square as in square inches means multiplying two sides of something, not three- thats cubes. 2 by 10.5 would be 21 square inches and 420 cubic inches for a 20" long port. To use the 8" aero you would need two big tens, but this type of box makes them LOUD. One 6" works good for a big 10, usually sacrificing some SQ- big ports on small boxes usually dont sound the best.

I didn't know you could measure SQ by inches.

This box was built for two HDC3 10's getting 1500RMS each. 2.9 cubes. Its hard to get down in the 38hz range with a huge port and still fit two big subs in there. It helps large sub boxes get loud when they don't need 20" long ports for 38hz tuning, even given the same square inches of port per cube.
