Alex K Posted January 2, 2011 Report Share Posted January 2, 2011 I could have went with like 6 10's in my trunk, and done a slot port, but ive heard about gaining about 3db with aero ports (precision ports) so i made it possible to use one. I'm using 1 8" on 4 10s. It just seems more logical to me, since most instruments like trumpers, tuba, etc all use the same concept of a flared cylinder, why use a square? :? lol. But thats just me.

Skrilla Posted January 2, 2011 Report Share Posted January 2, 2011 Well, Steve's old setup had 4 18's using only 6 4" aero ports. That's only 75in of port area. He said he really didn't have any port noise. With that being said, I would think you can use 1 8" aero port (50in of port area) for 1 18" sub and get away with it, especially if you only have a 6-7cuft box...?

Skrilla Posted January 2, 2011 Report Share Posted January 2, 2011 ^That's about 12.4 in of port area per sqft, which is within the 12-16in of port area per sqft rule... Sounds like enough to me Quote 2 HDC3 18's AQ2200D Link to comment Share on other sites More sharing options...

Use the search bar. If you have a question, you can usually always find an answer on here. If that fails, there's always Google, lol. Here's what I found with a quick search. http://forum.realmofexcursion.com/enclosures/22705-pencil-paper-101-a.html <Good basic info here...
