Aeroport curiosity

Yet another thread by me //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Anyways, would 2 6" aeros be fine for my IA DR 21"? 8.5 cubes

Technically it seems like it would be. I get 6.653 in^2/cube.

3 would be optimal in my opinion, But 2 will suffice ...

2 is enough. you will love the flow of 3 though

Your sentence has the flow too

The only thing is that 3 is an awkward number. It's hard to symmetrically place 3 aeros in my box.

make a triangle formation

Do 4 then. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

2 will help keep your sub from unloading as much below tuning as well...also easier to tune low(er) with just 2.

I was thinking about that as well. 2 aeros would be good for a lower playing in daily driving, without having to tune as low. And it saves box space.

3 aeros get my vote.As stated 2 will work but you WILL have better results with 3.Did testing on a 9 cube box with 2-3 aeros.tuning at 34hz

On a side note, the lowest you can tune with 3 stock full length(17") aeroports is 36hz. With a pair of aeros full length you can crush the lows with a tuning between 29-30hz.

Although the spec say 17in is max length, You can get 19 inches of legnth from precision ports and acheive lower tuning.

You don't put the pipe all the way into the rings?

An extra 2" is only a drop of 1.5hz anyways. I just prefer low tuned boxes myself. When you have capable midbass drivers being fed a lot of power and in deadened/sealed doors, you really don't need a sub to play over 50-60hz or so, so the typical lack of upper end response in a low(25-30hz) tuned box really isn't an issue most of the time.

I don't like crazy amount of midbass. IMO, a sub shouldn't play over 50-60 hz in the first place. That's why I was tuning DD's and AQ's to 30 hz.
