I **** at sketch but hopefully you can understand it. Those are external dimensions. 3/4" mdf board.



18" Tall X 28" Deep X 33" Wide

Port width is 3"

The board on the inside of the box for the port is 23.5"

This is for two 15" Kicker CVRs

having a hard time understanding what you are saying.

But the port is not L shaped. its a straight back port.

Pretty sure it's 6.34cu ft after port, tuned to 32.7hz. That's if the port extends to 3" from the back wall, which it looks like it does

Oh, actually I see so it's 5" away from the back wall, should be tuned at about 34hz then

About 6.2 cubes @ 29.5Hz

34Hz would only be 11.xx" port length.

here is a different angle



Ignore the dimensions at the top right. They will probably confuse you.

 

[dB-SPL 10+ year member]

Yeah.. It's 6.2 @ 29.4 - 29.5Hz. I'm pretty sure.

You sir are correct !!!

how are you figuring this up?

I used the RE calculator



You will notice that according to that picture the width is 18 and height is 33. Thats because I am going to be rotating the box in the vehicle where the subs are on top and port is facing the back towards the bottom. So they width is actually the height and the height is actually the width.

But according to it its tuned to 32 hz.

I don't use most of the online calculators so I'm not that familiar with them, but I see that you have port length 1 as 24.25" and total port length is 29.5" which is where you went wrong. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

where are you seeing this?

what program are you using? or are you doing it mathmetically?

If you want a 23.5" port then why are the arrows pointing to those numbers. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif I use LEAP, WinISD and pencil & paper.

you cant change those two numbers.

 

[dB-SPL 10+ year member]

you cant change those two numbers.

With that calculator, you have to use different box dimensions to change those numbers. Are you getting why I don't like using most of them, now? //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
