2 15's or 2 18's in a 4.4ft^3 net box

Do you know what your port are per cubic foot is in this box you've got pictured?

port volume is .27ft^3

gross volime is 4.97

port area is 25.12in^2

So roughly a little less than 5 sq. inches of port per cube?

lol just about. you have to triple the port area to get within "general recommended" specs

adding more ports then...

I had 1 15" XFL in 4.7 cuft after displacement.

What you're asking for the amount of space you have isn't worth the time nor money.

I'm in the same stage as you.

I'm going to start learning all the shit I need to know on how to build a box, because I'm picky & I seem to believe a lot of others half-ass their box projects when it's something that should have time taken & invested into.

Just put a lot of effort into your box, don't rush it.

Make sure you 45 the corners.

wasnt it shown that 45's barely do shit?

[HunterJohnson]

45's decrease db's!!

I wanna make a box with computers that estimates frequency response and I wanna know how to optimize my cars.

I need to meet some scientists lol

[CleanSierra]

They don't have scientists for what you're looking for. They're called 3rd grade teachers.....

I kid

[HunterJohnson]

Lol hook me up with one!!

Didn't fecupe get a gain when he put 45's on the pressure points in that thread of his?
