RE calculator help

[Unfortunate 10+ year member]

edit: everyone here says use winisd but i can't figure that shit out.

Anyone want to help me out here?

bonesninja estimated .65 cubes displacement

that's for baffle/ 4" aero ports / subs

Going with whichever enclosure is smaller that will work

(ROUTE 1)

 

According to the psp calculator to fit (2) 4" ports i would need atleast 20in of length to the back wall for clearance which pushes me to 3.6 cubes and 3 cubes after displacement.

(ROUTE 2) 3 cubes slot port box with about 2.5 cubes after displacement. ((40^in of port))

Any good box designers you'd suggest to figure this out because i do need a design and cutsheet today

what do i enter for square port width / length
trying to build a box that's 3 cubes gross so about 2.5 net after sub/port displacement.

How do i go about doing so? anyone want to help with dimensions along the times of

30 width

13 height

?? depth

40 sq in of port tuned to 38 hz *

The re caculator isnt very accurate, I'd use winISD if I were you!

Integral of xsin(2x) is -(X/2)cos2x + (1/4)sin2x + c

I think......my brain hurts now....

Yea, I tried to use winisd when I built my box, didnt like it, I think its very poorly/confusing designed software and the re calculator is much easier to use.

As far as it being inaccurate, Im not sure how punching in 2+2 on one calculator is any different than putting it in on another one.

Anyways back to your box, what is your total sub(s) displacement?

Sounds like you got the right idea w/ slot ported, what are you lookin for as far as tuning? Again what is your subs(just subs) total displacement, you dont need to know the baffle/port size that will vary depending on how big the box is. Im working right now but ill try to help as much as i can.

Thanks appreciate it.

(2) dd 1510's (displacements = .216 cubic ft total)

baffle = 11.5 x 28.5 inches (3/4" mdf)

Tuned to 38hz

Ok got your box, type this in the re calculator. W=30 H=13 D=17.5(top and bottom depth) Port Width=3.5 Port Length 2=6.25......you get 38.076hz....this help?
