I Need an Enclosure Genius

[MikeMartel 64]

Last time i made calculations I didnt account for a few things including the end correction of my slot port. I hope somebody with a lot of enclosure knowledge can help me out with this.

Port Area

126 inches2

Port Tuning

32hz

Port Internal Dimensions

9” x 14” x 39.85”

Port Displacement (8.25” of the port will be external)(31.6” Internal Port)

9.75” x 15.5” x 14.25”

=1.24625651 cubic feet

9.75” x 15.5” x 12.1”

=1.058 cubic feet

1.24625651 + 1.058

= 2.30 cubic feet + 0.18 cubic feet (Subwoofer Displacement)

= 2.48 cubic feet (Total Displacement)

Subwoofer Dimensions Needed (9.23 cubic feet)

36 x 15 x 35.75 = 9.231 cubic feet before displacement

9.231 – 2.48

= 6.751 cubic feet net

I'm at 32.92 Hz with that calc (in bassbox pro6) , so port needs to be a tad longer , with the same internal volume you need a 42,77 inch long port including flares

could help a bit more but need thickness of walls

Im not using aero ports first of all.. And have you made sure to adjust for end correction too? Walls are 0.75" thick.

you should really considder seriously rounding of those ends . I was wondering if this is going to be a box for comps because port is rather large , take airspeed up to 24m/s in port so the port can be a lot smaller and thus shorter , safe/efficiciennt enough for daily

that box is only 0,75 thick all round ? I'd up it to at least 1inch and brace it well with rods

end correction was used . I'm off very seldom , and when it happens usually the builder did something wrong , I'm no genius though .

Alright, according to the calculator im using i need 39.85" long of port, I guess thats why im off a bit according to your calculator.
