Default round port converted to square port

i have no idea how to figure this out, i just want someone to tell me what to build [email protected]ty simple, i want to build a box for a 15" t-600 but when i asked what kind if enclosure it would do good in, I got this...

Sealed enclosure 1.65 cubes.
Ported 2.5 cubes 4" dia.port 8" Long.

I dont want to deal with buying a port, so i want it converted to a square port... so i asked him how to convert that to a square port, and he said this...

A 4" Round port would be 2 x 2 x 3.14= 12.56in2 o convert that to a square or slot. (1 x 12 etc)

Theile Smalls below....

Re = 2*4 ohm

Fs = 32.7575 Hz

Zmax = 25.4739 ohms
Qes = 0.8340
Qms = 8.6749
Qts - 0.7~09
Le = 1.3937 mH (at 1 kHz)
Diam = 323.8500 mm (12.7500 in )
ConeArea =82371.6372 mmA2(127.6763 inA2)
Vas = 67.8294 L (2.3954 ftA3)
BL = 24.9431 N/A
Mms = 278.3329 g
ems = 71.1775 uM/N
Kms =14049.3877 N/H
Rms = 7.2085 R mechanical
Efficiency = 0.3584 %
Sensitivity- 89.5441 dB @1W/1m

This is like reading spanish...i have no idea what that means, i was never good at math, just need someone to simply tell me how ever many cu ft tuned to whatever and i will figure it out from there
