Getting the upgrade itch

Hello,

It's been awhile since I have posted on here but I have been reading a lot. I built awhile back 2 x 12 inch soundsplinter diy subs powered by a tapco j1400. I have a build thread on here somewhere.

I am thinking about doing a new build using the following drivers

RE Audio SEX15D4 15 inch subwoofers.

Fs = 31.53 Hz
Qms = 6.094
VAS = 2.527 cu.ft
Xmax = 21mm
Sd = 127 sq.in
Qes = 0.839
Le = 1.273 mH
Re = 1.384 ohms
Z = 1.66 ohms
Pe = 750 watts

I would like to build two sealed boxes. RE audio shows them to need 2.0 cu.ft for sealed.

Could someone model these in a sealed box. I would wire them both to 4 ohm load feeding them 1400 watts bridged.

Thank you
