I don't, but I can design a box for you. See the link in my signature.

Well I guess I did not state this, but I don't have T/S parameters either. If I did, then there are many tools to help calculate this.

I will gladly accept T/S parameters for the LM-12 as well.
Any info is appreciated. BTW, I have searched on here as well as the greater web with no specs found. The Illusion Audio website seems to be long gone.

This is all the specs in the catalog I have:

Power Handling: 300W RMS
Sensitivity: 94 dB
Impedance: 4 Ohm
FS: 33 Hz
QTS: .4
Vas: 3.92 Ft3

Not much, but hopefully that helps.

The ND-12 needed about 1.5cf, sealed.

Found this list with a bit of google magic- no idea if it's accurate:
