need t/s psrameters for memphis mcp12s4

[srd150]

Memphis doesn't carry them in their site. Did some searching but only came up with the subs or some other t/s parameters . I doubt the place that sells them here will give them up cause they make boxes. They are kinda like that. They gave me recommended optimal. The port however doesn't make sense. I used Torres calc. To do their recommended port size. It's way too small IMO. 4ft^3 for two 12's with a port of 12x2.5x19long which tunes it to 28hz. I wanted to get what the actual T/S parameters are so I can get an accurate idea of how to build it.
