The variables can't all be the same, each sub models differently due to the subs parameters and the application the sub is being used for. You're close on the TRIO12, and the Mack 5 should be 2.5 cu.ft tuned to 20 hz. It is also power hungry compared to the TRIO12.
Here's the modeling of the two. With 200 watts and the Mack 5 IXL-12 you can get away with one 4" port 31" long. The TRIO 12 needs a 6" diameter port 38" long.
Post the parameters for the TS-W301R, I can't find them. Thanks.
