The current version of the Minions is III. It uses a driver regularly stocked by PE. The driver for the Minions III is the Tang Band W3-1053SC 3" Full Range Driver. The driver runs full range, there is no crossover.

Unlike the original Minions and the Minions II, I chose a regularly stocked driver that is virtually identical to the Minions II driver except for the color of the cone.
The Minions II used this driver, which was a buyout driver and is no longer available.

The Minions III and The Minions II are identical except for the driver replacement.
I typically build them into a 4" internal dimension cube using 1/4" mdf, but have also made 4.25" internal dimension cubes and 4.5" internal dimension cubes. The larger cubes seem to give a minute amount of extended low end, but my goal was small and inexpensive so the majority of the cubes I have built were 4" internal dimensions.
Using 1/4" mdf these are panel dimensions for the 4" internal dimension enclosures
Back 4" x 4"
Sides 4" x 4.25"
Top/Bottom 4.25" x 4.5"
Baffle 4.5" x 4.5"
The round overs on all the edges are 3/8".
These pictures will give you an idea how much polyfil to use in each cube:


The only other picture I have of The Minions III it is a 4.25" internal dimension cube

Some pics of The Minions II
This hammered bronze speaker is the only one I made with 4.5" internal dimensions:


The remaining pics are 4" internal dimension cubes:



This picture shows an original Minion (the smallest cube) adjacent to my original 4" and 4.5" internal dimension cubes for the Minions II and III.

I'll leave it to you if you want to go for the smaller size of the 4" internal dimension cubes or if you want to try to squeeze out a few more low end Hz with the larger cubes.
I hope this helps those who have been struggling to find this information in the original Minions threads. I hope you like them.
