Adire has several "white papers" with reference designs for their subwoofer drivers.
Unless you want to use the LSPcad program available on their web-site to design your own enclosure, I would strongly suggest you build one of their proven reference designs if you decide to use one of the Adire drivers.
The bass response of a subwoofer is VERY LARGELY affected by the size of the enclosure and how (or if) it is ported / tuned.
To throw a great driver in a haphazardly sized box will likely produce bass, but be anything but flat in its response. In a word, it won't sound very good and your efforts will be a waste of your time.
It has been said many times that most "car" subwoofers will do very poorly in a home theater when they cannot take advantage of the "cabin gain" that occurs in a car. Stay away from them unless you know what you are doing.
One more thing... the subwoofer enclosure construction is very likely to take you the next two days even if you have all the materials handy. You need to start making sawdust now if you want to get things done by the 2nd.
So... 1. choose a driver
..... 1a. order driver
..... 1b. order sub-amplifier
..... 2. design a enclosure (or use a reference design)
..... 2a. purchase materials for enclosure
..... 3. make sawdust
..... 3a. assemble enclosure
..... 3b. finish enclosure
..... 3c. wait for UPS truck
..... 4. mount driver and amplifier
..... 5. wrap with red ribbon and present as gift
Yup... at least two days effort...
