Bass speaker cabinet design requires a certain range of knowledge to be learned way before selecting any particular driver.
It is best to leave speaker cabinet design to the professionals who have the training, experience and other resources required to design and build a bass guitar speaker system.
You will likely end up with something that does not perform as well as a commercially produced cabinet designed by a competent engineer that will have known performance specifications compared to if you begin the design process by having selected a driver without knowing what the entire process entails.
The 5-1/2 inch Dayton speaker is a subwoofer. It is probably not a good choice for a bass guitar cabinet. The 4 inch Eminence Alphas are also probably not a good choice for a bass guitar cabinet.
If you really want to build your own speaker cabinet, there are people who offer kits. Bill Fitzmaurice is one.

I have no experience with the Fitzmaurice kits, or speaker cabinet design in general.
If you want a micro stack that uses small diameter speakers, take a look at Phil Jones
