Speaker advice for cabinet project

I have an old Eden cx112 cabinet at my shop that I got in a trade basically for free. Catch is it has no speaker and the original crossover is gone.

Cab looks like this and is 15.25w x 25.5h x 14.5d

I'm looking for an appropriate speaker. I would kind of like to give coax a try but could be swayed in any direction. I don't really need this project but the size and shape of the cab seems very appealing to me so I'll do it if it can turn out cool. any advice would be appreciated.
