Refurbishing black ash speaker cabinets

Hi all,

I just bought a pair of Epos ES14s in black ash finish. They were a good deal but they are a little rough cosmetically.

I would like to clean them up and refurbish the cabinets. They need to be lightly sanded and repainted and they have a couple of dented corners. Can anyone recommend a paint to recreate the original finish? And does anyone have any tips on fixing flattened corners?

Thanks in advance.
