Front door speakers?

[Miyanc]

So lower on my list of issues is the front right speaker isnt working. I have a 2017 rex with the hk system. I have 2 options, first look up OEM and buy just 1 or look to replace the pair and maybe upgrade without going crazy.

I see mixed results and lots of upgrade options, but I am just trying to confirm what OEM would be and if it matters about hk for front door speaker replacement.
