Good quality comms speaker?

[SpaceForceCmdr]

I have an FTDX10, and besides the Yaesu external speaker, what would be a better option for maximum intelligibility? I actually have a Polk center speaker lying around, but it's pretty dang big. What about a small, bookshelf speaker? Also, I see the SP-30 is 4 ohms. Would it be a problem to run an 8 ohm speaker with the FTDX?
